The app could be a little more robust. I like how it tells me how much heating and cooling is done, but it doesn't estimate how many kilowatt hours it's used to get there. I think that would be a good feature to add in the future to make it easier to estimate heating and cooling costs based on usage.
My HVAC company gave me the wrong model numbers. I have since changed eight track companies and moved to the ecobee. The Honeywell model did not have the ability to control humidity.
Love having a Wi-Fi thermostat in the house. It gives great peace of mine while we're away. The display is easy to read and even easier to use. Having the Resideo Thermostat App on my phone is super convenient. I'm very happy with the value. I look forward to a comfortable summer, thanks to this thermostat and the new A/C and Furnace in our home.
