Home Assistant Energy Component Empty

I have multiple Esphome piwer measurement sensors, that feed utility meter sensors.

Once such displayed below

I can not see any information “missing” but the drop down in the energy component is empty.

You still need

device_class: energy

As far as im aware you cannot add that to utility meter.
This is my source sensor

This is also not available in the energy panel
Sensor is an ESPHOME integration
