15.0.2

Name: Parameter Migration

Update Procedure

Update Procedure see online documentation

‼️ Afterwards you should force-reload the Web Interface (usually Ctrl-F5 will do it).

Changes

This release only migrates some parameters, see #2023 for details and a list of all parameter changes.
The parameter migration happens automatically on the next startup. No user interaction is required.
A backup of the config is stored on the SD-card as config.bak.

Beside of the parameter change and the bugfix listed below, no changes are contained in this release!

If you want to revert back to v14 or earlier, you will have to revert the migration changes in config.ini manually!

13.0.8

Home Assistant MQTT Discovery Support

Update Procedure

‼️ Make sure to read the instructions below carfully!

1. Backup your configuration (use the System -> Backup/Restore page)!

2. You should update to 12.0.1 before you update to this release. All other migrations are untested.

3. Upload and update the update-*.zip file from this release.

4. Let it restart and check on the System -> Info page that the Firmware as well as the Web UI got updated. If only one got updated, redo the update. If it fails several times, you also can update the Firmware and the Web UI separately.

5. Safe way:

   1. Update first the firmware.bin (extract it from one of the provided zip files) and do the Reboot
   2. Update with the full zip file (update-*.zip, ignore the version warning after the reboot)

6. Please go to Settings -> Configuration and address the changed parameters:

   • DataLogging (storing the values for data graph)
   • Debug (extended by different debug reporting levels)

7. Make sure it starts to do the digitalization (check the Error field on the overview page). If it does not start a round within a minute, restart the device.

If anything breaks you can try to enforce manual update as following:

OTA:
1. Make sure the last run of the update completed the Uploading step.
1. Call http://<IP>/ota?task=update&file=<UPLOAD_FILENAME> to enforce the extraction/flashing.

Initial Setup:
1. Use the initial_esp32_setup.zip ( https://github.com/jomjol/AI-on-the-edge-device/wiki/Installation ) as alternative to have a clean install.

Added

• Implementation of Home Assistant MQTT Discovery

• Improved ROIs configuration: locked ROI geometry, equidistant delta x

• Improved OTA Update mechanism (only working after installation for next update)

• Added data logging in /log/data - One day per file and each measurement is on one line

  • Format: csv - comma separated
  • Content: time, name-of-number, raw-value, return-value, pre-value, change-rate, change-absolute, error-text, cnn-digital, cnn-analog

• Show graph of values direct in the user interface (thanks to @rdmueller)

  • Using new data logging (see above)
  • Possibility to choose different values and switch between different numbers (if present)

12.0.1

Improve user experience

‼️ The release breaks a few things in OTA update ‼️

Make sure to read the instructions below carfully!.

1. Backup your configuration (use the System > Backup/Restore page)!
2. You should update to 11.3.1 before you update to this release. All other migrations are not tested.
   Rolling newer than 11.3.1 can also be used, but no guaranty.
3. Upload and update the firmware.bin file from this release. but do not reboot
4. Upload the html-from-11.3.1.zip in html upload and update the web interface.
5. Now you can reboot.

If anything bricks you can try to

1. Call http://<IP>/ota?task=update&file=firmware.bin resp. http://<IP>/ota?task=update&file=html.zip if the upload successed but the extraction failed.
2. Use the initial_esp32_setup.zip ( https://github.com/jomjol/AI-on-the-edge-device/wiki/Installation ) as alternative.

Added

• Automatic release creation
• Newest firmware of rolling branch now automatically built and provided in Github Actions Output (developers only)
• #1068 New update mechanism:
  • Handling of all files (zip, tfl, tflite, bin) within in one common update interface
  • Using the update.zip from the Release page
  • Status (upload, processing, ...) displayed on Web Interface
  • Automatical detection and suggestion for reboot where needed (Web Interface updates only need a page refresh)
  • ‼️ Best for OTA use Firefox. Chrome works with warnings. Safari stuck in upload.

Changed

• Integrated version info better shown on the Info page and in the log
• Updated menu
• Update used libraries (tflite, esp32-cam, esp-nn, as of 20220924)

Fixed

• #1092 censor passwords in log outputs
• #1029 wrong change of checkDigitConsistency now working like releases before 11.3.1
• Spelling corrections (cristianmitran)

Removed

• Remove the folder /firmware from GitHub repository.
  If you want to get the latest firmware.bin and html.zip files, please download from the automated build action or release page

11.3.1 - Intermediate Digits

‼️ ATTENTION ‼️

1. First update the 'firmware.bin' and ensure that the new version is running.
2. 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!

Changes

• NEW v11.3.1: corrected corrupted asset firmware.bin (v11.3.0).
• 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
