I just got a few sets of fans and it down seem like the controller works. The fans have default lighting. When I open the app it says rpm is 0 for all groups. When I change the lighting the animation in the app would change but the fans are still stuck at the default color. I tried switching cables and controller but helps. Update: Uninstalling the lianli device in device manager worked for me cinema hd. Update 2: It stopped working after a restart and I can’t get it to work again.
