I can be a bit neurotic about turning off lights when I leave a room, so Home Assistant was a nice way to free up brain space for me. A few motion sensors here and there + some simple automations, and the lights mostly handle themselves. Zigbee sensors and Zigbee or Matter-over-WiFi bulbs, so everything is local. A free VPS+WireGuard setup means I can access them remotely should I need to, with TailScale as a backup.
Cloud failures mean I can’t access remotely, but local control is unaffected—if my smart devices stop working it’s almost certainly my fault :)








What exactly is the incremental power draw for automation? My network gear and server (a little nuc) are sunk power costs as I self host other services.
Idling, my home uses around 100W with the fridge off. One 10W light is an additional 10% of my power budget, and I have a lot more than one light in my house. I also pay about $0.40/kWh.
