User interface 10/10 App 8/10 Installation 6/10 Probably biggest issue is that your old Thermostat moat likely won't have any COMMON wire. The Nest website won't mention it in detail, but it seems to be the main reason why you will get an E80 error. A missing wire can be difficult, but try to use the FAN wire as a COMMON. On most systems installed in the last 15 years, the fan wire is not used.. Else it's a great product, well packed, good instructions and functions as describes. Pretty cool product
