Hey @Robbie we are working in order to improve the UI and UX, but if you have more interfaces they will be shown on the dashboard.
We have an example that introduces the mac address as a tag. You can try this code → basicstation/start.sh at master · balenalabs/basicstation · GitHub where there is an example to introduce the mac address from eth0 as a tag. You will need to change the TTN_EUI to publish just the mac address and not the EUI
