This device always shows decryption error with (securely and moretimes checked) right AES keys, working with other wmbus-solutions.

Debug of WMBusMessagesListener looks the same for this as for normal water_meters, its just not decrypted. Maybe there is a filter before decryption?

The listener is early in the chain, decoding happens later in processing. If you see these it means that message is received properly. Its just applying decryption, which is not done for reserved and other device kinds.

If a Telegram would help you to decide if the assistance make sense, let me know.

As I know the device sends some standard values and some ventor individual as add-on, would be fully fine if not read. I believe it was something like values end of last year, whats send in addition
