Hi Kendall - since you already had a thread open on the topic of Thermostats and how they work in SharpTools, I’ve merged your post in with that.
Side note: In general, if you have follow-up questions on the same topic, it’s best to keep them in the same thread. Some of the questions about functionality are already answered above and the search functionality of the community (or even google with “SharpTools [your query]”) can be helpful too.
Other threads in the community have screenshots of thermostat tiles, but I’m copying some fresh screenshots here for your convenience.
Thermostat Tile
Thermostats can be added in Single Height or Double Height layouts depending on what features they offer. The double height generally works best for thermostats like Ecobee where automatic modes (eg. ‘auto’ / ‘eco’) are used as it gives you visibility into the cooling and heating setpoints directly.
You can tap the ‘Adjust’ button in the bottom left corner of the thermostat to bring up additional controls for controlling the mode (and fan mode if your thermostat supports it). If your thermostat reports a different set of supported modes / fan modes, this UI can adapt to that.
In this example, I’m using a Honeywell thermostat which doesn’t offer an ‘eco’ mode.
As others have alluded to, the Thermostat interface exposes controls over features that are commonly implemented across thermostats. Things that are unique to a particular brand of thermostat, like which sensor is being used, aren’t exposed in the thermostat tile.
That being said, if your thermostat exposes those unique commands within its SmartThings integration, you could create a rule to use those commands. That being said, it feels like most thermostat manufacturers keep some of those unique features restricted to their app and expose just the core thermostat functionality in their smart home integrations. I can’t speak to what Ecobee exposes to SmartThings as I don’t use one.
