@lamp personally I thought about some device that would go #pwnagotchi on them and
1. try to autocinnect
2. check internet connectivity
3. scan the natwork
4. log and store the findings for each tested network into a seperate file
5. log all the scanned networks by BSSID & ESSID and don't rescan exact matches unless they weren't successful being connected to in the recent past.

But with the @Raspberry_Pi #PiShortages that's not gonna be feasible...
