Works like a charm!
This is a really neat device. The only issue is that 1) you have to scan the big paper QR code with the device name for it to work, not the QR code on the device 2) the supplied screws are just too long. I replaced it with screws from my spare parts bucket. Haven’t had a chance to test notifications yet but I’m sure that’s not going to be a problem. Addressing the 1-star review here: read my n.1 point above, that fixes it.
