Why does everyone think this Amazon essentially handing out your Wi-Fi password? It’s Amazon’s FindMy network but slightly more general purpose where the pings can carry a data payload and are directed to a lambda.

Even if you did manage that somehow, this is still running LoRa for the wireless. IIRC bandwidth is in the single kilobits/s range.
