I've added a device via SNMP, how do I pin it to the dashboard

Hi,
I just installed Home Assistant and added my IP power bar via SNMP.
I can turn the socket on an off under Entities (Info tab) but I can’t figure out a way to add this to the dashboard.

Under Entity Settings I get a message “This entity (‘switch.ipbar1’) does not have a unique ID, therefore its settings cannot be managed from the UI.”

I tried adding a unique ID to configuration.yaml but it looks like SNMP can not use unique_id value - I am not able to do Developer Tools > Restart as long as the configuration file contains unique_id.

I’m a bit lost. Can anyone explain to me what I’m doing wrong please?
