Question
Jeroen_ 20
Hi There,
I would like to add my existing smoke alarm to my smart home. The situation is that we have a smoke detector on each floor (3 in total) and these are all powered by 230V AC. Each unit has a battery back-up. The units are also connected with an extra wire which is used to trigger the alarm in the other units when 1 unit detects smoke. The current on the wire is normally 0V DC, but when the detector is triggered there is a 10V DC current. I would like to connect a smart implant which triggers my HA system in case of smoke (potentially fire). For example, to open all the blinds immediately.
I have a smart implant and a 12V power supply, but I'm not sure how to connect the sensor. Is it as simple as connecting the 12V from the power supply to P, the ground from the power supply to GND and the wire from the smoke detector to in1 or in2? Can the smart implant give me feedback about the measured DC current on the in1 or in 2 port? For me, the manual is not clear about my situation.
Thanks,
Jeroen
