I got today a response from Kamstrup stating that their repeater's encoding conforms to EN 13757-3 and EN 13757-4. 2013 standards.

Well it seems that code to decode it is available at: https://github.com/fosterbuster/MBusParser/tree/master

Would anyone be willing to add a new driver to wmbusmeters to decode such packets ?

Today wmbusmeters is using lansenrp driver which apparently can not decode READy 5 Repeater's packets.
