Meter description

Easymeter Q3A with WMBus extension ESYSWM20. According to vendor of ESYSWM20 the module sends the data unencrypted.

The data received does not match any telegram description I got from the vendor. Any help or advice would be greatly appreciated.

Here is the debug output I get from wmbusmeters:

Problem found and solved. I have to remove the sticker before plugging in the module...

I will close this ticket in shame...
