Raspberry Pi Connect

Introduction

An image showing three different Raspberry Pi Connect screens: the user interface, the operating system graphical user interface, and the Terminal view.

Raspberry Pi Connect provides secure access to your Raspberry Pi from anywhere in the world. It works by linking your device to your Connect account.

Connect is installed by default in Raspberry Pi OS Desktop and Raspberry Pi OS Full (desktop with recommended software).

An alternate Lite variant of Connect, which supports only remote shell access with no ability to screen share, is installed by default in Raspberry Pi OS Lite.

Note
To use Connect, your Raspberry Pi must run Raspberry Pi OS Bookworm or later.

Connect service features

After you have linked your Raspberry Pi devices to your Connect account, you can interact with them in the following ways:

Connect menu

The Connect menu allows you to turn Connect on and off, sign in and out, and enable or disable the two remote access methods (shell and screen sharing).

The Connect menu allows you to turn on, manage, and turn off the service.

Security and data storage

Connect uses a secure, encrypted connection.

By default, Connect communicates directly between your Raspberry Pi and your browser. However, when Connect can’t establish a direct connection between your Raspberry Pi and your browser, we use a relay server. In such cases, Raspberry Pi only retains the metadata required to operate Connect.

Connect account types

There are two types of Connect account: personal and organisation.

The personal account provides a single user with a view of all the devices linked to their Connect account. This account type is free.

The organisation account allows multiple users to view devices linked to a shared Connect account. This account type is billed monthly. For more information, see Connect for Organisations.

Get started

There are three steps to get started with Connect:

  1. Sign in to connect.raspberrypi.com with your Raspberry Pi ID. For more information, see Create a Raspberry Pi ID.

  2. Turn on the Connect service on your Raspberry Pi device, then link it to your Connect account.

  3. From your PC, Mac, or other device, visit connect.raspberrypi.com to remotely access your linked devices in a web browser.

The full versions of Raspberry Pi OS include Connect, but the service is disabled by default. You must therefore turn it on before first use.

Turn Connect on and link it to your Raspberry Pi device using the desktop, the command line, or an auth key.

Note
Connect signs communication with your device’s serial number. Moving your SD card between devices signs you out of Connect.
  • Desktop

  • CLI

  • Auth key

To enable Connect and link your device:

  1. Power on your Raspberry Pi device.

  2. From the Connect icon in the system tray, select Turn On Raspberry Pi Connect.

    The Connect interface, showing the Turn On Raspberry Pi Connect dropdown menu option.

    If this is the first time you have turned on the Connect service, or if you aren’t signed in with your Raspberry Pi ID, a browser opens.

    The Connect page with a prompt to sign in to Connect with your Raspberry Pi ID.
  3. Enter your Raspberry Pi ID email and password, then select Sign In.

  4. Follow the on-screen prompts to give your Raspberry Pi device a name and choose which Connect account to link it to.

    The Connect page inviting you to create a new device and sign in.

    If you’re an administrator of an organisation, select whether to add this device to your personal account or to a specific organisation.

    The Connect page, showing the new device account selection screen.
  5. Select Create device and sign in.

    When you’ve completed these steps, the Connect icon in the system tray of your Raspberry Pi device turns blue to indicate that it’s signed in to the Connect service.

    A notification is also sent to your registered email address to inform you that a new device is linked to your Connect account.

    The Connect page, showing the account sign in notification screen.
  1. Turn Connect on by running the following command:

    $ rpi-connect on

    This turns the Connect service on, but doesn’t sign you in.

  2. Sign in by running the following command:

    $ rpi-connect signin

    This command outputs something like the following:

    Complete sign in by visiting https://connect.raspberrypi.com/verify/XXXX-XXXX
  3. Visit the verification URL on any device and sign in with your Raspberry Pi ID to complete the linking process.

    When you’ve completed these steps, the Connect icon in the system tray of your Raspberry Pi device turns blue to indicate that it’s signed in to the Connect service. A notification is also sent to your registered email address to inform you that a new device is linked to your Connect account.

    You can also type rpi-connect status into the command line to check the status of the connection.

    The Connect page, showing the account sign in notification screen.

An auth key is a single-use, temporary token that lets you link a device to a Connect account automatically (without using the web interface). Personal auth keys expire six hours after creation; organisation auth keys expire between 1 and 90 days after creation (1 day by default).

The easiest way of creating and using an auth key is by using the customisation options in Imager. You can also manually create an auth key from the Settings page of a personal or organisation’s Connect account, and organisation administrators can create auth keys using the management API.

Note
Personal accounts can only have one auth key active at a time; organisations can have multiple auth keys active at once. You need a unique auth key for each device.
Tip
To use an auth key, ensure that you boot your Raspberry Pi and connect it to the internet before the expiry time shown on the Raspberry Pi Connect website.

After creating an auth key, provide this to your device using the rpi-connect signin command, or by writing the auth key to a file in your home directory.

Alternatively, save it to .config/com.raspberrypi.connect/auth.key in your home directory so that Connect detects it automatically.

