I'd love to test fan support. I assume I can refer to what you posted above and set it up myself? That is after searching for what I'm guessing is some sort of patch to try to keep the plugin authenticated...
I had a nice chat with an ecobee support engineer like 2 or more years ago asking for the simplest of things: add to their "run x minutes every hour" fan automation a "between the hours of x and x" option. Our fan needs to cycle the air in the house a few times while we're gone for the day at work/school, but NOT overnight when it wakes up the babies (or the wife...or the guests...now that the babies aren't such babies anymore.) The person was super enthusiastic and tripping all over themselves to thank me for the idea...and nothing ever happened.
so here we are, all this time later, trying to make the ecobee plugin do it in a timed fashion. So yes, I'd love to test it.
