A while ago, I wanted to try Home Assistant. Then I realised that I didn't have a single thing to use it with. The locks are mechanical, the lights are simple LEDs, the irrigation system is manual, my car has push buttons, and I live in a safe enough area (by European standards) to not need doorbell or security cameras. Nothing I own depends on any external services other than the electric transformer down the street.
Never a better time to be a modern Luddite.
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 :)
Automating lights made sense 20+ years ago when lights were power hungry. But leaving on a 10w light bulb today is so meaniless. Especially after adding in all the power draw of the automation requires...
A single raspberry pi that draws maybe 3 watts, and fraction of a watt standby draw per device?
Also, 10w draw for a year is 87kWh. And you probably have more than just one light in your house.