To provide your auth key as a string, run the following command:

$ rpi-connect signin --auth-key=rpuak_123456

If you’ve saved your auth key to a file, you can pass its full path to the command by prefixing it with @:

$ rpi-connect signin --auth-key=@/home/alice/auth.key

When you’ve completed these steps, the Connect icon in the system tray of your Raspberry Pi device turns blue to indicate that it’s signed in to the Connect service.

A notification is also sent to your registered email address to inform you that a new device is linked to your Connect account.

The Connect page, showing the account sign in notification screen.

Security best practices

If you receive a notification email for a device that you don’t recognise:

  1. Change your Raspberry Pi ID password immediately.

  2. Follow the instructions in Remove the device from Connect to permanently disassociate it from your account.

  3. Consider enabling two-factor authentication to keep your account secure.

View linked devices

Connect lists all your linked devices on the Devices tab.

To view your devices:

  1. On any device, sign in to connect.raspberrypi.com.

  2. Select the Devices tab. Connect displays a list of linked devices.

    The Connect page, showing the linked devices screen.

If you’ve an organisation account, you can search and filter this list, and add tags to devices.

Access your device in Connect

After you’ve linked your Raspberry Pi device to your Connect account, you can access it from anywhere using only a web browser.

You can do this using either of the following methods:

  • Screen sharing

  • Remote shell

Screen sharing requires the Wayland window server. Raspberry Pi OS Bookworm and later use Wayland by default. Screen sharing isn’t compatible with Raspberry Pi OS Lite or systems that use the X window server.

Screen-sharing interface

Connect’s screen-sharing interface is designed for both desktop and mobile devices.

The Raspberry Pi Connect screen-sharing interface, which includes common keyboard function toggles and keys at the bottom left of the interface.

You can simulate common keyboard functions using the buttons at the bottom left of the interface:

  • Keyboard. Toggles the on-screen keyboard. Displayed only on mobile devices.

  • Ctrl. Simulates holding down this key on a physical keyboard.

  • Super key. Simulates holding down this key on a physical keyboard.

  • Alt. Simulates holding down this key on a physical keyboard.

  • Esc. Simulates a single press—pressing and then releasing—of this key.

  • Tab. Simulates a single press—pressing and then releasing—of this key.

You can also use the buttons at the top of the browser window to complete other useful tasks:

  • Copy from remote. Transfer text from the device’s remote clipboard to your local clipboard.

  • Paste to remote. Transfer text from your local clipboard to the device’s remote clipboard.

  • Enter full screen. Expand the browser window to full size.

  • Disconnect. Terminate the sharing session.

Remotely update your devices

Connect includes the ability to update your Raspberry Pi devices by remotely pushing them updates.

Remote updates are useful for updating devices behind a firewall, and devices that are physically remote or hard to reach.

Connect supports two types of update artefact:

  • Script artefacts, created with otamaker, run a shell script as root on the device. They work on a standard installation of Raspberry Pi OS and suit maintenance tasks such as upgrading packages.

  • A/B boot updates, created with rpi-image-gen, replace the entire operating system and automatically revert to the previous version if the update fails. They require imaging the device with an A/B boot layout first.

Whichever type of artefact you build, you deploy it from the Raspberry Pi Connect website, as described in Deploy the update artefact. You upload the artefact as part of the deployment, and Connect passes it to the recipient device.

If your devices belong to a Connect for Organisations account, deployment works differently: instead of uploading the artefact, you host it yourself and give Connect its location. An organisation’s devices also don’t have to be online when you deploy; they’re updated the next time they sign in to Raspberry Pi Connect. For more information, see Deploy remote updates in an organisation.

Deploy the update artefact

After you’ve built an artefact with otamaker or rpi-image-gen, use the Raspberry Pi Connect website to deploy it to a device.

Note
If the recipient device belongs to an organisation, deploy it as described in Deploy remote updates in an organisation instead.

Deployments always start from the device you want to update, so make sure that the recipient device is registered to your personal account, and that it’s online, before you proceed:

  1. Log in to Raspberry Pi Connect.

  2. Select the Personal account using the account switcher at the top right.

  3. Go to the Devices tab, then select Deploy next to the recipient device. Deploy appears only for devices that have remote update enabled and are currently online.

This opens the New deployment form, which creates a new artefact for the deployment in two steps.

In Step 1: Create an artefact, upload the artefact you built:

  1. Enter a Name for the artefact. Names don’t have to be unique, so use something that helps you recognise the deployment later, such as a version number.

  2. Drag the artefact onto the File area, or select browse to choose it. The file must be a Zstandard-compressed tar archive (a .tar.zst file) of 2 GB or less.

  3. Wait for both Checksum and Upload to show Complete.

    To choose a different file, select Remove. To abandon a file that is still uploading, select Cancel.

  4. Select Next.

    Step 1 of the New deployment screen in Raspberry Pi Connect, showing the Name field filled in and an uploaded artefact file with its checksum and upload both complete
    Step 1 of the New deployment form, showing the Name field and the uploaded artefact.

In Step 2: Deploy to device, check the name, file, and SHA-256 checksum, then select Deploy. If you spot a mistake, select Back to correct it.

