Problem migrating to RFXtrx433XL


Hi, has anyone got the 433XL to work in Vera to control blinds? My old 433E works fine controlling Ematronic blinds using T3 Blinds protocol. I have tried a lot of things to get the XL to work including installing the 1.8 plugin and creating a new RFX device in Vera but while Vera thinks it’s working, the blinds are unresponsive and it also does not auto-create a new blind as the 433E does.
I also tried it with a new Somfy motor awning (which is why I bought the XL) and it does not detect that either.
Both the Ematronic blinds and the Somfy work fine with the XL in RXFmngr.
Thanks for any suggestions.
