It takes a bit to get used to but once you do, it is very efficient. I like the way it averages among my rooms which keeps my whole house warmer when I’m there.
I would recommend this to a friend!

Works fine with an iPhone12. I could not get the thermostat to work remotely with my iPhone 6s. Had a persistent error message that I could not resolve

Very easy to install and has worked great. I just need to get more room sensors and then the whole house is good to go. It has definitely saved money on my hearing bill so far.

I purchased the T9 to control my cottage heat from my home. I have baseboard electric heat with a 2 wire 24 volt relay to control the 240 volt heaters. I knew this was non-standard but was hopefully the installation manual would provide some assistance.
Anyway, after about 12 hours of work, I got it working. There were several challenges to overcome.
First, I needed to install another transformer to power the "C" wire and get power to the new transformer (6 hours). Next, I had to figure out how best to connect the "C" wire and "Rc" wire to complete the circuit (2 hours research). Once I got the unit powered up I thought the rest would be simple. Unfortunately, the unit would not connect to my router. I called my internet service provider and they helped me change some settings to get 5G wireless working. It wouldn't connect to 2.4 MHz because i have an extender on my router using the 2.4 MHz (3 hours). I was lucky that my ISP is a local guy willing to help (not a big company with voice mail hell).
Finally, everything was powered up and connected. It took me 1 more hour to set everything up and understand the interface.
Anyway, I love it now that it is working and simple to use. But, setup on a non-stanard system is not easy and Honeywell provides no assistance.
