+
+Name: Improve **u**ser e**x**perience 
+
+:bangbang: The release breaks a few things in ota update :bangbang:
+
+**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 breaks 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.
+1\. Use the initial_esp32_setup.zip ( <https://github.com/jomjol/AI-on-the-edge-device/wiki/Installation> ) as alternative.
+
+### Added
+

+    -   Using the `update.zip` from the [Release page](https://github.com/jomjol/AI-on-the-edge-device/releases)
+    -   Status (`upload`, `processing`, ...) displayed on Web Interface
+    -   Automatical detection and suggestion for reboot where needed (Web Interface uupdates only need a page refresh)
+    -   :bangbang: 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)

+## [10.5.2](https://github.com/jomjol/AI-on-the-edge-device/releases/tag/v10.5.2), 2022-02-22
+
+Stability Increase
+
+### Changed
+
+-   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

+
+## [10.3.0] - (2022-01-29)
+
+Stability Increase
+
+### Changed
+
+-   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] - (2022-01-14)
+
+Stability Increase
+
+### Changed
+
+-   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] - (2022-01-12)
+
+ Stability Increase
+
+### Changed
+
+-   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
+

+## Feature Requests
+
+**There are a lot of ideas for further improvements, but only limited capacity on side of the developer.** Therefore I have created this page as a collection of ideas. 
+
+1. Who ever has a new idea can put it here, so it that it is not forgotten. 
+
+2. Who ever has time, capacity and passion to support, can take any of the ideas and implement them. 
+   I will support and help where ever I can!
+   
+   
+
+____
+#### #36 Run demo without camera
+Demo mode requires a working camera (if not, one receives a 'Cam bad' error). Would be nice to demo or play around on other ESP32 boards (or on ESP32-CAM boards when you broke the camera cable...).
+
+#### #35 Use the same model, but provide the image from a Smartphone Camera
+as reading the Electricity or Water meter every few minutues only delivers apparent accuracy (DE: "Scheingenauigkeit") you could just as well take a picture with your Smartphone evey so often (e.g. once a week when you are in the Basement anyway), then with some "semi clever" tricks pass this image to the model developed here, and the values then on to who ever needs them e.g. via MQTT.
+IMO: It is not needed to have that many readings (datapoints) as our behaviour (Use of electricity or water) doesn't vary that much, say, over a weeks time. The interpolation between weekly readings will give sufficient information on the power and/or water usage. 
+
+
+#### #34 implement state and Roi for water leak detection
+for example see Roi on the next picture..
+![grafik](https://user-images.githubusercontent.com/38385805/207858812-2a6ba41d-1a8c-4fa1-9b6a-53cdd113c106.png)
+in case of position change between the measurments set this state to true, if there is no change set it back to false.
+In a defined time window this movement can lead into an alarm state / water leak..
+haveing this state in the mqtt broker can trigger functions like closing the ater pipe walve and so on...
+
+
+
+#### #33 Implement MATTER protocoll
+
+* see [#1404](https://github.com/jomjol/AI-on-the-edge-device/issues/1404)
+
+#### #32 Add feature to correct misinterpreted value
+
+* If a value is misinterpreted, the user can manually correct the value.
+* The misinterpreted ROIs would be saved in a "training data" -folder on the SD-card
+* Stretch goal: make sending of saved training data as easy as pushing a button =)
+
+#### #31 Implement InfluxDB v2.x interface
+
+* Currently only InfluxDB v1.x is supportet, extend to v2.x
+* Remark: interface has changed
+* see [#1160](https://github.com/jomjol/AI-on-the-edge-device/issues/1160)
+
+#### #30 Support meter clock over
+
+* In case of meter clocking over, that is, reaching its max. value and starting over from 0,
+  accept the new value and calculate correctly the difference.
+  (see line 739 onwards in ClassFlowPostProcessing.cpp)
+
+#### ~~#29 Add favicon and use the hostname for the website~~- implemented v11.3.1
+
+~~* https://github.com/jomjol/AI-on-the-edge-device/issues/927~~
+
+#### #28 Improved error handling for ROIs
+
+* In case a ROI is out of the image, there is no error message, but a non sense image is used
+* Implement a error message for wrong configuratioin of ROI
+
+#### #27 Use Homie Spec for Mqtt binding
+
+* Use the standardized Home Protocol for the Mqtt binding 
+* https://homieiot.github.io/
+
+#### #26 Changes behaviour for "N" replacement
+
+* in case the higher digits has already increased by minium 1 - don't set the "N" to the last value, but to "0"
+* https://github.com/jomjol/AI-on-the-edge-device/issues/792
+
+
+#### #25 Trigger Measurement via MQTT
+
+* https://github.com/jomjol/AI-on-the-edge-device/issues/727
+
+
+#### #24 Show Mqtt state directly in Webserver
+
+* Show MQTT log in Web page. E.g. connection established or failed to connect...
+
+  
+
+
+#### #23 CPU Temp and Mqtt values
+
+* Show the CPU Temp directly in Webpage. Also add the value to MQTT sending
+
+  
+
+#### ~~#22 Direct hint to the different neural network files in the other repositories~~- implemented >v11.3.1
+
+~~* https://github.com/jomjol/AI-on-the-edge-device/issues/644~~
+
+  
+
+#### #21 Extended "CheckDigitalConsistency" Logik
+
+* https://github.com/jomjol/AI-on-the-edge-device/issues/590
+
+  
+
+#### #20 Deep sleep and push mode
+
+* Let the device be normally in deep sleep state, and wake it up periodically to collect data and push it via MQTT or HTTP post.
+* Support ESP-NOW to reduce the overhead of connecting to wifi and mqtt 
+* the above should enable battery powered applications
+
+* An other way to set deep sleep would be to enable it in a specific period (at night).
+  
+
+#### #19 Extended log informations

