I like the thermostat. I had the wifi one that would geofence with the honeywell cloud. You could control it with honeywell's app. But a wifi thermostat can not integrated with HE. I wanted my thermostat to integrate with HE so I bought the T6 zwave and it was a direct fit to the existing base plate. Literally took 2 seconds to mount to the wall. My problem has since been resolved and the thermostat is working for both Fahrenheit and Celsius. I currently have it in Celsius. I am using the thermostat scheduler app that is native to HE. Definitely don't want manual control. Thermostat app is loaded with features and I use them all.
