Library for RF remote switches

I am trying this library on the elro wireless home control system (sold at action and various diy stores)

The remotes of this system have a HX2262 chip inside, so I figured it should work. The elro remotes have 8 buttons labeled on and of for devices A-D. Remotes and switches have a 5 bit system address, switches have an additional 4 switches to select A,B,C or D

There are also dimmers available for this system. pressing either of the on or off buttons toggles the light. Long pressing the on button cycles the brightness.

The actionswitch class works reasonably for this system. For dimmers, sending on and off signals work as they should. I think the dimming cycle should also be accessible if i'd play with the repeat length.

The switches however only work halfway. Switching the light ON works when sending an OFF signal, switching the light of does not work.

Any ideas?
