Your digital ROIs are far to large. Please adjust according to the docs: https://jomjol.github.io/AI-on-the-edge-device-docs/ROI-Configuration/#how-to-setup-the-digit-rois-perfectly |

The Problem
Digit recognition is sometimes way off with very clear picture and no confusion based on the taken image.
I have tried all kind of combinations with the different models and other config settings. The current config (below) delivers the best results at the moment. From time to time the recognition is still off by at least 1qm or even more (up to a couple of hundred qm). As I am transferring the data to Homeassistant this is always combines with unnecessary corrections within the statistics for the watermeter.
Version
v15.3.0 (Commit: 3fbff0a)
Logfile
Expected Behavior
Better recognition result based on very good image quality of the digits.
