Good standalone product; poor API/extensibility

The product is very good in standalone mode, but I am still waiting my Resideo Developer access for integrating the T9+ in my Home Assistant environment. Resideo Developer access should be granted in less than 2 weeks and we are way over that now.

T9 Thermostat

As a first time user of a WIFI enabled thermostat I will give it a solid 4 stars. I am just now getting into the whole electronic home idea and so far I am liking it. Hard to believe but I just got internet in my home and this was the first thing added. Not much to say currently other than this.

Game Changer!

The smart thermostat paired with smart sensors has been a huge upgrade for our home. We have a single zone steam boiler and our daughters room used to run cold. We added a smart sensor in her room and are able to prioritize her room at night.
No, I would not recommend this to a friend.

Thermo is difficult to use with the touchpad and the remote is worthless. Hope I can return it.
