Just to let people know, Smartthings is wrongly reporting the First Alert Smoke / Carbon detector. Mine was saying connected with 73 percent battery, but found out that it was not connected and the batteries were dead.
Yup, but it’s not an ST issue. I had 11 of those things and got rid of them because battery warning alerts started at around 78% and then quickly died. These detectors don’t have good battery life in my opinion, and I wish FA had a wired and interconnected version.
They are reportedly coming out with hard wired version this Spring
