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.
Been using this for several months now and it’s been great. I even set up scripts to set my next boot to be Windows when I know I’ll be gaming with friends using a game on GamePass so it’ll be booted and ready when game night is about to start.
