It's easy to use and I love the bigger numbers and the larger font, it's easy to see. The app is wonderful and easy to use. I love that I can set my thermostat from my phone so I don't have to come home to a hot or cold home. Getting an energy credit for going smart also sweetened the deal.
Programming is not very user friendly, and a bit confusing when it comes to automatically changing back and forth from AC to heat (as needed during shoulder periods).
read lots of bad reviews prior to using this thermostat. It came with a new HVAC install of which the HVAC tech installed. You need to know a little about HVAC if installing yourself. The wifi setup was easy. Setting up a schedule was easy. My only negative comment is the 2 day delay in runtime stats on the App. This product does exactly what it's supposed to do
I've only been using the T6 Thermostat for about a month and so far it's working well. At the moment, I'm only using it for heating as I don't yet have an air conditioner installed (hopefully that will be added next year). I haven't yet explored all the functions of the Resideo app, but do have a basic schedule set. Changing settings either from my phone or the thermostat is very easy.
