Thanks so much, @bravenel for answering those key questions. Your responses made me wonder if my thermostat (Honeywell T6 Pro Zwave) is more capable, and therefore not a good candidate for using the thermostat controller app.
I'm using @bcopeland 's community driver (link to the HE Community page and Link to the driver code on github) which reveals most of the advanced (installer) setup functions.
Here's are screenshots of the advanced settings on the HE device page:
I read through the thermostat installer manual to go through the advanced set up as a fresh start and noticed the Auto Differential option. This seems to be a similar function as the control offset in the HE thermostat controller app.
Here is the text from the thermostat's manual:
With this in mind, if I change auto differential setting to 2 on the physical device and control offset setting to 2 on the controller app, will this cause any problems with either of them?
@bcopeland since you have (or had) this thermostat, do you use the "Thermostat Controller" app with the T6?
I'd like to use the app mainly for the remote sensor function since the thermostat only directly supports wired remote sensors.
@bravenel or @bcopeland - If I do use the thermostat controller app, can you confirm whether I should set the auto differential setting on the physical device tomatch the control offset setting in the virtual controller, or should I leave one of them at 0? My worry is if I set both of them to 2, I would cause the controller to over/under compensate the offset?
Once again, thanks so much for the help!
