Signal? Isn’t that the app for drugs? /s

Every time I see that URL, I wince

I use openscale and a Beuer BF700 (I think that’s the model #, it’s a model listed in the github wiki) and it works great, although I had to do the initial setup on their proprietary app to get the profiles to work right, and the scale had to be imported/was a bit hard to find. The wiki includes instructions for modifying a scale to add an arduino and the necessary bits to DIY one if you’re at all technically inclined.

I recommend it, but YMMV if you try to use a newer scale. If I ever have more time I would like to try to extend the drivers to support more scales, because openscale is very good software.
