Haha these ones are on a physical switch --- too many issues of people turning them off in the app, and then having someone else hit the switch. It's a temporary solution, thankfully
It would be a good prank, done lightheartedly. The dark side of automation is spooky!
In this case — I really pranked myself!
I also just learned that MagicHome devices send unsolicited messages to ALL devices with an active TCP connection to them. It's pretty cool, actually, and very fast!
Edit: Looks like that's just for power, though.
