[System Bridge](https://system-bridge.timmo.dev) is an application that runs on your local machine to share system information via its API/WebSocket. You can also send commands to the device such as opening a URL or sending keyboard keypresses.
## Prerequisites
### Version
This integration requires System Bridge 3.1.1 and above. Any older version will not work.
### API Key
You will need your API key. This can be found following the documentation [here](https://system-bridge.timmo.dev/docs/running).
