## Change log
**General remark:** Besides the file `firmware.bin`, typically the content of `/html` will need to be updated!

##### 11.0.0 - Intermediate Digits

- Implementation of new CNN types to detect intermediate values of digits with rolling numbers

  - By default the old algo (0, 1, ..., 9, "N") is active (due to the limited types of digits trained so far)
  - Activation can be done by selection a tflite file with the new trained model in the 'config.ini'
  - **Details can be found in the [wiki](https://github.com/jomjol/AI-on-the-edge-device/wiki/Neural-Network-Types)** (different types, trained image types, naming convention)

- Updated  neural network files (and adaption to new naming convention)

- Published a tool to download and combine log files - **Thanks to **

  - Files see ['/tools/logfile-tool'](tbd), How-to see [wiki](https://github.com/jomjol/AI-on-the-edge-device/wiki/Gasmeter-Log-Downloader)

- Bug Fix: InfluxDB enabling in grahic configuration

  

## Tools

* Logfile downloader and combiner (Thx to [reserve85](https://github.com/reserve85))
  * Files see ['/tools/logfile-tool'](tbd), How-to see [wiki](https://github.com/jomjol/AI-on-the-edge-device/wiki/Gasmeter-Log-Downloader)
