I Try to add the new RFXtrx433XL but i get the error:

is this device not supported yet?

The RFXtrx433XL is set by you to 433.42MHz.
Use RFXmngr to set the RFXtrx433XL back to 433.92MHz and Save Settings.

greate! now i is working. Thanks!

@bweijenberg, @pauli_anttila : Please help me understand this. The RFXtrx433XL operates at both 433.42Mhz and 433.92Mhz, and in the RFXtrx User Guide they write:
The 433.42MHz transmitter in the RFXtrx433E/RFX433XL is used for a reliable control of the Somfy RTS devices over a large distance and through walls.
So it seems they added the 433.42MHz to get better support for Somfy on long distances. However, if I enable that frequency using RFXmngr, I get the error message as shown in this thread (“Unsupported value ‘84’ for TransceiverType”). Does this mean I cannot use this frequency for my Somfy devices? According to the documentation from Somfy their devices uses 433.42MHz, so I guess the precise frequency is needed in case of walls or longer distances.

The RFXtrx can only transmit Somfy RTS commands at 433.42MHz. The RFXtrx switches to 433.42MHz to transmit the Somfy command and will switch back to 433.92Mhz so that sensors and remotes are received at 433.92MHz.
Receive is not implemented for several reasons:
1 Sensors at 433.92MHz are not received anymore if 433.42 is enabled for receive.
2 For security. If you are able to receive a Somfy remote you would be able to control Somfy devices of your neighbors.
3 If you use the same ID as a Somfy remote the remote will become useless because the rolling code is out of sync.
