Sensor (added sensor values) of power and energy looks "not available"

Hi,

i add different sensors in the configuration.yaml (using HA 2023 actual on Raspberry Pi) to set energy-values on state (devices without measurement function). The single values are OK and visible.

now I add a new sensor with the result of 4 sensors (which works as single).
When I try to add the total sensor I failed with “unavaiable”.

here my definitions:

Where is my error, or what have I done wrong?

Powercalc has grouping functionality out of the box. So I suggest to use that as it should make your life much easier.

Hi bramski,
i found the GUI, a little tricky, but it seems to work.

But the problem ist to delete the entities, which are generated “on try and error”. I can’t delete them and i did not find any yaml file with the content.
Did anybody knew a trick or solution?
