I've got a couple of spare Wii balance boards lying around, and I want to replace the guts with an ESP home board hooked into its load cells to it into home assistant as a weight sensor.

My goal is to convert them to litterbox stands So I can get metrics on which litter boxes are being used and when. Any recommendations?

I found this few years old GitHub project for a library for the Wiimote and balance board https://github.com/lshachar/WiimoteLib

It's written in C#/.NET though, while .NET is great on Linux these days, last I heard it didn't run so great on ESP boards but is pretty solid on a RPi. That being said, there are 4 weight sensors per board and you might have an easier time with a RPi anyways

Here's a link to an analysis someone out of Japan did of the balance board hardware as well, you'll have to translate the page though it's in Japanese lmao
