I have the same Fronius options and have everything working fine with the set up posted here:
From the Energy Configuration page I set the required inputs to the following sensors:
[Electricity grid] (requires Smart Meter):
Grid consumption: sensor.energy_real_consumed_fronius_meter_...
Return to grid: sensor.energy_real_ac_minus_fronius_meter_... (or use ..real-produced.. instead)
[Solar panels] (from inverter)
Solar production: sensor.energy_total_fronius_inverter_...
These sensors all provide cumulative totals of energy flows (as required, which the new UI cards process to generate their required output values).
I’m using the ‘standard’ Fronius platform sensor.
It’s a very welcome addition for tracking energy use:
