Shelly RGBW2 White Color and Brightness control inverted

Hi , I have installed shellyForHASS and everything works fine except the Shelly RGBW2 that has brightenss and color inverted.
I use the shelly to control a simple white led strip connected on the W pin of the shelly RGBW2. I switch on and off the leds by another shelly1.
Always works correctly with the exception of brightness control.
Any idea
