Awful, useless thermostat!
on December 16, 2023
Posted by: Gilggy

Verified Purchase:Yes
Constantly goes into registration mode. Disconnecting, and resetting to factory defaults doesn’t help. The iOS app can’t connect to the thermostat, and repeatedly displays registration error.
No, I would not recommend this to a friend.

Great thermostat but does not have a humidity control. You have to adjust the temperature cooler to lower the humidity.

Please make this device not require internet

Verified Purchase:Yes
While the device is nice it requires internet to work properly with the app. It would be good if the device and app could manage independently of the internet.
No, I would not recommend this to a friend.

Honeywell T9 smart thermostat
on December 20, 2023
Posted by: Thatdude
from Illinois
Verified Purchase:Yes
Great product however after a month it randomly cuts off and reboots itself, when I first experienced it, I figured well it’s probably rebooting from a update or something, however it does it randomly and will stay with a blank screen for about 1 1/2 mins and you will hear it click and the welcome sign boots back on. I check all my connections and there all good which lies on a possible faulty T9 or are they all like this
No, I would not recommend this to a friend.

Simple issue makes this a waste of money
on December 20, 2023
Posted by: B Rice
from Fort Worth, TX
Verified Purchase:Yes
Great for setting up programs but useless for the main reason I purchased it. With it connected to WiFi, the time is set by their network and therefore cannot be adjusted even though it is off by 5 hours. That means that all of the schedules you create are wrong and is a pain. The only fix is to leave the network connection off so you can change the time to align with your time zone. Not being able to connect to it remotely and make changes means it is no longer a "Smart Device". Others have reported similar problems.
No, I would not recommend this to a friend.

Great for zoned radiant heating system
on December 21, 2023
Posted by: LWSx
from Sunset, SC
Verified Purchase:Yes
I had 4 of these professionally installed to an existing zoned radiant floor heating system. The installer completed the job readily and setup, including the app, was very easy. We love the ability to remotely adjust our preference and they are managing the zone differentials very comfortably .
I would recommend this to a friend!
