the gas meter looks similar (QMC5883L Magnetometer Enclosure for Reading Diaphragm Natural Gas Meter by brooksben11 - Thingiverse), but not the same. does anyone know if its the same princible? can a hall effect sensor be used in any capacity too see whether it gives off the same signals?
here are some more photos of the rear for reference, it is very tight, hard to work with lol
