Haven't heard from Ecobee, which tells me a lot about their customer service. If you buy Ecobee thermostat and it doesn't work, don't expect them to help you. You will end up like me, wasted all that money and time!
And my new Nest is working great! Should have bought it in a first place.
I will keep you updated on any progress or no progress more likely. Just want to make sure that no one will have the same bad experience with the Ecobee!
