Hello @Roach,
You may want to look into this thread first:
As specified earlier in the above thread: ecobee motion sensors don’t allow real-time events.
Also, on the ST side,there are some rate limiting and max execution time constraints to take into account which is why the polling interval cannot be lower than 10 minutes.
You can refer to ecobee API documentation:
https://www.ecobee.com/home/developer/api/documentation/v1/objects/RemoteSensor.shtml
Which states (about motion occupancy):
The remote sensor data will only show computed occupancy, as does the thermostat. Definition - For a given sensor, computed occupancy means a sensor is occupied if any motion was detected in the past 30 minutes.
So, I’m sorry but there are limitations in the way the remote sensors were designed, and they will never be like any ST motion sensors (unless ecobee makes some serious changes on their side).
But, you may want to contact ecobee support if your remote sensors are still reporting occupancy after more than 1/2 hour…Please check at your physical thermostat first.
Regards.
