Waterlink smart meters update
I get this kind of picture which is a bit shitty because of the low-contrast display and non ideal placement of the flash, but is actually good enough to OCR. The AI-on-the-edge project didn't work well for me because it takes ages to process one photo and I want better precision than that, so I rigged up a script that uses imagemagick to rotate, crop and threshold the image to something like that and then ssocr (github) does the job of actually recognizing the numbers.

Where to start on a specific project, new to coding.
In my research I extensively use a software suite that was developed in the early '90 in the Information Science Research Institute in Las Vegas called ISRI tools for OCR evaluation. This tools were ported for modern systems and are maintained at: https://github.com/eddieantonio/ocreval. The tools are used via Linux Terminal and they give large amounts of data on different aspects of text recognition process, and the output is in plain text format.
What are some alternatives?
AI-on-the-edge-device - Easy to use device for connecting "old" measuring units (water, power, gas, ...) to the digital world
ccextractor - CCExtractor - Official version maintained by the core team
iohook - Node.js global keyboard and mouse listener.
