Allow battery without energy input sensor

[snooopy3652]

Hello,
I'm using one charger to charge different batteries at the same time.
Now I had to create a "Fake" sensor for my second battery, without this I wasn't able to intergrate it into the Energy-Board.
Because the 2 batteries are using different inverters for energy output, I couldn't integrate them as one battery.

I could combine them into 1 helper sensor, or use a fake energy input sensor for one of the battery.
Since in the statistic power input is not divided into different numbers anyway, I did choose the "dummy sensor".

It does work but I'm always seeing the "yellow !" in the Dashboard configuration.
Is it possible to just remove the need of an energy input for any battery, when using more then one?

Thanks :) and keep on doing the good work.
