"Nomadic" Power/Energy Monitoring Plugs/Devices

How are you dealing with power/power monitoring devices that you move around? Let’s say a fan with a smart plug that you can move room to room.

I have the Emporia Vue 3 at the breaker panel and other smart plugs for monitoring downstream.

In the Energy Dashboard you can define the upstream device.

Is there a way to autodetect and associate “nomadic” smart plugs with the correct upstream device?