Step 2 of the New deployment screen in Raspberry Pi Connect, showing the name, file, and checksum of the artefact to be deployed, with a Deploy button
Step 2 of the New deployment form, showing the artefact’s details for confirmation.

Connect keeps the artefact you uploaded for two hours, then deletes it. A deployment that hasn’t started by the time its artefact is deleted is marked Invalidated. To deploy that artefact again, upload it again.

Monitor the deployment

From the Devices tab in Raspberry Pi Connect interface, you can select a device and then view a list of the most recent deployments uploaded to it.

Deployment states are:

  • Pending: waiting for the recipient device to pick up the update.

  • In Progress: the update is being applied to the device.

  • Succeeded: the update has been applied successfully.

  • Failed: the update failed. For more information, see Troubleshooting.

  • Cancelled: the update was cancelled before it could be applied. Pending deployments are automatically cancelled when another deployment is queued for the same device.

  • Invalidated: an update that can no longer be applied.

When a deployment is Pending or In Progress, the Devices page automatically updates with the current state. It stops updating once the deployment has entered Succeeded, Failed, Cancelled, or Invalidated.

To check a deployment’s details:

  1. Log in to Raspberry Pi Connect.

  2. Select the Personal account using the account switcher at the top right.

  3. Go to the Devices tab, then select the device you deployed to. The Deployments section lists the most recent deployments for that device.

  4. Select a deployment from the list to read more about its state, or to read any error messages for a failed deployment.

To cancel a deployment:

Note
You can only cancel a deployment that is Pending.
  1. Log in to Raspberry Pi Connect.

  2. Select the Personal account using the account switcher at the top right.

  3. Go to the Devices tab, then select the device you deployed to. The Deployments section lists the most recent deployments for that device.

  4. From the deployment list, select the deployment you want to cancel, then select Cancel.

Verify the deployment

To verify a deployment, see Script artefacts for a script artefact, or A/B Boot Update for an A/B boot update.

Script artefacts

A script artefact packages a shell script that Raspberry Pi Connect runs as root on the recipient device. Use script artefacts for maintenance tasks such as upgrading packages, changing configuration, or installing software.

Unlike an A/B boot update, a script artefact doesn’t require a special partition layout, so you can deploy one to any device running a standard installation of Raspberry Pi OS. However, there is no automatic recovery if a script fails, so test your scripts carefully before deploying them to remote devices.

Use otamaker to create script artefacts.

Prerequisites

The following are required to create and deploy a script artefact:

For the recipient device receiving the update artefact:

A Raspberry Pi device that is:

  • Connected to the internet.

  • Registered with, and signed in to, your Raspberry Pi Connect account.

  • Running the latest version of Raspberry Pi Connect or Connect Lite with the rpi-connect-ota package installed:

    $ sudo apt update
    $ sudo apt install rpi-connect rpi-connect-ota

    If you use Connect Lite, install rpi-connect-lite instead of rpi-connect.

  • Opted in to remote updates, which rpi-connect manages using its ota (over-the-air) subcommand:

    $ rpi-connect ota on
For creation of the update artefact using otamaker:
  • The otamaker utility, which is included in the rpi-connect-ota package.

    Tip
    To build artefacts on a computer other than a Raspberry Pi, download otamaker from the utils repository on GitHub.

Step 1: Create the script

Write the shell script you want to run on the recipient device. The script runs as root, so it has full access to the device’s filesystem.

Use the script’s exit code to report the outcome of the update to Raspberry Pi Connect:

  • 0: the update succeeded.

  • 1: the update failed.

  • 2: the update succeeded, and the device must reboot to finish applying it.

For example, the following script, saved as aptupgradescript, upgrades all of the packages installed on the recipient device, and reboots it if any of the upgraded packages require a reboot:

#!/bin/sh
export DEBIAN_FRONTEND=noninteractive
if ! apt update; then
    echo Package index update failed
    exit 1 # EXIT_FAILURE
fi
if apt -y -o DPKG::Options::="--force-confnew" upgrade > output.txt 2>&1; then
    if [ -r /var/run/reboot-required ]; then
        echo Rebooting to finish the upgrade
        exit 2 # EXIT_REBOOT
    fi
else
    echo Upgrade failed:
    echo
    cat output.txt
    exit 1 # EXIT_FAILURE
fi
echo Upgrade complete
exit 0 # EXIT_SUCCESS

Anything the script prints to standard output or standard error is recorded in the recipient device’s systemd journal, which you can view after deployment to verify the update or diagnose a failure. The example script captures the output of apt to a file and prints it only when the upgrade fails, so a successful run records just Upgrade complete.

Step 2: Create the manifest

Next, create a YAML manifest that describes the artefact and the payloads it contains.

The following manifest, saved as aptupgrade.yaml, packages the script from Step 1:

# Run apt upgrade on a remote device
artefact:
  name: aptupgrade
  version: 1.0
  device_type: rpi

payloads:
- name: aptupgradescript
  type: script

The artefact section names and versions the artefact. The payloads section lists the files to package: each payload’s name is the name of a file in the directory where you run otamaker, and a type of script tells the recipient device to execute it. To package a file from another directory, add its path as a comment after the payload’s name, for example - name: aptupgradescript # scripts/aptupgradescript.

