-# How to compile AirGradient firmware on Arduino IDE
-
-## Prequisite
-
-Arduino IDE version 2.x ([download](https://www.arduino.cc/en/software))
-
-> For AirGradient model ONE and Open Air, the codebase **WILL NOT** work on the latest major version of arduino-esp32 which is *3.x* . This related to when installing "esp32 by Espressif Systems" in board manager. Instead use version **2.0.17**, please follow the first step carefully.
-
-## Steps for ESP32C3 based board (ONE and Open Air Model)
-
-1. Install "esp32 by Espressif Systems" in board manager with version **2.0.17** (Tools ➝ Board ➝ Boards Manager ➝ search for `"espressif"`)
-
-![board manager](images/esp32-board.png)
-
-2. Install AirGradient library
-
-#### Version < 3.2.0
-
-Using library manager install the latest version (Tools ➝ Manage Libraries... ➝ search for `"airgradient"`) 
-
-![Aigradient Library](images/ag-lib.png)
-
-#### Version >= 3.3.0
-
- From your terminal, go to Arduino libraries folder (windows and mac: `Documents/Arduino/libraries` or linux: `~/Arduino/Libraries`).
- With **git** cli, execute this command `git clone --recursive https://github.com/airgradienthq/arduino.git AirGradient_Air_Quality_Sensor` 
- Restart Arduino IDE 
-
-3. On tools tab, follow settings below
-
-```
-Board ➝ ESP32C3 Dev Module
-USB CDC On Boot ➝ Enabled
-CPU Frequency ➝ 160MHz (WiFi)
-Core Debug Level ➝ Info
-Erase All Flash Before Sketch Upload ➝ Enabled (or choose as needed)
-Flash Frequency ➝ 80MHz
-Flash Mode ➝ QIO
-Flash Size ➝ 4MB (32Mb)
-JTAG Adapter ➝ Disabled
-Partition Scheme ➝ Minimal SPIFFS (1.9MB APP with OTA/190KB SPIFFS)
-Upload Speed ➝ 921600
-```
-
-4. Open sketch to compile (File ➝ Examples ➝ AirGradient Air Quality Sensor ➝ OneOpenAir). This sketch for AirGradient ONE and Open Air monitor model
-5. Compile
-
-![compiled esp32](images/compiled.png)
-
-## Steps for ESP8266 based board (DIY model)
-
-1. Add esp8266 board by adding http://arduino.esp8266.com/stable/package_esp8266com_index.json into Additional Board Manager URLs field (File ➝ Preferences ➝ Additional boards manager URLs)
-
-![additional-board](images/additional-board.png)
-
-2. Install esp8266 board on board manager with version **3.1.2** (Tools ➝ Board ➝ Boards Manager ➝ search for `"esp8266"`)
-
-![board manager](images/esp8266-board.png)
-
-3. Install AirGradient library on library manager using the latest version (Tools ➝ Manage Libraries... ➝ search for `"airgradient"`) 
-
-![Aigradient Library](images/ag-lib.png)
-
-4. On tools tab, set board to `LOLIN(WEMOS) D1 R2 & mini`, and let other settings to default
-
-![settings esp8266](images/settings-esp8266.png)
-
-5. Open sketch to compile (File ➝ Examples ➝ AirGradient Air Quality Sensor ➝ `<Model Option>`). Depends on the DIY model, either `BASIC`, `DiyProIndoorV3_3` and `DiyProIndoorV4_2` 
-6. Compile
-
-![compiled esp8266](images/compiled-esp8266.png)
-
-## Possible Issues
-
-### Linux (Debian)
-
-ModuleNotFoundError: No module named ‘serial’
-
-![Linux Failed](images/linux-failed.png)
-
-Make sure python pyserial module installed globally in the environment by executing: 
-
-`$ sudo apt install -y python3-pyserial`
-
-or 
-
-`$ pip install pyserial` 
-
-Choose based on how python installed on your machine. But most user, using `apt` is better.
-
-## How to contribute
-
-The instructions above are the instructions for how to build an official release of the AirGradient firmware using the Arduino IDE. If you intend to make changes that will you intent to contribute back to the main project, instead of installing the AirGradient library, check out the repo at `Documents/Arduino/libraries` (for Windows and Mac), or `~/Arduino/Libraries` (Linux). If you installed the library, you can remove it from the library manager in the Arduino IDE, or just delete the directory.
-
-**NOTE:** When cloning the repository, for version >= 3.3.0 it has submodule, please use `--recursive` flag like this: `git clone --recursive https://github.com/airgradienthq/arduino.git AirGradient_Air_Quality_Sensor`
-
-Please follow github [contributing to a project](https://docs.github.com/en/get-started/exploring-projects-on-github/contributing-to-a-project) tutorial to contribute to this project.
-
-There are 2 environment options to compile this project, PlatformIO and ArduinoIDE.
-
- For PlatformIO, it should work out of the box
- For arduino, files in `src` folder and also from `Examples` can be modified at `Documents/Arduino/libraries` for Windows and Mac, and `~/Arduino/Libraries` for Linux

