 # Versions
 
+##### 10.6.2 - Stability Increase (2022-07-24)
+
+- **NEW 10.6.2**: ignore hidden files in model selection (configuration page) 
+
+- **NEW 10.6.1**: Revoke esp32cam & tflite update
+
+- **NEW 10.6.1**: Bug Fix: tflite-filename with ".", HTML spelling error
+
+- IndluxDB: direct injection into InfluxDB - thanks to **[wetneb](https://github.com/wetneb)**
+
+- MQTT: implemented "Retain Flag" and extend with absolute Change (in addition to rate)
+
+- `config.ini`: removal of modelsize (readout from tflite)
+
+- Updated analog neural network file (`ana1000s2.tflite`) & digital neural network file (`dig1400s2q.tflite`)
+
+- TFMicro/Lite: Update (espressif Version 20220716)
+
+- Updated esp32cam (v20220716)
+
+- ESP-IDF: Update to 4.4
+
+- Internal update (CNN algorithm optimizations, reparation for new neural network type)
+
+- Bug Fix: no time with fixed IP, Postprocessing, MQTT
+
+  
+
+##### 10.5.2 - Stability Increase (2022-02-22)
+
+- NEW 10.5.2: Bug Fix: wrong `firmware.bin` (no rate update)
+- NEW 10.5.1: Bug Fix: wrong return value, rate value & PreValue status, HTML: SSID & IP were not displayed 
+- MQTT: changed wifi naming to "wifiRSSI"
+- HTML: check selectable values for consistency
+- Refactoring of check postprocessing consistency (e.g. max rate, negative rate, ...)
+- Bug Fix: corrected error in "Check Consistency Increase"
+
+
+
+##### 10.4.0 - Stability Increase (2022-02-12)
+
+- Graphical configuration: select available neural network files (*.tfl, *.tflite) from drop down menu
+- OTA-update: add option to upload tfl / tflite files to the correct location (`/config/`)
+  - In the future the new files will also be copied to the `firmware` directory of the repository
+- Added Wifi RSSI to MQTT information
+- Updated analog neural network file (`ana-s3-q-20220105.tflite`)
+- Updated digital neural network file (`dig-s1-q-20220102.tflite`)
+- Updated build environment to `Espressif 3.5.0`
+
+
+
+##### 10.3.0 - Stability Increase (2022-01-29)
+
+- Implemented LED flash dimming (`LEDIntensity`). 
+  Remark: as auto illumination in the camera is used, this is rather for energy saving. It will not help reducing reflections
+- Additional camera parameters: saturation, contrast (although not too much impact yet)
+- Some readings will have removable "N"s that can not be removed automatically and are handled with an "error" --> no return value in the field "value" anymore (still reported back via field "raw value")
+- Updated esp32 camera hardware driver
+- Bug fix: MQTT, HTML improvements
+
+**ATTENTION:  The new ESP32 camera hardware driver is much more stable on newer OV2640 versions (no or much less reboots) but seems to be not fully compatible with older versions.**
+
+* If you have problem with stalled systems you can try the following
+  - Update the parameter `ImageQuality` to `12` instead of current value `5` (manually in the `config.ini`)
+
+  - If this is not helping, you might need to update your hardware or stay with version 9.2
+
+##### 10.2.0 - Stability Increase (2022-01-14)
+
+- Due to the updated camera driver, the image looks different and a new setup might be needed
+
+  - Update reference image
+  - Update Alignment marks
+
+- Reduce reboot due to camera problems
+
+- Update esp32-camera to new version (master as of 2022-01-09)
+
+  
+
+##### 10.1.1 - Stability Increase (2022-01-12)
+
+- Bug Fix MQTT problem
+- Issue:
+  - Changing from v9.x to 10.x the MQTT-parameter "Topic" was renamed into "MainTopic" to address multiple number meters. This renaming should have been done automatically in the background within the graphical configuration, but was not working. Instead the parameter "Topic" was deleted and "MainTopic" was set to disabled and "undefined".
+- ToDo
+  - Update the `html.zip`
+  - If old `config.ini` available: copy it to `/config`, open the graphical configuration and save it again.
+  - If old `config.ini` not available: reset the parameter "MainTopic" within the `config.ini` manually
+  - Reboot
+

+
+- MQTT: implemented raw value additionally, removal of regex contrain
+
+- Normalized Parameter ``MaxRateValue``  to "change per minute" 
+

+
+  
+
+##### 9.2.0 - External Illumination (2021-12-02)
+

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

+<h2><strong>Gasmeter Log-Downloader</strong></h2>
+<p>This small tool downloads the logfiles from your ESP32 and stores the last value of the day in an *.csv file.</p>
+<p>To use this tool you need to <strong>activate the debug logfile</strong> in your configuration (Configuration / Debug / Logfile). I go with 30 days of retention in days.</p>
+<p>It downloads only the past logfiles (yesterday and older).</p>
+<p>You can define the max. number of Logfiles to download (beginning from newest [yesterday]).</p>
+<p>I wrote this tool to get a chart of the daily gas consumption to optimize my gas powered heating.</p>
+<p><strong>Variables to define by yourself:</strong></p>
+<ul>
+<li><strong>URL to Logfile-Path on Device:</strong> "http://ESP32-IP-Address/fileserver/log/message/"</li>
+<li><strong>Download Logfiles to:</strong> enter a valid directory, e.g. "D:\Gaszaehler\Auswertung\Log-Downloads\"</li>
+<li><strong>Output CSV-File:</strong> enter a valid directory, e.g. "D:\Gaszaehler\Auswertung\DailyValues.csv"</li>
+<li><strong>Download Logfiles from past # days:</strong> enter the max. number of logfiles you want to download (&lt;= your logfile retention value in your device configuration)</li>
+</ul>
+<p>Feel free to optimize and modify it.</p>
