+## [12.0.1] 2022-09-29
+
+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

+
+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)

+-   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

+
+## [10.1.1] - (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!
+   
+   
+
+____
+#### #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)

+# Welcome to the AI-on-the-edge-device
+<img src="images/icon/watermeter.svg" width="100px">

-This is an example of Artificial Intelligence (AI) calculations on a very cheap hardware.
+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.

+# 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 CPU usage monitor
+Gives you a rough idea of how the Xtensa cores are utilized.
+
+Works by attaching idle hooks and measuring how often they get called. The core usage is calculated: usage% = idle ticks since last measurement / expected idle ticks if core were idle * 100%. The expected idle tick count was measured by running an empty program.
+
+Limitations:
+Should only be used for user information, not in logic that needs accurate values
+New IDF versions could optimize performance and therefore introduce an error to usage estimation.
+When one core is at 100% the other might report a negative value
