I am having the same issue as Morty_Said. Version 1.0 for both parts, LEDs working as expected, air unit is powered by 9 volts. After updating both the air unit and controller I am unable to get them to pair.
I tried doing several reflashes, even tried 2 other air units and have the same issues. Also did a complete reset of the controller.
Is there a utility of some sort I can use to roll back the firmware?
