I have a question about smoke alarms. I don't know a lot about smoke alarms and I want to make sure I get it right before I even attempt to make my smokes smart.
My smokes are currently only connected to the main breaker and each other. I have 3 and each has 3 wires (red, black, white). The black & white are for power and the reds are connected to each other for interconnectivity communication between the 3 smokes.
Can I add a relay to the last smoke and have that trigger on the Konnected board?
