Nest Learning Thermostat, 3rd Gen Polished Steel

Replaced my old mercury switch from the 60s with this and it has been great! Only needs 2 wires no C wire required. Google Customer Service helped me pick which thermostat would work with my Co-Op and this one is what they suggested. Only thing bad is linking it to Alexa is kinda of annoying. You need 2 Google Apps to link this. You first need the Nest App cause that is the only app that will link to this model. Then you need to link your Nest account with your Google Home app because they don't support Nest anymore, BUT still require Nest for Google home to communicate with the device. Only then can you use Google Home to link this to Alexa. One note with Alexa be sure to say, "Turn Off [room name]" if you have Smart Lights in the same room as the Thermostat. If you say "[room] off" Alexa thinks you are talking about the Thermostat and turns it off instead of the lights. Also one final note if you are going to use the feature where the Thermostat lowers the temp cause no one is in the house, be sure to link everyone's phone to your Nest and Home account. When we first set it up, only my phone was connected to the Nest and Home app and when I left for work my Girlfriend was unable to get the Thermostat to stay at temp cause it was convinced no one was in the house and wouldn't keep the heat on. Even if she told Alexa to turn it on, the Nest and Home app override Alexa's command cause it didn't detect my phone on the network. Aside from these bugs the Thermostat has been a great improvement to our home heating, we set a routine for the heat and just enjoy as the device handles the rest. A must have for any Home looking to save money on heat or to simply upgrade their home to a smart home! Only reason I would suggest not getting this device is if you have a C wire, if you do get a newer model so you only need the Google Home app to connect it.
