Very user friendly. It is an additional perk that I can control the thermostats from my phone. I like the simplicity of the screen and the clarity of the presentation.
After many years of standard (non-wifi enabled) thermostats, I am thrilled to be able to manage our dual A/C units remotely. I can even manage them from outside the house to cool off the residence before arriving after being away.
It is easy to use and I love that I can set the temperature, from the app, to come on before I arrive home. Since each individual unit can be given a name, it's easy to know which unit you are turning on or off (just in case you meant to shut it off before you left).
Would've really appreciated if the thermostat had the timer option wherein you can enter the number of hours you would like the ac/heater to run before it switches off...
Usage log being delayed ~48 hours is terrible. I installed (2) T6 WiFi thermostats for a vacation property that is several hours away from my primary residence. In my application, I'd like to know how many hours the HVAC system has been running (or not). A 2 day delay in getting that information does not work for me. I'll be replacing the Resideo thermostats very soon.
Builder included this Honeywell T6 Pro Smart Thermostat in home purchase, I did not have a choice at the time. Following home purchase, however, I gave myself a few weeks of use and found I did not like the functionality and made switch to Ecobee, my preferred thermostat.