-**Notes**

- `offlineMode` : the device will disable all network operation, and only show measurements on the display and ledbar; Read-Only; Change can be apply using reset button on boot.
- `disableCloudConnection` : disable every request to AirGradient server, means features like post data to AirGradient server, configuration from AirGradient server and automatic firmware updates are disabled. This configuration overrides `configurationControl` and `postDataToAirGradient`; Read-Only; Change can be apply from wifi setup webpage.
+#### Corrections

-### Corrections
-
-The `corrections` object allows configuring PM2.5, Temperature and Humidity correction algorithms and parameters locally. This affects both the display, local server response and open metrics values.

+*This document to explain local storage mode - experimental*
+
+## How it works?
+
+1. Monitor directly goes to local storage mode
+2. On boot, monitor will attempt to connect to default wifi. And if connected, mdns and local server will be enabled, otherwise it will ignore and continues the measurements
+3. On display, when boot it will show the mode ("local storage mode") and wifi related scenario. After that, monitor will show the measurements dashboard 
+4. Measurement records to the local storage every two minutes that saved on CSV file in SPIFFs partition
+5. Every successful writes, monitor will blink the most left led bar to *blue* twice, but if failed it will blink *red* twice. There are two possibilities for failed write, SPIFFs partition already full or out of heap memory when load the file.
+6. There are 2 endpoinds added for this mode, download measurements from local storage and reset measurement (delete old measurements file and create new one) with new timestamp. Timestamp here to set the monitor system time.
+
+**Notes**
+
+1. Default wifi
+    - ssid ➝ `airgradient`
+    - password ➝ `cleanair`
+2. Maximum measurements file is around 113kb. If assume each measurements is 60 bytes, with write schedule 2 minutes, SPIFFS will be full in around 5 days
+3. WiFi connection attempt on boot wait for 10s before considering timeout
+4. Tips. If monitor not connected to wifi on boot, no need to restart the monitor for reconnection, it will automatically connect to AP once it is available
+
+### Local Storage Endpoinds
+
+*Make sure monitor is connected to AP, and client also connect to it. And change the serial number on the url*
+
+**Download measurements file**
+
+To download measurements file from local storage, just directly access following url on the browser `http://airgradient_aaaaaaaa.local/storage`, and browser should automatically download the file.  
+
+**Reset measurements**
+
+Execute below command in terminal
+
+```sh
+curl -X PUT -H "Content-Type: text/plain" -d '1733431986' http://airgradient_aaaaaaa.local/storage/reset
+```
+
+`1733431986` this data is the time that we want to set monitor system time to. Its in epoch time format and expecting UTC+0 timezone.
+
+To get epoch time, access this url [https://www.unixtimestamp.com/](https://www.unixtimestamp.com/), and click copy button.
