I am new to SmartThings and I’m having a hard time getting some ZigBee devices to work. I tried every possible existing device available and none worked. I did my best to make sure this device hasn’t been asked about and the closest I found is something for the MCT-320 l, which is different. The MCT-302 a wired to wireless contact, essentially just for an open/close function.
Again I am new but can anyone outside of developers build the handler for a device? I have a siren that doesn’t work either, both of these devices pair in as “unknown”.
