My wife and I absolutely love the T9 Thermostst. Once set up it's very easy to use and set up. We also got one remote sensor and it's in our living room. We have it set as the primary because it gets hotter in there in the Florida summer. Our electric bill has gone down more than we thought it would so yes it's worth the money and we are very happy with it.

We have two other resideo thermostats, but this one has vents in two rooms, the Guest room has the thermostat, the gym doesn't. We found we needed a sensor in the gym for better control of the cooling /heating pricess.

A great improvement over most basic “old school” type home thermostats. Having remote control to adjust temperature when out of home is quite a convenience and helps manage energy usage!

We were replacing older thermostats with T9s for the connected capability. Remote monitoring, etc. The thermostats were easy to install and connect to the network. Instructions were clear. Setting up a schedule is not hard - but the app makes you do each step manually so it takes awhile if you have a moderately complex schedule. Copy and paste would be nice.... I'd also like to be able to copy schedules from one thermostat to another.

Looks great and overall works well but keep losing it on app and have redo load it and restart thermostats then it says on app that it’s already registered and not able to use it on the app as it’s not there

Great thermostat- got it to replace an older Honeywell model (t4 pro series) in our home. Easy install and setup and it works perfectly. I’m leaving 4 stars, however, as although the T4 and T9 are compatible with wiring, the wall plate is different and the new T9 sits awkwardly on the wall plate. No new wall plate included with the thermostat and none available for sale anywhere…. So fantastic function, but doesn’t look great on the wall….
