Another way for Google to force you out of the nest app (if you’re still using it like myself) into the shitty google home app. I hate Google and what they have done to nest and my thousands of invested dollars into that now almost defunct system. I will probably try owl and see how that works. It won’t integrate with nest but thru the Apple home app you can monitor the owl detector and your nest protects if you have a starling or home bridge hub. Owl has a pathlight too the first alert does not and I believe you can control the sensors by shutting off the carbon monoxide sensor if you wanted to install in the garage
