Hi @all4dom
The stock DTH exposes only about 10% of the ecobee APIs… I expose more than 80% of the APIs.
With My Ecobee device, you can use any ST connected temp/motion sensors to adjust the thermostat setpoints (similar to the ecobee’s follow me feature).
And, there are many complimentary smartapps at my github (for the most common use cases):
See this thread for more details:
And, the ST community wiki:

If you want to specify which ST motion/temp sensors to be used at a specific time of the day (according to your ecobee schedule), I’d recommend My Ecobee Bundle which includes the ecobeeSetZoneWIthSchedule smartapp (based on the concepts of rooms/zones/schedules).
