Somfy (ASA) Awning controlled by Vera Plus through RFXtrx433E

I have a Transceiver RFXtrx433E registered in my Vera Plus as the way to incorporate in the platform the devices that work with 433,92MHz remote controls.
I have been able to include an awning which is Somfy protocol and it works well with the Transceiver through the Manager Program directly connected to the laptop.
The problem appears when I try to include it in my Vera PLus. Everything goes alright until I have to select the category, I use RFY, the new device is registered but nothing happens. I use the same data that allowed me to register the awning on the Transceiver (Id decimal and Unit Code) and the only difference is that the Vera Plus doesn’t offer “ASA” as a subcategory of RFX category as the Transceiver has in the Manager Program.
Any posible solution?
