From energy to power?

[dewi-ny-je]

Currently the simulator uses energy to base the battery state changes, which is simple to implement and reliable.

However, some batteries apparently do not operate when the power input/output falls below 50 W (I think it's configurable), otherwise the efficiency would be terrible.

This can be done in the simulator only by changing from an energy-based simulation to a power-based one. Which would require a high resolution power data, for example 1 second in the DSMR entity (it looks like many users are from NL anyway...).

The impact on the CPU load could be very likely visible, 1 second updates are a lot, and I wonder which other system allows for 1 second data (Shelly monitoring maybe?).

Not to mention that power data is more susceptible to biases, while energy readings from a smart meter are always correct.

I'm worried that the change might need to be optional, and two simulation paths might need to be maintained in the code, which is definitely not easy.

Any idea?
