Use a Pi? SmartSolar MPPT 150/80 & 12V battery & auto-start generator

Hello,

I have a solar system that I'm planning out. It includes the PV arrays, two SmartSolar MPPT 150/80 controllers, a 12V lithium battery, and a Honda EU3000 generator. I want to be able to set it up so that "the system" auto starts the generator when battery SOC is down to 50%, no PV is being produced, and the temperature is above freezing (so the battery can take a charge).

Is this something that can be done with Victron equipment or do I need to use a Rpi? If the answer is to use an Rpi, how will the Pi get the SOC information about the battery?

Many thanks for helping me with my Noob question!

The Standard GX Venus units do this re the AutoStart you have control over these parameters as per picture below

in regards to battery Temp this is normally controlled by the BMS as to weather it allows charge or not. so you may have to install a Temperature controlled relay in the Gen autostart signal control wire. as the below are the only ways to conrol the autostart in the standard venus GX systems