+Artificial intelligence based systems have been established in our every days live. Just think of speech or image recognition. Most of the systems relay on either powerful processors or a direct connection to the cloud for doing the calculations up there. With the increasing power of modern processors the AI systems are coming closer to the end user - which is usually called **edge computing**.
+Here this edge computing is brought into a practical oriented example, where a AI network is implemented on a ESP32 device so: **AI on the edge**.
 
-### Details on **function**, **installation** and **configuration** can be found on the **[Wiki Page](https://github.com/jomjol/AI-on-the-edge-device/wiki)**
+This projects allows you to digitalize your **analoge** water, gas, power and other meters using cheap and easily available hardware.
 
-A 3d-printable housing can be found here: https://www.thingiverse.com/thing:4571627
+All you need is an [ESP32 board with a supported camera](https://jomjol.github.io/AI-on-the-edge-device-docs/Hardware-Compatibility/) and a bit of a practical hand.
 
+<img src="images/esp32-cam.png" width="200px">
+
+## Key features
+- Tensorflow Lite (TFlite) integration - including easy to use wrapper
+- Inline Image processing (feature detection, alignment, ROI extraction)
+- **Small** and **cheap** device (3x4.5x2 cm³, < 10 EUR)
+- camera and illumination integrated
+- Web surface to administrate and control
+- OTA-Interface to update directly through the web interface
+- Full integration into Homeassistant
+- Support for Influx DB 1
+- MQTT
+- REST API
+
+## Workflow
+The device takes a photo of your meter at a defined interval. It then extracts the Regions of Interest (ROI's) out of it and runs them through an artificial inteligence. As a result, you get the digitalized value of your meter.
+
+There are several options what to do with that value. Either send it to a MQTT broker, write it to an InfluxDb or simply provide it throug a REST API.

+## Setup
+There is a growing [documentation](https://jomjol.github.io/AI-on-the-edge-device-docs/) which provides you with a lot of information.
+Head there to get a start, set it up and configure it.
+
+There are also a articles in the German Heise magazine "make:" about the setup and the technical background (behind a paywall) : [DIY - Setup](https://www.heise.de/select/make/2021/2/2103513300897420296)
+
+For further background information, head to [Neural Networks](https://www.heise.de/select/make/2021/6/2126410443385102621), [Training Neural Networks](https://www.heise.de/select/make/2022/1/2134114065999161585) and [Programming on the ESP32](https://www.heise.de/select/make/2022/2/2204010051597422030) 
+
+### Download
+The latest available version is available on the [Releases page](https://github.com/jomjol/AI-on-the-edge-device/releases).
+
+### Flashing of the ESP32
+Initially you will have to flash the ESP32 through an USB connection. Later an update is possible directly over the Air (OTA).
+
+There are different ways to flash your ESP32:
+- [Web Installer and Console](https://jomjol.github.io/AI-on-the-edge-device/index.html) (Webbrowser based tool to flash the ESP32 and extract the Log over USB)
+- Flash Tool from Espressif
+- ESPtool (Command Line Tool)
+
+See the [Docu](https://jomjol.github.io/AI-on-the-edge-device-docs/Installation/) for more information.
+
+### Flashing the SD-Card
+The SD-Card must be flashed separately, see the [Docu](https://jomjol.github.io/AI-on-the-edge-device-docs/Installation/) for details.

