Poor technology set up for connecting to wi-fi...Other thermostats are much easier. It should populate automatically the available wi-fi connections for connection.
The T6 pro came with the house my wife and I purchased. Getting it transferred so we had access took multiple calls to Honeywell from the prior user. I understand you don't want unauthorized users controlling your thermostats but I have the code on the back of the thermostat and the random pin that only displayed on the screen. Set up was rather cumbersome and glitchy. Coming from having a Nest in my prior home made me aware just how much better that thermostat was. I would do your homework, compare comparable products, look at the features offered and the apps before making a decision to purchase this thermostat. Mine will probably be switched out within the next year.
