Does anybody have an idea how I cool measure the power from a device (car), when I have only the entity “Ampere” and an entity, which shows me if the car is charging or not. My idea is, that I create a helper to calculate the consumption in kWh with this calculation: 16A x 230V x 3 Phases = 11 kWh).
Does anyone have an idea how I can create such an helper or is there another option to do this?
Right, this is the power calculation, not energy. But easy to convert with an integral sensor.
I found the way to create a Sensor-Template, but no idea how to calculate. There must be a calculation like: “name of the entity with Ampere” * 230 * 3
