Create an option that if the Smoke / CO2 listener detects an alarm, you can set the system to turn on all the lights in the house to assist with a quick escape. Alternatively, allow the listener to be visible to Alexa, similar to other sensors, so that a routine can be created to do the same.
I agree this is a must for safety!!!
Would be nice if I could program lights for other alarm conditions as well. (E.G. CO, breakin alarms)
