This is my second unit as the first one stopped having a radio signal about weeks after installation. The unit does have apparent issue with wifi reception as even the replacement unit had some initial issues maintaining connectivity. Finally it seems to be working.
Easy to install. Works great. Fit in with my other Honeywell thermostats. Had to contact Honeywell technical Services through the online chat to make an option change in the programming but worked out and was very helpful.
Seem fine have needed to use much for either heat or cooling since installation. Contractor installed with a new heat pump. Contractor had difficulty with setting up wifi connectivity, but was able to set up once out of contractor mode myself. The jury is still out and may increase my rating later.
I bought the T6 Pro to do IFTTT with my MyQ garage door opener, I set the unit up to use with my garage heater which works fine. I wanted to set up a IFTTT applet to have the thermostat go off when my garage door is open, but all I could do is have it go down to the lowest setting of 4.5 C which would be alright but when you have -20 C weather and shoveling the driveway you don’t want to heat the neighborhood. I tried to contact Honeywell customer service, which ended up in U.K. They directed me to Honeywell in North America phone number, in which directed me to Resideo. That ended up in a dead end, and even trying on the website that just got worse. If you are looking for a unit to use for IFTTT, look else where. For a normal basic smart thermostat it works fine.
