SMA Energy Meter not displayed as counter

I have an SMA energy meter installed in the house to count how mich energy is flowing to/from the grid. Nevertheless it doesnt show up on the energy dashboard as a in-out counter. Moreover, in automation, I can just activate the rule based on Watt variation (and not on the energy meter value. E.g. → start the boiler when the house is exporting more than 2400W)
Any sudjestions?