+# Build
+
+## Preparations
+```
+git clone https://github.com/jomjol/AI-on-the-edge-device.git
+cd AI-on-the-edge-device
+git checkout rolling
+git submodule update --init
+```
+
+## Build and Flash within terminal
+See further down to build it within an IDE.
+### Compile
+```
+cd code
+platformio run --environment esp32cam
+```
+
+### Upload
+```
+pio run --target upload --upload-port /dev/ttyUSB0
+```
+
+Alternatively you also can set the UART device in `platformio.ini`, eg. `upload_port = /dev/ttyUSB0`
+
+### Monitor UART Log
+```
+pio device monitor -p /dev/ttyUSB0
+```
+
+## Build and Flash with Visual Code IDE
+
+- Download and install VS Code
+  - https://code.visualstudio.com/Download
+- Install the VS Code platform io plugin
+  - <img src="https://raw.githubusercontent.com/jomjol/ai-on-the-edge-device/master/images/platformio_plugin.jpg" width="200" align="middle">
+  - Check for error messages, maybe you need to manually add some python libraries
+    - e.g. in my Ubuntu a python3-env was missing: `sudo apt-get install python3-venv`
+- git clone this project
+  - in Linux: 
+
+    ```
+    git clone https://github.com/jomjol/AI-on-the-edge-device.git
+    cd AI-on-the-edge-device
+    git checkout rolling
+    git submodule update --init
+    ```
+
+- in VS code, open the `AI-on-the-edge-device/code` 
+	- from terminal: `cd AI-on-the-edge-device/code && code .`
+- open a pio terminal (click on the terminal sign in the bottom menu bar)
+- make sure you are in the `code` directory
+- To build, type  `platformio run --environment esp32cam`
+  - or use the graphical interface:
+    <img src="https://raw.githubusercontent.com/jomjol/ai-on-the-edge-device/master/images/platformio_build.jpg" width="200" align="middle">
+  - the build artifacts are stored in  `code/.pio/build/esp32cam/`
+- Connect the device and type `pio device monitor`. There you will see your device and can copy the name to the next instruction
+- Add `upload_port = you_device_port` to the `platformio.ini` file
+- make sure an sd card with the contents of the `sd_card` folder is inserted and you have changed the wifi details
+- `pio run --target erase` to erase the flash
+- `pio run --target upload` this will upload the `bootloader.bin, partitions.bin,firmware.bin` from the `code/.pio/build/esp32cam/` folder. 
+- `pio device monitor` to observe the logs via uart

