KNX Energy meter in Energy panel

It seems knx enegy meters can’t be used in the energy panel. I have two meters of the type active_energy_kwh and they don’t show up in the drop-down.

I also tried to customize them by adding state_class with the value total_increasing or measurement but that does not work either.

Does anyone have a solution for this?

EDIT: This is what my entity currently looks like when I open it in the developer tools:

source: 1.1.10
last_knx_update: '2021-08-24 09:37:19.490025+00:00'
unit_of_measurement: kWh
friendly_name: Opgewekt Actief Vermogen
device_class: energy
icon: mdi:home-export-outline
state_class: total_increasing

total_increasing Isn’t released yet - will be included in 2021.9. Then Knx sensor state_class can also be directly configured in yaml.

Beta starts tomorrow. Try it and let us know if you run into problems.
