> * Device with a low power thermal sensor, cellular connection and a battery that sends a heart beat with the current temperature once every minute or so. Maybe even BLE mesh network of such sensors. Simple patterns like a sudden increase in the are or sensors going offline can indicate something is happening.

I'm not sure what is simple about needing to deploy orders of magnitude more devices to achieve similar levels of coverage...

But a casual passerby spent 5 minutes thinking about a problem and uncovered a solution that the teams of domain experts missed in their years of dedicated work - surely there aren’t any downsides!

Sorry I did not get an authorization from you to discuss things.

No authorization needed! Some humility and self-reflection would be nice but you're free to weigh-in in whichever manner you like.

Because it can be maintenance free, in the middle of nowhere and not rely on source of power and stable connection. https://www.dryad.net/wildfiresensor - here is an example.

I've never done something like it but I'd assume there are lots and lots of gotchas with plans to deploy zero maintenance devices.

It would make sense to me that nonzero, predictable, acceptable maintenance is better than a plan for zero maintenance which, if it fails, would leave you with more devices than you can possibly fix.
