Thermostat works well and is aesthetically pleasing. The phone app is a little cumbersome with options and settings located in unintuitive places which takes getting used to.
Easy to install and great to use! I had an unsuccessful experience with another brand, and then chose the T9 and am delighted. LOVE the functionality of it; and, really appreciated the additional room monitor to independently confirm temps!
Basic smart thermostat with potential, I've had this thermostat for several years now hoping Honeywell would update the firmware. The updates have not come, there is still a 48-hour delay to see usage. A nest I can view usage instantly throughout the day. A monthly review is sent out, but only after about 3 weeks late. There are no options to allow the fan to blow after he or cool are turned off to add a little more efficiency to the system. After having a Nest at my new house for a month, I really appreciate what they were trying to do. Another problem is during setup when you're trying to test to make sure you have everything hooked up properly, it boots up and says waiting for equipment, there needs to be a countdown timer after boot up and something on the line during boot up timer or something along those lines. This thermostat has so much potential but Honeywell has not listen to any of my feedback.
