Advice for building a load-cell bed sensor under a non-stabdard bed with no 3d printer

[aaroneisele55 (Aaron Eisele)]

Hello,

I would like to build a load-cell bed occupancy sensor like in this guide but on my bed, each horizontal pair of legs (it has 4) is connected by a wooden bar so I don’t have 4 separate legs but two of these bars.

Could I also just align the load cells like in the guide but on each corner of each bar?

Also, I plan to use this load cell amplifier and 4 of these load cells
Sorry for the German links…
I already have an M5Stack Atom lite ESP32 module, so I went with the M5 module because I am not that good at soldering.

My Questions are:

1. Does the positioning, how I planned it, work for such a bed?
2. How can I mount the cells without a 3D printer?
3. Do these load cells and the amplifier I linked work with ESPHome?

Best regards
Aaron

If you only want bed presence this is a lot simpler:

FSR - the best bed occupancy sensor

Once you have a sensor that can detect you are in bed you will wonder how you automated without it. I use it to turn everything off, turn on my bedside lamp, arm the alarm in perimeter mode, and put my announcements in “do not disturb mode”. When I get up it disarms the alarm and plays my morning announcements. Unfortunately finding a reliable sensor has not been easy. I have tried: A strain gauge glued to a bed slat. It had a reliable detection range and was fast but required re-tuning of …

Where would I mount such an FSR?

That is explained in the topic.
