how to find deviceID from log entry (peplink max br1)

hi,
i struggle with finding my deviceID - have following log entry

2023-08-16 15:45:02  INFO: [U1e898f5a: taip < 192.168.50.1] 

what is the magic ?

There are do device IDs in what you provided.

ok - interesting ... what is the the device ID i need to register my device in order to get in "online" ... in the payload there is also no deviceID encoded

decoded payload example looks like

RPV60934+4818695+0163625200000002;ID=0000;*72<

and when i send a deviceID configured from the peplink br1 i get

2023-08-16 18:55:16  WARN: Unknown device - 0000 (192.168.50.1)

oooohhaaa - bingo => when i now register the device in traccar with "0000" it works :-)
