G2 misuratori water meter reading (alternatives to AI on the edge?)

Hi there Home Assistant community!

I want to track my water usage, but I am having trouble with the meter I have. I would like to hear if you people have any ideas how to get around the limitations.

My water company has installed a G2 misuratori water meter (model PFM-R100H T50) in my home and I won’t be eligible for a new meter until 2027. The technical specs can be found here: https://www.g2misuratori.it/themes/user/site/files/2019-10_bfm-bcm-pfm-R200-R100-en.pdf

To the best of my knowledge, this meter does not have a magnet or a reed. I am currently using AI on the edge to read it, however I have been unable to make it work reliably (it keeps misreading the water use by millions of liters). Below is a image of the meter from AI on the Edge:

Most of the ready solutions (like HomeWizard) are not compatible with my meter (to my knowledge), much to my chagrin.

I would like to hear if anyone has any alternatives I could have for measuring (even roughly) the water use (something I can attach to the pipes perhaps?). I don’t need it to be exact, but it should be at least somewhat reliable

Thanks!

Strange. I use it for my electricity meter, and it’s indeed unreliable, but the pictures I’m able to take are of far less quality than yours

I’ve managed to improve the reference image with no glare over the analog meters and only a -0.5 degree fine tune required.

I will report if the AI on the edge device gets funky again.
