Project doesn't work and can't find what's wrong

[XLLegion]

I realise this project is very old, but need it for my own project. I have been fixing quite a few errors with endless more errors, some which I don't know why it isn't working when it should've.

If anyone has an updated version of this, could you please help me out and link your repo?

I've been bugging my brains out the past few days trying to fix it.

It is a shameless drag, but I've just found this project when making the F-Droid merge request for my own (HeartBeat).

As I've seen in other issues, this one checks for the amount of red dropping below the average.
My solution is more convoluted, perhaps for no reason: it takes the rolling average of the past 4 measurements, then it checks for local minima within this series.
