I have a Hypervolt EV charger and I’ve installed the HACS Hypervolt intergration for it.
So, I now have two sensors: a tariff myTariff in p/kWh and a session energy hypervolt_session_energy in Wh.
What is the workflow to build a cost per session sensor? I’ve hunted around the Helper/Template/Sensor area but up to now nothig is working for me?
