an update with the FIBARO KeyFob:
so far it works pretty well with SmartThings, at least while inside the network. i haven’t gone anywhere with it outside the house yet, so that remains to be tested. you can use it to control the status of SmartThings Smart Home Monitor, which is what I wanted to begin with.
just be warned, if you’re planning on using something like this with your SmartThings setup, the manual is quite dense (and doesn’t come in the box; it’s online) 💡
