Windows and macOS have similar clients (Hass.Agent for Windows and Home Assistant for macOS).
I’ve found these kinds of clients useful because I can remotely wake-up or sleep computers, track how long they are turned on for, and automatically pause my lights and music when my webcam turns on.
This is so cool, first MQTT-based sensor I’ve set up. Already had a broker set up with HA, but how can HA automatically discover which topic to listen to, know the vendor name and how to interpret all the data?
