Can I use SmartThings Motion Sensors w an Ecobee3?

I am looking at buying an Ecobee3 thermostat. I already have SmartThings motion sensors which will report temperature. Can I use these instead of the Ecobee brand room sensors, to control the thermostat?

Also, on the flip side of that question. The Ecobee comes with a sensor, can I use that as an ST motion sensor, connected to my hub?

Yes, you can use any ST connected sensors and I have a smartapp to expose the ecobee’s remote sensors.

Please note of the following known issue with motion capability of the Ecobee’s remote sensors:

Refer to my thread for more details:


Thank you!

What app do you select from the store in order to use the smart things sensors with Ecobee and the Ecobee sensors with smart things. a little confused which once to buy, thanks.


See my answer here under the right thread:


Will “non” ecobee sensors show up on the EcoBee side of things? (HomeIQ) If not, what’s the difference from using ecobee vs a regular cheap z-wave connected therm?

No, it’s not possible to push data to HomeIQ through the ecobee APIs…

But, you still have the ecobee’s features, and my smartapps can leverage your ecobee’s comfort settings & ST ecosystem for better comfort and energy savings.
