Yes I can confirm to that. In my case I have a 2 zone system so the temperatures are fairly well kept so I don’t need to fine tube it with sensors. I do have a routine for one of our bedrooms reading the temperature of a ST motion sensor on a bedroom a bit far from the thermostat
(see pics).
Almost everything “smart” is cloud based nowadays. Even Smartthings itself won’t work without internet. These Honeywell thermostats retain their current programming even if the internet is down and can also be controlled manually.
