RFXCom and rollershutter using lighting 2 command

Is anyone using Chacon 54754 roller modules? They use lighting2 protocol, and the commands are identical to the light modules: On and Off commands (rather than Up / Down). If the On / Off command is sent a second time while the roller is moving, then it will become a stop.
So as long as I declare them as “switch”, they can be controlled correctly. If I declare them as RollerShutter, I see an error in the logs: “can’t convert Down to command”. Any idea on a solution for this to work as rollershutter?

The binding has to be adapted to support this, you could raise an issue in the issue tracker. Provide as much details as possible.

It will help if you supply the original events as they are received from the original remote if you have it.
