Home Automation Part 2
Back in October I talked about my growing, local Home Assistant setup, including some of my favorite custom automations. Three months on I’m still having fun with it. Recent automations include:
- Turning off the whole home’s water supply if a flood sensor triggers
- Turning on the north kitchen undercabinet lights when the south undercabinet lights are turned on
- Automatically turning off the christmas tree at 1am
- Polling a meshtastic node and alerting if it’s not
- Relaying meshtasting (LoRa) messages to my phone if I’m not home
I’m particularly happy with how that undercabinet lighting synchronization worked out. We have a galley kitchen and wall-switched undercabinet lights on both sides. We always use the ones on the south side with a conveniently located switch and seldom use the ones on the north side with the awkwardly placed switch. Now when we turn on one, the other turns on. That could have been done when it was wired 20 years ago, but now one Sonoff switch module in each switch, and it’s done over radio in a way no one has to think about.
More on those last two in an upcoming Meshtastic post, but all the nerds are playing with it now.
