When a tag successfully checks-in on a sensor, the sensor sends a special message with the tag ID to the cloud. To recognize these registration messages you need to find messages with the first byte of payload equal to 0A(first byte shows from which LoRaWAN port the message was received, so if you want to see this message in your LoRaWAN network it is port 10 and 5 bytes of data, the last 4 bytes are tag ID) as on the picture below. Bytes 3..6 contain big-endian 32-bit tag ID, so here the ID is AB00012C.
