Currently for me over the Summer i automatically have my ceiling fans come on via routines. But in the fall and winter when the outside tempature is cooler i do not wish to have them turn on. Could you set check in the routine that says if the Outdoor temp is say above 60F it would automatically turn on the fans?
You need a Rule Machine like CoRE, or Smart Rule Builder or something like that.
I do that with CORE as well as set the fan level (low,med,high) using my custom DTH.
