Add device to dashboar energy

Hello. Buy a zigbee device that measures electrical consumption.
Create a mqtt entity in which I can see the consumption that I have. But I don’t know how to add that device to the dashboard. I had a device that measured a sector and now it measures the entire consumption of the house. I can’t find a place in the dashboard to add the device and I don’t remember how to add the other one. Thank you so much
