I'm wondering if adding a simple 12v relay and connecting one side to terminals A & B of the bell output (Permanent +ve & Switched -ve) I could then use the other side to interface with the TuyaSmart device? Any thoughts'd be helpful.
Thanks.
Have been searching all day for something I can connect to a vanilla alarm panel that can send a notification to a mobile device.
I know I could use a GSM dialler of some description that taps into the -ve of the bell wire that can send a text, however, I was hoping for something that doesn't...
