Syncthing is a continuous file synchronization program. It synchronizes files between two or more computers in real-time, safely protected from prying eyes.

The Syncthing integration allows you to monitor states of your synced folders from within Home Assistant and set up automations based on the information.


To set up the monitoring you need to get an API key. Open the Syncthing web interface(e.g., in the browser and go to Actions -> Settings. You will find the key on the right of the settings dialog.


Adding Syncthing to your Home Assistant instance can be done via the user interface, by using this My button:
