Doesn’t connect to WiFi as easily as it should, at first. Sometimes hard to read unless you touch the screen. Functionality is ok but overall slightly behind many of the other smart thermostats around today. The positive is that it I’ve been told it encounters Less issues than many other similar ones. I guess I’ll have to find out soon enough.
Very fine product with one glaring fault. I replaced my T-5 after it got zapped in a power surge with the newer T-6. I loved my T-5! The T-6 lights up our whole bedroom at night even when on it's lowest level. I took it out of my bedroom and installed it in a playroom where no one sleeps. I bought another T-5 and am now very happy!
I have two thermostats, upstairs and downstairs. They are efficient and easy to work. One problem I have is one or the other occasionally go off line and I have to reinstall.
