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?

Use car occupancy sensors and an esp board. That's what I did. I stuck them to corregated cardboard and put one under each side. Aim for the butt area as that seems to apply the most pressure. I would order 4. 2 for each side because you can put them in parallel to divide the resistance and make them easier to trigger.

Buy them on AliExpress or eBay.