Step 3: Build the artefact

Build the artefact by passing the manifest to otamaker:

$ otamaker aptupgrade.yaml

This creates a Zstandard-compressed update artefact (.tar.zst file) containing the manifest and the script, and outputs the artefact’s SHA-256 checksum.

Step 4: Deploy the artefact

Deploy a script artefact in the same way as any other update artefact: select the recipient device and upload the .tar.zst file to it, as described in Deploy the update artefact.

If the recipient device belongs to an organisation, host the artefact first, then deploy it using its URI and checksum, as described in Deploy remote updates in an organisation. You can skip the step that calculates the checksum; otamaker already output it when it built the artefact.

Step 5: Verify the update

When the deployment shows as Succeeded, connect to the recipient device using Raspberry Pi Connect and view the script’s output in the systemd journal:

$ journalctl -t rpi-ota-connector

A/B Boot Update

The A/B boot update prevents a failed or faulty update from causing your device to stop working.

The configuration has two independent slots, each made up of a boot and a system partition. Slot A is used for the existing operating system (OS) and slot B is used for the update. The device boots from slot B, but reverts to booting from the known working partition, slot A, if that fails. This process repeats with each successive update.

Configuring for A/B boot requires being able to physically access the device. This is because you must image the device with the appropriate A/B boot layout. However, once configured, you can then deliver remote updates using Raspberry Pi Connect.

Raspberry Pi 5 and later devices that use EEPROM boot can also be configured to use A/B boot update. See A/B bootloader updates.

Use rpi-image-gen to create both the A/B boot configuration (.img file) and the update artefacts (update.tar.zst files). Use Raspberry Pi Imager to configure the .img file and write it to the storage device for transfer to the recipient Raspberry Pi.

Prerequisites

The following are required to use remote update and the A/B boot configuration:

For creation of the A/B boot configuration and creation of the update artefact using rpi-image-gen:

A Raspberry Pi device on which is installed:

  • The latest 32-bit or 64-bit version of Raspberry Pi OS (Trixie).

  • rpi-image-gen.

  • The latest version of Raspberry Pi Connect or Connect Lite.

  • The latest version of Raspberry Pi Imager.

To configure the recipient device for A/B boot:
  • A storage device (typically, microSD) to save the A/B boot layout to and a way to connect the storage device to the Raspberry Pi.

    You must have at least 16 GB of space, but you must decide exactly how much disk space you need based on your expected future requirements for the boot partition (firmware, kernel, device tree files, and possibly initramfs) and the system partition (kernel modules and system-level software such as the standard Linux command-line utilities).

For the recipient device receiving the update artefact:
  • Raspberry Pi 4 or later that is:

    • Connected to the internet.

    • Opted in to remote updates.

    • Registered with, and signed in to, your Raspberry Pi Connect account.

Implement A/B boot and remotely update the first image

Follow the three stages below to implement the A/B configuration and send updates using Raspberry Pi Connect:

  1. Stage 1: Prepare the recipient Raspberry Pi 4 and later device for remote updates by creating an A/B boot file, then deploy it to the device.

  2. Stage 2: Create an update artefact file for deployment to the recipient device.

  3. Stage 3: Use Raspberry Pi Connect’s remote update feature to deploy the update artefact to the recipient device, then verify the update.

Stage 1: Create A/B boot configuration

Standard Raspberry Pi OS installations don’t feature an A/B boot configuration. This stage shows you how to create one using rpi-image-gen and Raspberry Pi Imager.

rpi-image-gen outputs an .img file containing the A/B boot image.

Raspberry Pi Imager then uses the .img file to write the operating system configuration to the storage device. This includes opting the device in to remote updates so that Raspberry Pi Connect can update it.

You must have physical access to the recipient device to update it for the first time, but once you’ve configured it, you can send updates remotely thereafter.

In Step 3, you generate an auth key to allow the recipient device to link to the Raspberry Pi Connect website. This auth key is tied to a single recipient device, so create a new key for each recipient device you want to update.

Note
You must be using a Raspberry Pi device running the latest version of Raspberry Pi OS (Trixie) to create the update. The recipient device must be a Raspberry Pi 4 or later.

To update a recipient device with an A/B boot configuration:

Step 1: Install rpi-image-gen
  1. On the Raspberry Pi, from the command line, run the following command to clone the rpi-image-gen repository from GitHub:

    $ git clone https://github.com/raspberrypi/rpi-image-gen.git
  2. Navigate to the cloned directory, then install the dependencies by running the following commands:

    $ cd rpi-image-gen
    $ sudo ./install_deps.sh
Step 2: Prepare and configure the image
Tip
rpi-image-gen contains an example application, with layers and configuration, to build an image compatible with remote updates.

For descriptions of the .yaml file metadata, see X environment metadata and Layer.

To prepare the image:

  1. Navigate to the rpi-image-gen installation folder

  2. Open examples/ota/layer/ota.yaml

  3. Customise the following metadata:

    • X-Env-Layer-Name.

