Run Your Home on a Raspberry Pi
Home Assistant[1] is the best approach I've found for this. It's pretty amazing but has a pretty steep learning curve (although they're getting better and better at this). The real power of HA is the rich integration ecosystem[2], the Community Store[3], and that it runs locally (more reliable and much faster for things like motion sensors, etc).It expresses everything from every integration as an entity in various device classes so as long as some random tech is supported by an integration you can group them seamlessly. For example - I have Z-wave based motion detectors but I can control Hue lights and Wemo switches for motion detection - but only if I'm home as reported by the zone feature in their iOS companion application.Their supervisor/docker based install for Raspberry Pi is pretty slick[4]. Write an image to disk as you usually would and you get a bare-bones OS with Home Assistant running in docker. Then there are additional docker-based add-ons you can install for stuff like MQTT, Z-Wave, Let's Encrypt, SSH access, nginx, and more. All managed in the web ui. Pretty cool.[1] https://www.home-assistant.io/[2] https://www.home-assistant.io/integrations/[3] https://hacs.xyz/[4] https://www.home-assistant.io/installation/raspberrypi
