made a doorbell out of one of them
Has it been reliable over time? I tried using one to turn on the heater in my camper, which worked maybe 70% of the time… The hack to get them to work, at least when I was fiddling with them a couple of years ago, was so hackey (detecting when the device joined the wifi network), it just didn’t seem reliable enough for anything that absolutely had to work like a doorbell. I’d be curious what your experience is though, since I’ve still got like 5 of them, which have suddenly been elevated to interesting old tech.
