Functionality

Summary of the core functions:

  • Notifications: receive notifications, show them using Windows builtin toast popups, and optionally attach images.
  • Media Player: use HASS.Agent as a mediaplayer device: see and control what’s playing and send text-to-speech.

  • Quick Actions: use a keyboard shortcut to quickly pull up a command interface, through which you can control Home Assistant entities - or, assign a keyboard shortcut to individual Quick Actions for even faster triggering.

  • Commands (currently 21): control your PC (or other Windows based device) through Home Assistant using custom- or built-in commands.

  • Sensors (currently 29): send your PC’s sensors to Home Assistant to monitor every aspect of your device.

  • WebView: quickly show any website, anywhere - no browser required, for instance a HA dashboard.

  • Satellite Service: use the service to collect sensordata and execute commands, even when you’re not logged in.

  • All entities are dynamically acquired from your Home Assistant instance.

  • Commands and sensors are automatically added to your Home Assistant instance.
