There's an existing topic around this BTW.
Another option is to do this automatically w/o Node-RED if you're familiar with Arduino. There seems to be plenty of tutorials:

I was planning to go this route with our cottage LTE router but a firmware upgrade and an UPS solved the problem before I got to it. Power distribution there is spotty and very often the router did not connect after a power outage. Only power cycling fixed the issue.
