First time poster, long time lurker. I know there have been many threads about this topic, most of them tend to get lost in the weeds and peter out. Please bear with me, I'm an structural engineer and have a fair amount of experience with 12v wiring and circuit design (automotive). I'm learning the differences of 120/240 design as I go, so forgive my ignorance.
INTENT: Modify the remote start fob of a Westinghouse WGen7500 residential generator to signal start and stop based on the presence or lack of grid power.
DESIGN:
I would like to mirror this setup more or less:
WHERE I NEED HELP:
The above one line diagram is a great start but it is lacking the portion of the circuit which would make this a automatically controlled system. I believe it would be as simple as hacking the controller so that upon grid power loss the "Start" button is triggered and released once power production has come on line. Then when grid power is restored the stop button would be triggered and held until generator is shut down fully.
I could use some help and ideas on how to design a circuit that can facilitate the above processes. To me it seems as though it can be accomplished in a low volt circuit utilizing power sensing relays etc.
Ultimately I am not worried about having the remote remain 'mobile', meaning that I can hack it, solder in the circuit and power supply then have it set in some location within the house as the 'control unit'.
Thoughts?

I would like to mirror this setup more or less:
- Auto Transfer Switch (Need suggestions on affordable ATS)
- ATS will switch to Generator power when:
- Grid Power is lost
- Generator power has come on line
- ATS will switch back to grid power when power is restored
- I came across this ATS which fits the bill just not my specs. Not interested in a questionable Chinese component, however the function is exactly what I am looking for.
- ATS will switch to Generator power when:
