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?

Aliexpress has load cells that go up to the hundreds of KGS. One of those, an esp32/pico and some wiring and you should be good to go?

This. I bought a few myself, but didn't have time to put them together with ESP32/program them with ESPHome

Couldn't find the exact one I ordered a few months ago, but this type of pressure sensor aliexpress link is apparently a common bed occupancy sensor type used when building medical beds for hospitals and care homes so staff can be alerted when a patient gets out of bed. I'm not sure the specific model I linked is quite right specs-wise, but the idea is that it goes on a slat or other surface between the matress and the frame that doesn't necessarily get the full weight of the occupant, but still gets enough to measure on the sensor.
