Ok but sneaky version number
on August 17, 2025
Posted by: TheTl
from Canada
Verified Purchase:Yes
Looks OK but because of version one I can’t use other sensors with it. Kind of makes it obsolete except for heating the single room. A little disappointed there’s no literature that I could easily find that talks about the different versions of this product and how they work with other sensors that are supposed to work with it.
No, I would not recommend this to a friend.

Works for dual thermostat system
on August 18, 2025

I was having a hard time finding a HomeKit thermostat to replace my Control4 thermostat. I have a dual transformer system with gas boiler radiant heat as the primary heat, electric heat in the air handler as backup, and A/C. The thermostat was easy to set up and get connected with HomeKit.

T-9 is Great

How can a thermostat be this good?
If your HVAC system has been using the original cool OR heat mode, you are in for an amazing improvement. Once set up, it’s able to do its job without your fussing.
I do recommend using the remote thermostat for upstairs sleeping area. And of course, the wi-fi connectivity is great.
I would recommend this to a friend!

Multiple Sensor Functionality Is Great

Verified Purchase:Yes
I like being able to set the thermostat to monitor multiple temperature sensors and prioritize sensors at different times of the day. It's great to prioritize the bedroom at night, to ensure we have a cool night's sleep.

It's simple, and it works!

Verified Purchase:Yes
We installed the T9 thermostat in our house as part of a major remodeling project (our house was destroyed in a fire). It was easy to set up and connect to our Wifi, and it's been great to be able to adjust the settings on each floor of our house from our phone.
I would recommend this to a friend!
