A:AnswerThere are a few Honeywell smart thermostats, so without knowing which thermostat you have it's hard to say whether it is compatible with the Google Smart hubs. However, it will work any Google Smart hubs if your Honeywell smart thermostat is compatible with Google Home. You should refer to the thermostat's directions to determine its compatibility with Google Home.
A:AnswerNo. Nest Hub can only be connected to the internet wirelessly. There's no ethernet port for a wired connection. Also, the power input range for Nest Hub is 100V - 240V, 50/60 Hz.
