So far, I am satisfied with the performance of the T9 Smart Thermostat. It responses to the imputed settings. Easy to schedule the preferred temperature day by day or weekly. I recommend it.

Great thermostat and works well w/ automation!

Great product and easy setup! Works great with my Control4 automation and Apple HomeKit. Has a nice small profile. The Resideo app is also nice. My only gripe would be the display which I knocked off a star for. Too bright at night when on its dimmest setting. My suggestion for future product versions would be a better quality screen with more dimming adjustments/ capabilities. Those putting this in their bedroom would probably want to set the display to off when it’s goes to sleep. Mine is in the Living area so not a dealbreaker there. Overall great product and highly recommend for those looking to upgrade an old thermostat or wanting to add into their automation.
I would recommend this to a friend!
