Yes, both the app and browser interface are working fine. I guess my
question relates to where the temp setting limits used by Google Home
originate. The source isn't from the thermostat configuration, best I
can tell.
This Honeywell Thermostat model is th6320wf1005. There's no upper limit
parameter for cool mode and no lower limit parameter for heat mode as
far as I know (parameters 27/28).
