Hard to adjust the schedule and can’t make a copy of the schedule for multiple days
No, I would not recommend this to a friend.

Great thermostat- connectivity challenges
on December 10, 2025

All was great except for the problems hooking up WiFi connectivity. I had to spend a lot of time on the phone with support, and they were also stumped at one point. We finally changed to a different program in order to make things work.

Smart Thermostat at Its best

This is the 4th house that I have installed a Honeywell smart Thermostat but first time using the T9. I love the easy install and setup. Gives you everything you need even if your missing the C wire.

Thoughts on T9 Thermostat and Resideo App
on December 5, 2025
Posted by: Anonymous10
Verified Purchase:Yes
I switched to the T9 from Nest. The thermostat was easy to install and seems to function well. The Resideo app is slightly less impressive than my previous Nest experience. I felt like I had more detailed control, especially regarding scheduling, in the Nest app. Additionally, the "Runtime" information was much more detailed and accurate in the Nest app. Overall, the Nest app seemed more "user friendly", but the Resideo still offers most (but not all) of the functionality I previously had.
I would recommend this to a friend!
