After about a year, my Nest Protects just started losing network connections, requiring a physical uninstall, followed by a factory reset, followed by a new setup, and finally a physical reinstall. I've contacted support, but they only provide copy/paste responses - no actual solutions. And Google won't take the return for the 5 detectors that are now just expensive "dumb" detectors.
If you get a Nest Protect, either make your peace with the fact that these devices are not reliably network compatible, or assume you will be on a ladder at least once a year hard-restarting/re-initializing it. And if you have more than one in your home, multiply that effort by the number of detectors.
I'm really bummed about this - I thought Nest Protect would be a great product. Turns out, it's nothing but trouble.
