FactorioIO - Energy Reader (Only one reading)

[Sworn]

I was looking for a mod that output that two top bars that you have in the energy windows (Satisfaction, Production). A guy in the reddit send me here.
I found that you have 3 signals (power consumption, power production and grid satisfaction) but only 1 signal have output.

Actually power consumption and power production have readings, but they read the same value, so no much use in there.
The grid satisfaction never reads anything.

I found no information in the mod portal if I actually need to do something for that to work or if it's a bug...

Would be awesome to be able to read the 2 top bars (Satisfaction, Production) of the energy window.
My guess was that the Satisfaction = power consumption and Production = power production but it is only a guess.
More inormation would be nice to have.

I was trying to fix it, but I have no idea how to change it.
They output the same value and will always output the same value as the consumption and production are always the same in the game guy energy.
They should output the % value of each bar like the accumulator does.
