Getting Started


This page explains the basics behind HASS.Agent: What it is and what it can do. We'll be using the abbreviation HA for Home Assistant, so when HA is mentioned, it refers to your Home Assistant instance.

Getting started Video

EverythingSmartHome's youtube video is a great guide to get you started: Control Your Windows PC With Home Assistant!. Note that it is based on an older version(v1), so for instance the mentioned missing 'actionable notifications' are already implemented.


In general, HASS.Agent is a client (companion) application for Home Assistant. It's being developed for Windows, with Windows 10 and 11 (fully up-to-date) in mind - previous versions or unpatched systems may work.

The communication goes both ways: HASS.Agent can send data to HA, and HA can send data to HASS.Agent. In other words: you can use HASS.Agent to control and inform HA, and you can use HA to control HASS.Agent.
