I have been fiddling with logic to adjust the ESS inverter limit.
The setting in the node allows a value of 0 to any value you like, but there does not seem to be a way to pass a value to disable the limit.
If inverter limits are disabled, the value read back from the node is by default 0 which means no inverting.
Any ideas how this parameter can actually be disabled instead of being left on and configured with a high value?
@Russ as you can see on the GX inverter power limits are disabled:
If you query this value in node red:
It returns 0.
If you set the parameter to 0 then ESS enables limiting and sets it 0W, so no inverting ESS#7
There doesn't seem to be a way to set a disable flag via the same node, you can only set a high enough limit to simulate it being unlimited.
As to the original question, it is a mystery.
I was wondering if the disable flag was actually setting a high value but that wouldn't explain the zero value on read.
There must be some other register. Perhaps settable by mqtt?
To disable it just set it to -1. This works with all values that can be disabled.
Iirc at the time, pulling the value from the node used to show a 0, on current nodes it now reports -1 as expected, which is where the confusion originated.
Now to get state of charge out of the car into node red. :-)
