Control 2 ATS's independently from one generator

[h2ofun]

I saw a thread on this, but it was closed.
I have a need to have either of my ATS's that can lose power to turn on my generator. Total, the master has to lose power, then it forces both
ATS's which control my two 200 amp sub-panels to run off the generator.

For most folks, this is fine. But in my setup, I have a 400 amp main, which drive two 200 amp breakers, These both go to Tesla Gateways, which each have tesla powerwalls attached. (THis is because Tesla does not make a single 400 amp gateway)

So, I have the want that if I lose grid power, and then I lose one of my bank of powerwalls batteries, I want to ONLY have this ATS's trigger the generator to run and power it. I want the other ATS to continue to run off the charged tesla powerwall batteries.
So, as more batteries get used, in larger homes, my setup might become more common.

So this is such a great challenge
