We add this with our new HVAC and find it works well. Having Wi-Fi access to make adjustments is helpful. It is new to me and I am still learning the Wi-Fi options. The in home thermostat works great. I hope to expand the use of options in the near future. Video's online are helpful for how to use.
Our HVAC technician installed our thermostat and setting up the interface was simple. This process made the use of this thermostat really simple and so much more convenient than a traditional programmable device.
Directions online are poor for setup. Also, does not do both heat and cooling on the same day. Also, the app says it will send temp alerts but I have not been able to figure it out. Geez!
