The desired output is confusing. (1) Why
LAN..56248? A typo? (there is LAN.56248 in the input). (2) About the line containing 2024-10-02,15:23:17.961821: where did the device… part come from? In the input there is a device… line after 2024-10-02,15:23:17.961821, but I expected it to be assigned to 2024-09-27 11:18:30.389705 that occurs in between. This leads to the next doubt: (3) Why is there no line containing 2024-09-27 in the output? // Please [edit] and clarify. Make sure the example output is exactly what you want to get from the example input you published.
