OctoPrint-PiSupport 2025.7.23

Provides additional information about your Pi in the UI

Pi Support

The Pi Support plugin provides additional information about your Pi in the UI and also alerts you about undervoltage or overheating issues observed on your Pi or if your Pi is unsupported. If you are running OctoPi, the Pi Support plugin will also provide additional information about that.

OctoPrint will only load this plugin when it detects that it is being run on a Raspberry Pi.

This plugin was bundled right with OctoPrint's sources until version 1.6.0. It has been extracted into a standalone project to allow for a different release cycle, but is still considered a bundled plugin.

Setup

The plugin is part of the core dependencies of OctoPrint 1.6.0+ and will be installed automatically alongside it.

In case you want to manually install it into an older version for whatever reason, install via the bundled Plugin Manager or manually using this URL:

https://github.com/OctoPrint/OctoPrint-PiSupport/archive/main.zip

To install and/or rollback to a specific version <version>, either use this URL in the plugin manager:

https://github.com/OctoPrint/OctoPrint-PiSupport/archive/<version>.zip

or run

pip install OctoPrint-PiSupport==<version>

in your OctoPrint virtual environment, substituting <version> accordingly.
