@jefo13, I’ve tried to outline the options for the Ecobee3 integration in the post below. There are several options. yvesracine’s code is the best way to access all aspects of your thermostat. I haven’t tested the most recent code, but it sounds like it’s mostly working.
StrykerSKS has been working hard on free Ecobee integration and it’s now live and works great (again, yves is not free, but has a lot more integration).