-# ESP32 Camera Driver
-
-## General Information
-
-This repository hosts ESP32 compatible driver for OV2640, OV3660, OV5640, OV7670 and OV7725 image sensors. Additionally it provides a few tools, which allow converting the captured frame data to the more common BMP and JPEG formats.
-
-## Important to Remember
-
-- Except when using CIF or lower resolution with JPEG, the driver requires PSRAM to be installed and activated.
-- Using YUV or RGB puts a lot of strain on the chip because writing to PSRAM is not particularly fast. The result is that image data might be missing. This is particularly true if WiFi is enabled. If you need RGB data, it is recommended that JPEG is captured and then turned into RGB using `fmt2rgb888` or `fmt2bmp`/`frame2bmp`.
-- When 1 frame buffer is used, the driver will wait for the current frame to finish (VSYNC) and start I2S DMA. After the frame is acquired, I2S will be stopped and the frame buffer returned to the application. This approach gives more control over the system, but results in longer time to get the frame.
-- When 2 or more frame bufers are used, I2S is running in continuous mode and each frame is pushed to a queue that the application can access. This approach puts more strain on the CPU/Memory, but allows for double the frame rate. Please use only with JPEG.
-
-## Installation Instructions
-
-
-### Using esp-idf
-
-- Clone or download and extract the repository to the components folder of your ESP-IDF project
-- Enable PSRAM in `menuconfig`
-- Include `esp_camera.h` in your code
-
-### Using PlatformIO
-
-The easy way -- on the `env` section of `platformio.ini`, add the following:
-
-```ini
-[env]
-lib_deps =
-  esp32-camera
-```
-
-Now the `esp_camera.h` is available to be included:
-
-```c
-#include "esp_camera.h"
-```
-
-Enable PSRAM on `menuconfig` or type it direclty on `sdkconfig`. Check the [official doc](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/kconfig.html#config-esp32-spiram-support) for more info.
-
-```
-CONFIG_ESP32_SPIRAM_SUPPORT=y
-```
-
-***Arduino*** The easy-way (content above) only seems to work if you're using `framework=arduino` which seems to take a bunch of the guesswork out (thanks Arduino!) but also suck up a lot more memory and flash, almost crippling the performance.  If you plan to use the `framework=espidf` then read the sections below carefully!!
-
-## Platform.io lib/submodule (for framework=espidf)
-
-It's probably easier to just skip the platform.io library registry version and link the git repo as a submodule. (i.e. using code outside the platform.io library management). In this example we will install this as a submodule inside the platform.io $project/lib folder: 
-```
-cd $project\lib
-git submodule add -b master https://github.com/espressif/esp32-camera.git
-```
-
-Then in `platformio.ini` file
-```
-build_flags =
-   -I../lib/esp32-camera
-```
-After that `#include "esp_camera.h"` statement will be available. Now the module is included, and you're hopefully back to the same place as the easy-Arduino way. 
-
-**Warning about platform.io/espidf and fresh (not initialized) git repos**
-There is a sharp-edge on you'll discover in the platform.io build process (in espidf v3.3 & 4.0.1) where a project which has only had `git init`  but nothing committed will crash platform.io build process with highly non-useful output.  The cause is due to lack of a version (making you think you did something wrong, when you didn't at all) - the output is horribly non-descript.  Solution: the devs want you to create a file called version.txt with a number in it, or simply commit any file to the projects git repo and use git. This happens because platform.io build process tries to be too clever and determine the build version number from the git repo - it's a sharp edge you'll only encounter if you're experimenting on a new project with no commits .. like wtf is my camera not working let's try a 'clean project'?!  </rant> 
-
-## Platform.io Kconfig 
-Kconfig is used by the platform.io menuconfig (accessed by running: `pio run -t menuconfig`) to interactively manage the various #ifdef statements throughout the espidf and supporting libraries (i.e. this repo: esp32-camera and arduino-esp32.git).  The menuconfig process generates the `sdkconfig` file which is ultimately used behind the scenes by espidf compile+build process. 
-
-**Make sure to append or symlink** [this `Kconfig`](./Kconfig) content into the `Kconfig` of your project. 
-
-You symlink (or copy) the included Kconfig into your platform.io projects src directory.  The file should be named `Kconfig.projbuild` in your projects src\ directory or you could also add the library path to a CMakefile.txt and hope the `Kconfig` (or `Kconfig.projbuild`) gets discovered by the menuconfig process, though this unpredictable for me. 
-
-The unpredictable wonky behavior in platform.io build process around Kconfig naming (Kconfig vs. Kconfig.projbuild) occurs between espidf versions 3.3 and 4.0 - but if you don't see "Camera configuration" in your `pio run -t menuconfig` then there is no point trying to test camera code (it may compile, but it probably won't work!) and it seems the platform.io devs (when they built their wrapper around the espidf menuconfig) didn't implement it properly.  You've probably already figured out you can't use the espidf build tools since the files are in totally different locations and also different versions with sometimes different syntax.   This is one of those times you might consider changing the `platformio.ini` from `platform=espressif32` to `platform=https://github.com/platformio/platform-espressif32.git#develop` to get a more recent version of the espidf 4.0 tools. 
-
-However with a bit of patience and experimenting you'll figure the Kconfig out. Once Kconfig (or Kconfig.projbuild) is working then you will be able to choose the configurations according to your setup or the camera libraries will be compiled.  Although you might also need to delete your .pio/build directory before the options appear .. again, the `pio run -t menuconfig` doens't always notice the new Kconfig files! 
-
-If you miss-skip-ignore this critical step the camera module will compile but camera logic inside the library will be 'empty' because the Kconfig sets the proper #ifdef statements during the build process to initialize the selected cameras.  It's very not optional!

-// Public domain, Rich Geldreich <richgel99@gmail.com>
-// v1.01, Dec. 18, 2010 - Initial release
-// v1.02, Apr. 6, 2011 - Removed 2x2 ordered dither in H2V1 chroma subsampling method load_block_16_8_8(). (The rounding factor was 2, when it should have been 1. Either way, it wasn't helping.)
-// v1.03, Apr. 16, 2011 - Added support for optimized Huffman code tables, optimized dynamic memory allocation down to only 1 alloc.
-//                        Also from Alex Evans: Added RGBA support, linear memory allocator (no longer needed in v1.03).
-// v1.04, May. 19, 2012: Forgot to set m_pFile ptr to NULL in cfile_stream::close(). Thanks to Owen Kaluza for reporting this bug.
-//                       Code tweaks to fix VS2008 static code analysis warnings (all looked harmless).
-//                       Code review revealed method load_block_16_8_8() (used for the non-default H2V1 sampling mode to downsample chroma) somehow didn't get the rounding factor fix from v1.02.
