Ordered Nest as first choice but no go as i had multistage HE furnace (Carrier Infinity) and only Eco bee will work.
Happy with Eco bee and hooked it up to google home too in a minute.
Wanted to keep old thermostat but they were very sticky and said couldn't and had to take the one on there and working with furnace now. I had older one that i wanted to give but no go. They were going to just walk out. I said i'll install the older one on but they had no time. They were nice enough to come back in 30 min but i couldn't get the old old one working as not Mulit Stage compatible. They gave me a hard time and said even though fan worked it didn't kick in the multi stage so NO GO.... pleaded and he did alternative test to test furnace ok with that thermostat and he let let it go... So moral is change any older thermostat before hand or else they may just walk away.
This is just a novelty i think and will prob not save any money in the long run.... but hell, it's free so why not.
For Google home you can say "what is the temperature in the house", "set temperature to 23 degrees" or you can use app and wifi to control it too.
Remember this is the Eco Bee Lite so NO ALEXA built in nor free sensors.. But no biggy.