    • X-Env-Layer-Category.

    • X-Env-Layer-Desc.

    • X-Env-Layer-Reqs.

  4. Open examples/ota/config/ota.yaml

  5. Set the following environment variables:

    • Version. Used to determine the version boot image. Set a starting version number now and increment it accordingly with each update artefact you create in the future. If you don’t specify a version number, it defaults to 1.0.0.

    • Device hostname. Used across all images created for this device. Must be unique. If you don’t specify a device hostname, the default value ota-device-1 is created for each build.

  6. (Optional) open examples/ota/config/ota.yaml and:

    • Define additional packages to install at build time. For more information, see Packages.

    • Add wireless networking credentials. For more information, see Wireless Networking.

Step 3: Generate an auth key

In this step, you create the auth key and copy it down for use in Step 4.

When you boot the recipient device after the A/B boot update (Step 6), it exchanges the auth key for an access token that is saved in the user data partition. This key persists across future updates, so you only have to generate it once.

For more information about creating auth keys for an organisation, see Create auth keys.

To generate the auth key:

  1. Log in to Raspberry Pi Connect

  2. Choose your organisation or Personal account from the account switcher at the top right.

  3. Go to the Provisioning tab (for an organisation) or the Settings tab (for Personal), then select New in the Auth keys section (organisation) or Create new auth key (Personal).

  4. Fill out the form, then select Create auth key.

  5. Copy down the key.

The Auth key view in Raspberry Pi Connect, showing an authorisation key ready to be copied and pasted
The Auth key page in Raspberry Pi Connect allows you to copy the key to the clipboard.
Step 4: Build the A/B boot configuration image

Now that you’ve set up the application and created an auth key, create the boot configuration image using rpi-image-gen.

This creates a .img file that will be written to the storage device with Raspberry Pi Imager in Step 5.

To build the A/B boot configuration image:

  1. From the command line, change directory to the rpi-image-gen folder.

    $ cd rpi-image-gen
  2. Run the following command, replacing rpuak_XXX with the auth key you copied in Step 3 (organisation auth keys start with rpoak_).

    Raspberry Pi 5 and later:

    $ ./rpi-image-gen build -S ./examples/ota/ -c ota.yaml -- IGconf_connect_authkey=rpuak_XXX

    Raspberry Pi 4:

    $ ./rpi-image-gen build -S ./examples/ota/ -c ota.yaml -- IGconf_device_layer=rpi4 IGconf_connect_authkey=rpuak_XXX

    The application generates the file and saves it in the /rpi-image-gen/work/image-x.x.x folder (where x.x.x corresponds to the version environment variable you set in Step 2).

Step 5: Write the image

Next, use Raspberry Pi Imager to create the operating system configuration and save it to the storage device.

Warning
In the example target below, (/dev/mmcblk0) is only used if you’re booting from another device, such as an NVMe SSD. Be careful not to overwrite the operating system.

To write the image:

  1. If Raspberry Pi Imager is not already installed, run the following from the command line:

    $ sudo apt install rpi-imager
  2. Open Raspberry Pi Imager from the Accessories menu in the graphical interface. Enter your password if prompted to.

  3. Select the recipient device type: Raspberry Pi 4 or Raspberry Pi 5, then select Next.

    Raspberry Pi Imager open, showing the device page with a range of Raspberry Pi devices you can select
    Raspberry Pi Imager is used to write the image.
  4. On the OS tab, scroll all the way to the bottom and select Use Custom.

  5. Navigate to the .img file you created in step 4, select it, then select Open.

  6. Select Next and choose the storage device to save the A/B boot configuration to.

  7. Select Write, then follow the on-screen prompts to complete the writing process.

  8. When Raspberry Pi Imager finishes writing the operating system, select Finish.

You can now safely remove the storage device in preparation for Step 6.

Step 6: Deploy the .img file to the recipient device
  1. Power off the recipient device.

  2. Attach the storage device from Step 5.

  3. Power the recipient device on, then wait for it to boot with the new image.

  4. Log in to Raspberry Pi Connect, then go to Devices.

    The device appears on the Raspberry Pi Connect dashboard and the Remote update label appears beneath the device.

The device is now ready to update remotely using Raspberry Pi Connect.

Step 7: Confirm the deployed version

Confirm the version of the deployed image on the device is the same as the one you configured in Step 2.

To confirm the deployed image version:

  1. Select the device in Raspberry Pi Connect.

  2. Select Connect.

  3. From the command line, enter:

    $ cat /etc/rpi-issue

    The command line returns something like the following:

    Generated using rpi-image-gen e3828f885c860f15991468883d3b8484b0eaf9d8 on 2025-12-09
    Artefact version: 1.0.0

Stage 2: Create update artefact

Now the device is configured for A/B booting, you can deploy update artefacts to it using Raspberry Pi Connect.

Update artefacts are created by rpi-image-gen as .tar.zst files. These are much smaller than the .img file you created in Stage 1, and are deployed in Stage 3 to the recipient device by Raspberry Pi Connect.

For the purposes of illustration, we continue to use the example update from Stage 1 here. Amend these procedures to reflect the path and naming of your own update .yaml file.

