Awful horrible! Anytime someone's at the door and rings the doorbell the nest goes black an won't load. The nest thermostat always says ERROR will go a few days just fine then stops...an no its not a wiring issue or a wifi internet issue just glitches an has for the last year we've had it. Horrible products should have gone with Ring instead. So tired of being frustrated when I'm in bed an the house is freezing an I can't get the thermostat on the app to work/door bells rings and can't see who.
