Question about using it as a home redundant link
​
I live in rural NY in a cellular dead zone, and I do not see that changing anytime soon.
My parents get their internet through a point-to-point wireless link that I provide from my house, which is about 500 yards away. I was lucky enough to get fiber run to my house years ago because I was teaching remotely at the time, and the local provider used that as the reason to extend service. About 20 other homes eventually signed up once the fiber was brought in.
The issue is power outages.
My parents have an instant-on backup generator, so their house stays powered during an outage. My house, however, does not have a whole-house generator. I travel a lot, and I really do not want to spend $10,000+ on a Generac just to keep my internet equipment running when I am not home. My current battery backup only lasts about 60 minutes.
When my power goes out, my parents lose internet because the point-to-point link from my house goes down, even though their house still has power.
I am looking for the least-hassle emergency backup solution.
Could Starlink be used as a temporary failover internet connection at their house? If so, what equipment would I need besides the Starlink dish to make it automatically fail over when the P2P link from my house goes down?
Has anyone here used Starlink as a backup WAN/failover connection for a rural home network? I am especially interested in real-world setups, router recommendations, and whether this is reliable enough for emergency use during power outages.
I made it clearer, less repetitive, and framed the actual technical question so people on Reddit are more likely to answer.