To build the update artefact:

Step 1: Update the ota.yaml configuration
  1. Increment the Version environment variable in the configuration ota.yaml file:

    ${EDITOR:-vi} ./examples/ota/config/ota.yaml
Step 2: Build the update
  1. From the terminal, build the update by running the following command:

    $ ./rpi-image-gen build -S ./examples/ota/ -c ota.yaml

Stage 3: Update remotely

Use Raspberry Pi Connect to deploy the update artefact to the recipient Raspberry Pi device.

Step 1: Deploy the artefact to the recipient device

Deploy the artefact from the Raspberry Pi Connect website, uploading the .tar.zst file you built in Stage 2, as described in Deploy the update artefact.

If the recipient device belongs to an organisation, host the artefact first, then deploy it using its URI and checksum, as described in Deploy remote updates in an organisation.

Step 2: Verify the update

When the deployment shows as Succeeded, connect to the recipient device using Raspberry Pi Connect and confirm the deployed version, as in Stage 1, Step 7:

$ cat /etc/rpi-issue

The command line returns something like the following, indicating that the Artefact version number has changed:

Generated using rpi-image-gen e3828f885c860f15991468883d3b8484b0eaf9d8 on 2025-12-09
Artefact version: 1.1.0

Enable remote shell at all times

Connect runs as a user-level service, not as root. As a result, Connect only works when your user account is currently logged in on your device. This can make your device unreachable if you reboot with automatic login disabled. To continue running Connect even when you aren’t logged into your device, enable user-lingering. Run the following command from your user account to enable user-lingering:

$ loginctl enable-linger
Tip
We recommend enabling user-lingering on all headless Raspberry Pi OS Lite setups to prevent your device from becoming unreachable after a remote reboot.

Update

Warning
Upgrading Connect disconnects any screen sharing or remote shell sessions in progress. We don’t recommended using remote shell to upgrade Connect unless you’re running commands in a way that’ll survive disconnection, for example, using screen or tmux.

To update to the latest version of Connect, run the following command:

$ sudo apt update
$ sudo apt install --only-upgrade rpi-connect

If you installed Connect Lite, replace rpi-connect with rpi-connect-lite in the above command.

Disconnect a device from Connect

Run the following command on your device to sign out of your Raspberry Pi ID, which will disable your device on the Connect screen:

$ rpi-connect signout

Alternatively, select the Connect icon in the menu bar and choose "Sign Out".

Tip
To fully remove a device from your Connect account, remove it from the Connect dashboard.

Uninstall

Run the following command to stop and remove Connect from a device:

$ sudo apt remove --purge rpi-connect
Tip
If you installed Connect Lite, replace rpi-connect with rpi-connect-lite in the above command.

After uninstalling, the serial number of the device remains linked with your Connect account. The device still appears in the Connect dashboard, but can’t be used for remote access. If you install Connect again, even with a different SD card, on the same device, it will reuse the existing device name in the Connect dashboard.

To sever the link between a device and a Connect account, remove the device from the list of devices in the Connect dashboard.

Troubleshooting

Known issues

  • Screen sharing only supports sharing a single, primary display of your Raspberry Pi. When a Raspberry Pi is connected to multiple HDMI screens, Connect sometimes shares the contents of the secondary screen. You can work around this by right-clicking the desktop and changing the location of the taskbar in Desktop Preferences…​.

  • Connect requires a browser that implements ECMAScript 2022 (ES13) as it makes use of features unavailable in older browsers.

  • Browsers intercept certain keys and key combinations. As a result, you can’t type these keys into your Connect window. Screen sharing includes a toolbar to simulate some of the most popular intercepted keys.

  • Upgrading rpi-connect and rpi-connect-lite using Connect’s remote shell is not supported. The upgrade process will terminate all remote shell sessions and drop all connections. To upgrade Connect in a remote shell session, use a tool like screen or tmux to ensure the process continues uninterrupted after your connection is closed.

  • To upgrade from version 1 to version 2, you must first upgrade the package you currently have installed before switching between rpi-connect and rpi-connect-lite. This ensures that Connect’s services properly migrate to the version 2 format. If you currently have rpi-connect installed, run the following command:

    $ sudo apt install --only-upgrade rpi-connect

    Alternatively, if you currently have rpi-connect-lite installed, run the following command:

    $ sudo apt install --only-upgrade rpi-connect-lite

    You see output similar to the following during the upgrade, indicating that Connect’s services have migrated to the version 2 format:

    Replacing globally-enabled rpi-connect services with user-enabled ones...

Common issues

Screen sharing not available

If Connect states that screen sharing is unavailable, one or more requirements for screen sharing support are not met. To help debug the problem, rpi-connect and rpi-connect-lite include the doctor command. Use rpi-connect doctor to identify issues with screen sharing.

