Bed Occupancy Sensor? (lemmy.ml)

Anyone try to build a bed occupancy sensor integrated with Home Assistant? I've looked into load sensors but all of them seem to have pretty small weight limits (low enough to where I don't think it would even support the empty bed).

What devices/sensors have you used for this? And what does your setup look like?

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).
