Also there is https://github.com/jomjol/AI-on-the-edge-device which digitalizes analoge water, gas, power and other meters. It uses the ESP32 camera module and local inference for character recognition. I found this very useful during the gas price hikes to identify effective saving measures. The inference speed is anything but realtime but for this use case fast enough. I took measurements every 5 minutes, the project states: Values smaller than 2 minutes do not make sense, as this is the time for one detection.
