I'm about to install a site that is purely DC - no inverter. We will have these victron devices:
MPPT - 250/60
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?
