Let me describe first my installation that sits on my camper van.
lifepo4 bank of 304Ah cells at 24V
Multiplus II 24/3000/70 connected with the MK3 USB adapter
Smart shunt battery monitor
MPPT's and Orion DC-DC chargers
everything wired up to Venus OS large on RPi
In Venus OS the Smart Shunt is set as main battery monitor in the "System setup" section.
Soooo...Is there a way to get the multiplus to know the SOC mesured by the smart shunt?
I need it to control the ralay of AC out 2 based on SOC for less important load such as A/C unit and water heater, so I can run those loads only when the battery is over 80% SOC for example. I'm doing this with the internal assistant configuration of the multiplus.
I didn't find this specific answer other than old threads that refers to old venus os versions.
I'm aware of the others method to achieve the same results like using relay output on venus os wired to aux input on multiplus or more hardware havy like not using at all ac out 2 and using a contactor wired to a venus os ralay...I don't want to "waste" a ralay on venus os. I need them all for ohters applications.
