Helps with uneven heating
This thermostat with the remote sensor solved the issue we have in our home with every room being a different temperature. We installed the remote sensor in the coldest room (bedroom above the garage) and programmed the thermostat to read from that when we go to bed. The house is much more comfortable now. Installation was the same as any thermostat but we had a C-wire already so didn't need the adapter. Set up and programming was very easy. The app was tricky to install but I like the security, just wish it had a better design. I love the fact that you don't need a smart hub to connect and control this thermostat, all you need is WiFi and a smartphone. Controlling the thermostat remotely is a plus too. The price is a little steep but overall I'm happy with the purchase. I'd like to use more sensors but those too are expensive. If you don't have a need for the remote sensors there are cheaper thermostat options for you.

Great smart thermostart
Very straight forward to setup and easy to use. The app works well and has all the features you can access on the thermostart itself.

T9 Smart Thermostat
Easy to install and set the programming. But if I need a temporary change, I just pull the app up on my phone from anywhere in the house and change the temperature to whatever I want. Holds it until I change it again or until it changes to the next cycle of preprogrammed settings. Very handy and efficient. I don’t have to remember to change my thermostat to a cooler setting for sleeping, it does it automatically.

Nice but awkward-sized thermostat
The thermostat is intuitive and easy to program. The background changes color to let you know the furnace or A/C is running. I’m happy with it except for the footprint. It is taller and shorter than older thermostats and doesn’t have wall plate. I’m now stuck trying to color match a custom paint job - base and faux finish :(

Godd but not Mysa
It’s working well. You need a wire C or an external power supply 24VAC 500 mA. It’s not Mysa but close. Consommation details are really basic. Just number of hour work during the day. I wish we have details like temperature on graph by hours.

Awsome product
Awsome product! We had and it older Honeywell thermostat that I installed in our old home but we left it there when we moved. We wished we had brought it with us until we bought this T9 and installed it. The T9 is better in every way from our older one. We use the wireless room sensor at night to have the HVAC maintain a good temp in our infants room for sleeping. Only thing I would change is I would write on the box that I’m big letters that it comes with the c-wire adapter. I didn’t see it so I was getting ready to install new wire and when a few hidden staples made it difficult I dug through the box and saw the adapter.

Great Product!
The Honeywell T9 works great and the remote temperature sensor eliminated the need to relocate the thermostat to a more suitable location. Note - The T9 is a vertical design that does not cover the outline of older thermostats so Honeywell has a plate kit (THP2400A1080) that works perfectly to cover the old paint outline, etc.
