A search on the MAC addresses (00:30:59:03:13:58, 00:c0:3a:8d:11:05) at the Wireshark oui-lookup:

00:30:59 Kontron Europe GmbH
00:C0:3A duagon Germany GmbH

https://www.kontron.com/en
https://www.duagon.com/

They are both IOT vendors.
Duagon also makes gateways so the destination could be a different device on the other side of it.
