There is an assistant that can help you. You will need the VE Configure 3 tool, and can download and upload a configuration through VRM.

The assistant you want is the "Charge Current Control".1641312413444.png

This allows you to change the current based on the voltage on one of the aux or temp sensor inputs, 1641312501438.png

I have not used this myself, but understand ion the aux port is not shorted it is less than 1V (aka 0v) and when shorted will be greater than 4v (aka 5v).

Aux input has pull up to +5v, so when open will be at +5, then variable resistance to pull down to zero - if you need analogue, or a switch for on/off.
