I have 7 of these roller shades and the newest one I have is struggling to roll up. It's roughly one year old. The system is RadioRA2 and this shade is located in the bathroom (possibly humidity damage?) and it is the only shade that is triggered by a vacancy sensor as well (vacancy triggers lights off and shade up).


What happens is while it rolls down without issue, when it's triggered by the vacancy sensor or the pico remote it rolls up about 1" and stops, press pico button again and another 1", repeat this procedure until it reaches about halfway open and then it will roll all the way up.


Any ideas on where to start troubleshooting?
