Coming next

Automated update of the neural network file (tflite) to make the learing of additional pictures much easier and automated (GitHub action)
New "hyprid" neural network for digital numbers --> allowing the detection of intermediate states ("ring between two numbers") as a subdigit

Change log

Known Issues

slow response of web server during picture analysis
spontaneous reboots (mostly due to html access during image processing) - self recovery implemented

General remark: Beside the firmware.bin, typically also the content of /html needs to be updated!

10.0.2 - Stability Increase (2022-01-01)

NEW v10.0.2: Corrected JSON error
Updated compiler toolchain to ESP-IDF 4.3
Removal of memory leak
Improved error handling during startup (check PSRAM and camera with remark in logfile)
MQTT: implemented raw value additionally, removal of regex contrain
Normalized Parameter MaxRateValue to "change per minute"
HTML: improved input handling
Corrected error handling: in case of error the old value, rate, timestamp are not transmitted any more

9.2.0 - External Illumination (2021-12-02)

Direct JSON access: http://IP-ADRESS/json
Error message in log file in case camera error during startup
Upgrade analog CNN to v9.1.0
Upgrade digital CNN to v13.3.0 (added new images)
html: support of different ports

9.1.1 - External Illumination (2021-11-16)

NEW 9.1.1 bug fix: LED implemenetation
External LEDs: change control mode (resolve bug with more than 2 LEDs)
Additional info into log file
Bug fix: decimal shift, html, log file

9.0.0 - External Illumination (2021-10-23)

Implementation of external illumination to adjust positioning, brightness and color of the illumination now individually
- Technical details can be found in the wiki: https://github.com/jomjol/AI-on-the-edge-device/wiki/External-LED
New housing published for external LEDs and small clearing: https://www.thingiverse.com/thing:5028229

Additional ideas

There are some ideas and feature request, which are not followed currently - mainly due to capacity reasons on side of the developer. They are collected here: FeatureRequest.md