Run the following command:

$ rpi-connect doctor

If all is well, you see output similar to the following:

Screen sharing is supported by this version of rpi-connect
✓ Wayland compositor available
✓ Screen sharing services enabled and active
✓ Communication with Raspberry Pi Connect WebSocket server
✓ Communication with Raspberry Pi Connect API
✓ Authentication with Raspberry Pi Connect API
✓ Peer-to-peer connection candidate via STUN
✓ Peer-to-peer connection candidate via TURN

If there is an issue, you will see something like so:

Screen sharing is supported by this version of rpi-connect
✓ Wayland compositor available
✗ Screen sharing services enabled and active - Please run rpi-connect on to enable and start all required services
✓ Communication with Raspberry Pi Connect WebSocket server
✓ Communication with Raspberry Pi Connect API
✓ Authentication with Raspberry Pi Connect API
✓ Peer-to-peer connection candidate via STUN
✓ Peer-to-peer connection candidate via TURN

✗ Some checks failed

If you have repeated issues trying to run Connect’s required services, run the following commands to check their status in more detail:

$ systemctl --user status rpi-connect-wayvnc.service
$ journalctl --follow --user-unit rpi-connect-wayvnc.service

If the service fails to start or doesn’t exist, ensure that your environment meets the following criteria:

  1. You use rpi-connect version 1.1.0 or later.

  2. You do not use rpi-connect-lite, which lacks screen sharing support.

  3. You use a Wayland compositor such as wayfire or labwc, not X. You can control this setting through the Advanced Options in raspi-config.

  4. You use a desktop environment supported by WayVNC, for example, Raspberry Pi Desktop. For instance, using KDE switches your Wayland compositor to kwin, which is unsupported.

  5. You have an active graphical desktop session running as the same user as the one you signed into. For most, this means enabling Desktop Autologin in the System Options in raspi-config.

Can’t connect after restarting or ending SSH session

Connect runs as a user-level service and is therefore only available if there is an active session for the user signed into the service. If you want remote shell access without also running another login session, enable user-lingering for your user, which will keep Connect running at all times.

For screen sharing, Connect can only share an existing graphical desktop session: it does not create entirely new sessions. There must already be a desktop session in progress. To start such a session automatically on boot, enable Desktop Autologin in the System Options in raspi-config.

Networking and firewall issues

Connect usually communicates between devices without requiring changes to your network or firewall. However, especially restrictive networks can sometimes block Connect communication. To help debug problems with such networks, rpi-connect and rpi-connect-lite include the rpi-connect doctor command. rpi-connect doctor runs a series of tests to check that Connect communication functions properly on your network.

To run these tests on your device, run the following command:

$ rpi-connect doctor

If Connect can communicate properly on your network, you see output similar to the following:

Screen sharing is supported by this version of rpi-connect
✓ Wayland compositor available
✓ Screen sharing services enabled and active
✓ Communication with Raspberry Pi Connect WebSocket server
✓ Communication with Raspberry Pi Connect API
✓ Authentication with Raspberry Pi Connect API
✓ Peer-to-peer connection candidate via STUN
✓ Peer-to-peer connection candidate via TURN

If Connect can’t communicate properly on your network, you’ll see an "x" instead of a check next to the failing test case. Ask your network administrator to enable the following connections on your network:

  • HTTPS requests to the Raspberry Pi Connect API and WebSocket server on port 443 of api.connect.raspberrypi.com and ws.connect.raspberrypi.com

  • requests to Raspberry Pi Connect STUN or TURN servers on UDP port 3478 of all of the following:

    • stun.raspberrypi.com

    • turn1.raspberrypi.com

    • turn2.raspberrypi.com

    • turn3.raspberrypi.com

  • requests to Raspberry Pi Connect TURN servers on TCP ports 3478 or 443 of all of the following:

    • turn1.raspberrypi.com

    • turn2.raspberrypi.com

    • turn3.raspberrypi.com

  • requests to Raspberry Pi Connect TURN servers on UDP ports 3478, 443, or 49152 → 65535 of all of the following:

    • turn1.raspberrypi.com

    • turn2.raspberrypi.com

    • turn3.raspberrypi.com

Remote update failures

If the A/B boot configuration or remote update process fails, refer to the following list of common faults and fixes.

You can also refer to the rpi-image-gen documentation and visit the Raspberry Pi Troubleshooting forum.

Tip

If you see an error, use Raspberry Pi Connect’s remote shell access to view the systemd journal for additional information:

$ journalctl
Error Suggested fix

Download could not connect to server (retry).

The recipient device must be able to locate the update file. Check that the device still has internet access.

For a device in an organisation, open a remote shell connection to the recipient device, then use curl to check whether the device can access the IP address contained in the URI you provided when creating the deployment.

$ curl -I http://192.168.0.1:8080

update file rejected.

Make sure that you deployed the .tar.zst update file, not the .img full image file. For a device in an organisation, check that the URI you provided when creating the deployment points at the .tar.zst file.

The deployment shows as Invalidated, with the reason File expired.

Connect keeps an artefact you upload for two hours, then deletes it. The recipient device didn’t start the deployment before that happened. Check that the device is online, then deploy the artefact again.

No Deploy option appears next to the device in Raspberry Pi Connect.

Enable OTA opt-in using the following command, then refresh your browser:

$ rpi-connect ota on

For a device in your personal account, also check that the device is online: Deploy only appears while Connect can reach the device.

