First, thank you for adding support for Flair. I am receiving data from both the puck and the vent, however,  the vent is not responding to any commands from the ISY. Currently the vent is open (showing 99% in the ISY). If I set the position in the ISY to 0%, in about 10 seconds the value in the ISY jumps to a random value, then a few seconds later it jumps back to 99%. The vent itself never makes any changes. PM'd you a debug log.

I’m able to control my Flair vents with ISY using Nodelnk.
