In my quest to disable battery charging from the grid, I was playing around with NodeRed and found these 2 options inside the Custom Input and Custom Control.
Max Charge Current output to debug shows 66-68 (amps presumably)
ChargerIsDisabled debugs 0, or false, as expected.
sending an inject to either with a valid input 0-120 or 0/1 is immediately overwritten with the original value shown.
If you intend to disable DVCC charge completely - i have solution to this, which i found playing with assistants.
Setup Current Charge Assistant and check in ‘Disable charge on 0A’ (or similar wording) .
Current Charge assistant is supposed to set Max charge value by AUX1 input (closed/opened) but it has ‘funny’ side effect - setting DC Charge limit to 0A in DVCC disables charging completely !!! So there is no need to hardware input into AUX1 as It works also via Node-Red.
