Change log

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

---

11.3.1 - Intermediate Digits (2022-09-17)

• ATTENTION:

  • first update the 'firmware.bin' and ensure that the new version is running

  • Only afterwards update the 'html.zip'

  • Otherwise the downwards compatibility of the new counter clockwise feature is not given and you end in a reboot loop, that needs manual flashing!

• NEW v11.3.1: corrected corrupted asset firmware.bin

• Increased precision (more than 6-7 digits)

• Implements Counter Clockwise Analog Pointers

• Improved post processing algorithm

• Debugging: intensive use of testcases

• MQTT: improved handling, extended logging, automated reconnect

• HTML: Backup Option for Configuration

• HTML: Improved Reboot

• HTML: Update WebUI (Reboot, Infos, CPU Temp, RSSI)

• This version is largely also based on the work of caco3, adellafave, haverland, stefanbode, PLCHome

11.2.0 - Intermediate Digits (2022-08-28)

• Updated Tensorflow / TFlite to newest tflite (version as of 2022-07-27)

• Updated analog neural network file (ana-cont_11.3.0_s2.tflite - default, ana-class100_0120_s1_q.tflite)

• Updated digital neural network file (dig-cont_0570_s3.tflite - default, dig-class100_0120_s2_q.tflite)

• Added automated filtering of tflite-file in the graphical configuration (thanks to @caco3)

• Updated consistency algorithm & test cases

• HTML: added favicon and system name, Improved reboot dialog (thanks to @caco3)

11.1.1 - Intermediate Digits (2022-08-22)

• New and improved consistency check (especially with analog and digital counters mixed)
• Bug Fix: digital counter algorithm

11.0.1 - Intermediate Digits (2022-08-18)

• NEW v11.0.1: Bug Fix InfluxDB configuration (only update of html.zip necessary)

• 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 (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', How-to see wiki

• Bug Fix: InfluxDB enabling in grahic configuration

Tools

• Logfile downloader and combiner (Thx to reserve85)
  • Files see '/tools/logfile-tool', How-to see wiki

Additional Ideas

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