I’m really impressed with the breadth of devices homeassistant supports. It tracks the location of me & my wife via our iPhones. When we arrive at home after dark it turns on the exterior lights via zwave. We have 4 WiFi enabled ceiling fans from Big Ass Fans it can control, along with our Ecobee thermostats. Our washer & dryer use Insteon IOLinc modules to notify us when cycles are done. And in a few months we’re having a solar system & Powerwall installed, both of which have home assistant integrations as well.
