Offgrid site - Controlling cooling FAN based on temperature

Hello,

I'm about to install a site that is purely DC - no inverter. We will have these victron devices:

MPPT - 250/60

Venus GX

Smartshunt + temperature sensor

The relay output of the MPPT is already used to control LVD, protecting the batteries from deep discharge.

I'm looking for a way to control a FAN based on the cabinet temperature. It will be very hot in summer, and we do have temperature measurements via smartshunt. However, I can't find an option to control the Venus relay based on this parameter. Is this possible or am I missing something?

You can't do this with the Normal firmware for the Venus but the can be done via NodeRed if you are running the Large firmware. I am doing this exactly but with a Cerbo.
