I see in the example from the manual I need to set the InWRTw = -50% but when I try to inject negative values I get error “RangeError: The value of “value” is out of range. It must be >= 0 and <= 65535. Received -5000”
So how does one do to send negative values?
I have made the following Node-RED test setup but I don’t get it to charge from the power grid or discharge to the power grid.
