[OBSOLETE] Keenect V1.2.0, optional separate vo settings for cooling, vent obstruction auto clear

Dunno, I think you’re trying to over analyze the device type, I’m currently using the stock published ST DTH (device type), the one Keen says to replace, and I also used @yvesracine DTH, neither of them did anything like what you’re talking about with any of my vents.
I seriously doubt this has anything to do with the DTH.
