OK, this is awesome too. I installed the Hubitat Safety Monitor (HSM) app and it found my Z-wave smoke alarms (ZCOMBO), flood alarms, doors, motion etc. I didn't want to mess with it too much so I just asked it to report to my Google speakers for testing.
However, this morning I got a message on my phone that Smoke was detected! My wife had left the turkey patties on without the stove fan on so it was minor but legit. I had done nothing except install the Hubitat Android App and the HSM app and I got this! Very cool Hubitat.
