    Nice thermostat with cover plate

    There was a question on cover plates for the T9 in customer questions. Honeywell says THP2400A1027 cover plate will work. It works but you have to make it work. The THP2400A1027 will work, but you have to cut the raised corners off because the T9 thermostat doesn't sit flush onto the cover plate with these raised corners. They can be easily cut off with a sharp utility knife blade. After that you need to center the T9 wire back plate and drill holes for the THP2400A1027 to work and look good on the wall

    Great Thermostat with Multi Room Monitoring

    The T9 thermostat has been a great addition to my home. The main reason why I bought this was because our master bedroom would run hot because the thermostat is located in the kitchen next to a vent. This thermostat is capable of having sensors located in other rooms report back to the main tstat. I have a sleep schedule that uses the sensor located in the master bedroom. This way, at night, the thermostat caters to that sensor. Sleeping has become much more comfortable now. Only issue I've had was with install. I originally had a trane tstat and it is a special case when it came to wiring in the new unit. The T9 had me rewire it couple times (Error message during setup). Ultimately it worked fine, cooling and heat. I just had to change some wires around.Pros:Digital readout (turns blue for cooling, orange for heat and white for idle)Wifi/Alexa enabledMulti Room monitoringScheduling and geofence capabilities (home and away settings)Comes with C wire converterLearns when to cool/heat based off time it takes to reach desired tempDecent App (don't understand why other complain about it)Cons:Has to have a C wire(Blue wire if you have a trane tstat)Main tstat reports the temp of the sensor it is monitoring instead of main tstat all the time (should be able to switch between sensors)

    Extremely easy to install, works with combined 2.4 and 5Ghz wifi networks with simple trick

    Our home came with a "dumb" T6 thermostat. But being a newer Honeywell thermostat model, the backplate is the exact same as the one that came with this thermostat. So installation was literally pull the old face panel off, and snap this one on there, plug and play, 30 seconds job.Setup was incredibly easy too, the step by step setup on the screen is pretty intuitive. There were a lot of reviews saying if you have a mesh WiFi, or any system that's got the 2.4Ghz and 5Ghz band combined it would not work, and that worried me at first, because I want to have my device under one SSID, and I have several APs on my network.But the solution to that is actually very simple, I just found a old network extender, set the extender to connect to my home network, where it can read and connect to my main combined band WiFi, and then ask it to broadcast the extension network in 2.4Ghz mode only, under a different SSID. I then connect the thermostat to that extended network, and problem solved! It is still managed by the DHCP server on my main network, the thermostat never drops offline, and I keep my combined 2.4Ghz+5Ghz single SSID setup for the main WiFi. I used it like this for about a month now and had zero issues with connectivity. I agree this should not even be a problem to begin with in this day and age, but this workaround took me less than 10 minutes to get setup and running, and half the time was trying to reset my old network extender to factory settings...I did notice the humidity sensor is a bit off though, it reads high by about 10% compared to my other humidity sensors in the house, and those 3 are all in agreement +-2%. And it's not just the thermostat itself, I bought a separate room sensor for it afterwards, and that ones reads about 10% high too, so maybe it's just how they are calibrated by Honeywell? But anyways, that's not the reason why I got it to begin with so it doesn't matter much to me. Overall very happy about the thermostat, the only show stopper that worried me initially was the WiFi situation, and that turned out to not be a problem at all.
