addConsumptionOffset API Command Question

[ChutneyMary]

I'm making some modifications to my automation system and wanted to clarify the behaviour of the addConsumptionOffset API.

I can choose to feed just negative values for 'excess' energy into addConsumptionOffset, or I can have a continuous supply of positive to negative values for the household energy state.

I wanted to clarify whether the addConsumptionOffset has a 'PID' (Proportional, Integral, Derivative) type control or is it much simpler.

ie. two scenarios -

1. I'm feeding -16 amps to addConsumptionOffset and a cloud comes over and the household energy state swings to a large consumption value (+8). Will this command a quicker swing to not charging?
2. I'm feeding -16 amps to addConsumptionOffset and a cloud comes over and the household energy state swings to consumption (0 to addConsumptionOffset). Will this command be the same rate as above?

It's very simple. It's treated as another source of consumption/generation data that always returns a fixed amount when checked. TWCManager sums all the consumption/generation available in the system, though most people only have a single source that returns non-zero values.

If you're in a Track Green Energy policy, there is some logic that doesn't immediately stop charging (just drops down to the TWC's minimum amperage) to see if power becomes available again.
