HASS.Agent is completely free, and will always stay that way without restrictions.

However, developing and maintaining this tool (and everything that surrounds it) takes up a lot of time. Like most developers, I run on caffeïne - so a cup of coffee is always very much appreciated!

Why?

The main reason I built this is that I wanted to receive notifications on my PC, including images, and to quickly perform actions (e.g. to toggle a lamp). There weren't any software-based solutions for this, so I set out to build one myself.


Functionality

Summary of the core functions:

  • Notifications: receive notifications, show them using Windows builtin toast popups, and optionally attach images. Supports actionable notifications: add buttons so you can easily interact with Home Assistant, without having to open anything.

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

  • Sensors (currently 37): 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.

Installation

Installing HASS.Agent is easy; just download the latest installer, run it and you're done! The installer is signed and won't download or do weird stuff - it just places everything where it should, and launches with the right parameter.

After installing, the onboarding process will help you get everything configured, step by step. If you want an introduction into HASS.Agent, be sure to read the introduction docs.
