We are very technology afraid but we thought we would give it a try so we downloaded the app and it was so easy for us to use. We have friends who have the other type of thermostat that they use an app with and they have had many problems with it. I like our Honeywell and recommend it to others.
Not worth buying. For a little more money you can buy a thermostat that not only works but will provide more information. This one is supposed to show you the outside temperature but rarely works. It won’t show you the inside humidity level which we think is important.
