  1 2 10.0 Python

  Analog Mater Reader using OpenCV/Python

If you need the precise values shown on the meter then you'll need to rig up a camera. You'll also need to space it far enough away that it can focus on the meter + have sufficient illumination. Take stills and then feed it into OpenCV. Something like https://github.com/mirogta/dial-meter-reader-opencv-py

  Easy to use device for connecting "old" measuring units (water, power, gas, ...) to the digital world

https://github.com/jomjol/AI-on-the-edge-device is a ESP32-CAM based one which does both dials and numeric readouts. It'll be much cheaper than a Pi based system.
