Love the look and features but the app is a little buggie. I keep asking me to set ut up and "welcoming" me to my "new" thermostat wven after a dmfew months of use.
This has made a huge improvement in the comfort of my home. I have a three zone system and was able to very easily install these thermostats. My house now actually stays at the temperature the thermostat claims it's set to. The remote sensor is a complete game changer. My daughter's room is on the far end of the house and runs cooler in the winter. I am able to target her room at night and keep it at a reasonable temperature that couldn't be achieved before with just my main system. 10/10 recommend
I had some difficulty with the installation to an old gas boiler but the technical two support advisors were excellent in guiding me through the installation. I needed to install a transformer on the boiler for the 24 volt power supply needed for the thermostat and they provided specific model numbers for it.
