Slightly old post, but hopefully still helpful to someone:
I managed to read out my analog water meter using the following ESP32 image: https://github.com/jomjol/AI-on-the-edge-device
It uses an ESP32-CAM module that actively reads your meter, using machine vision. The data is then published via MQTT. There are even some stl files for cases/mounts for common energy meters.
Once setup properly (with a 3D printed case from the provided stl files), I found it to work quite well. I have a pretty clean standard German water meter though.
