You’re right in that it’s a useful tool for various kinds of abuse, but so is almost every useful home automation/home security sensor.
The most obvious/useful use cases I can see are:
- turn on bedroom lights when the last person gets out of the bed
- turn off whole house lights when the last person gets into bed.
Both should be easy with load cells under the bed legs but rather difficult otherwise.
(Useful assuming a household of two adults in one bed that is).





I did the same except I did the lazy way for idiots: added a cheap USB network adapter to Home Assistant and connected that to a separate network switch. Reolink cameras have been rock solid and haven’t complained about being air gapped from the internet.
