A combination of outdated #Android OS builds, USB debugging being left enabled & vulnerabilities in the bundled apps, malicious actors could gain unauthorized entry into the device and jeopardize user data.
The absolute best part of the #BigEar project is that I can just buy random #BLE sensors and throw them anywhere. Security is such a joke (its just broadcast) but the threat model is "someone driving past might notice that my pool is warm." 🤷 🌡️
(I do mean REALLY anywhere though, within about 4 yards/houses in most directions, using zero equipment outside the main house. Later I'll waterproof one and try it on the fence..)
Y'all shouldn't be buying #oralb toothbrushes or really ANY #bluetooth bathroom scale. Just saying. (And yes, I can probably see your growroom sensor too.)
