Ecobee 3 fan endoint to use in CoRE

Hi community
I am sure I am not the only one with that use case but I cannot find what I need so far.
I have an Ecobee 3 thermostat and want my smarthing to turn on the thermostat if there is a more than 3 degrees delta between my 1st and 3rd floor. I am using Core for this and the rule is really straightforward but when selecting a Thermostat Fan Mode capability in my action list, my Ecobee3 is not listed here, therefor I cannot set my fan to on or auto from CoRE.
Did I miss something ? I am using the official Ecobee 3 integration in SM. Every alternative integration I tried failed (same result in the end).
Thanks for your assistance.

Use the Thermostat capability. The Ecobee does not define the Thermostat Fan Mode capability, they’re all crammed into Thermostat anyway…

Damn it ! I knew I was missing something ! I was just biased by this Thermostat Fan Mode capability…

Thank you very much