View Connect status

To view the current status of the Connect service, run the following command:

$ rpi-connect status

The command displays output similar to the following:

Signed in: yes
Subscribed to events: yes
Screen sharing: allowed (0 sessions active)
Remote shell: allowed (0 sessions active)

The output of this command indicates whether or not you are currently signed in to Connect, as well as the remote services enabled on your Raspberry Pi.

If you see output including "Raspberry Pi Connect is not running, run rpi-connect on", run rpi-connect on to start Connect.

Enable enhanced logging

You can enable debug logging for both rpi-connect and its dedicated WayVNC server for a detailed account of local operations on your Raspberry Pi.

Enable enhanced logging in rpi-connect

Add the environment variable RPI_CONNECT_VERBOSE=1 to /etc/default/rpi-connect, and restart Connect with the following command:

$ rpi-connect restart

Alternatively, for versions prior to 2.7 override the rpi-connect service definition with the following command:

$ systemctl --user edit rpi-connect

Enter the following lines of configuration between the comments:

[Service]
ExecStart=
ExecStart=/usr/bin/rpi-connectd -socket %t/rpi-connect-wayvnc.sock -v
Note
You need both lines that begin with ExecStart=.

Finally, restart Connect with the following command:

$ rpi-connect restart

Enable enhanced logging in the dedicated wayvnc server

Override the rpi-connect-wayvnc service definition with the following command:

$ systemctl --user edit rpi-connect-wayvnc

Enter the following lines of configuration between the comments (including the -Ldebug flag):

[Service]
ExecStart=
ExecStart=/usr/bin/rpi-connect-env /usr/bin/wayvnc --config /etc/rpi-connect/wayvnc.config --render-cursor --unix-socket --socket=%t/rpi-connect-wayvnc-ctl.sock -Ldebug %t/rpi-connect-wayvnc.sock
Note
You need both lines that begin with ExecStart=.

Finally, restart Connect with the following command:

$ rpi-connect restart

View Connect logs

To view logs for the Connect service and its dedicated WayVNC server, run the following command:

$ journalctl --follow --user-unit rpi-connect.service --user-unit rpi-connect-wayvnc.service

Security

All connections between Raspberry Pi devices and the user’s browser use WebRTC: the same real-time communication technology used by Zoom, Microsoft Teams, and Google Meet.

End-to-end encryption

All screen sharing and remote shell access traffic is encrypted using DTLS between the Raspberry Pi device and the user’s browser. We don’t (and can’t) decrypt the traffic, ensuring your data remains private.

Every screen sharing and remote shell session uses a new WebRTC peer connection. For each connection, the Connect client on your Raspberry Pi device generates a fresh public and private key pair in memory, and your browser generates its own. The device never writes its private key to disk or sends it anywhere, and discards it when the session ends. The device and browser exchange their public keys and derive the keys that encrypt the session in a handshake directly between them, so our servers can’t derive those keys. The only key-related information that passes through our API is the fingerprint of each public certificate, which doesn’t allow decryption.

Everything in a session travels over this single encrypted channel: screen frames, keyboard and mouse input, clipboard data, remote shell input and output, and any credentials you enter during the session. None of this passes through our API. The API only exchanges the information needed to set up the connection, and receives device state such as whether the device is online, whether screen sharing is enabled, and the number of active sessions.

Furthermore, traffic is mostly peer-to-peer, meaning that the encrypted traffic doesn’t pass through our infrastructure. Instead, the encrypted traffic is sent directly between your Raspberry Pi device and your browser. This makes it impossible for us to observe it.

Relay servers

In situations where direct peer-to-peer connections aren’t possible (for example, due to networking issues), only encrypted data is relayed through one of our TURN servers. These servers are hosted in London and California. Only your device and your browser hold the keys to decrypt this data, and it’s neither logged nor stored.

Connect selects a relay for your device and for your browser separately, based on the continent of each one’s IP address. Devices and browsers in Europe and Africa use the relays in London; those in the Americas, Asia, and Oceania use the relay in California. If the location can’t be determined, London is used. If your device and browser are assigned different relays, the session can be relayed through either or both of them.

Connect has no setting to restrict which relays are used or to disable relaying. If you require direct peer-to-peer connections only, you can block traffic to the TURN servers listed in Networking and firewall issues. Connect then only works between devices and browsers that can reach each other directly.

Connection setup

The Raspberry Pi Connect API temporarily stores the WebRTC offer and answer required to negotiate a connection, including the IP addresses and ports of your device and browser. All traffic to this API is encrypted using HTTP over TLS, supporting only TLS 1.2 and newer for security. This ensures that connection information is never sent in the clear. This metadata is stored securely for at most 1 minute.

The offer from your browser is stored exactly as received and is never parsed or rewritten. Only the Connect web application, acting on behalf of a signed-in user, can create an offer; devices can’t.

A session can only be started by a user who is signed in with a Raspberry Pi ID that owns the device, or that belongs to the organisation that owns it, and who has authenticated with Raspberry Pi ID within the past hour.

Data retention

Connect retains only the metadata needed to operate the service.
