+## Local Server API
+
+From [firmware version 3.0.10](firmwares) onwards, the AirGradient ONE and Open Air monitors have below API available. 
+
+#### Discovery
+
+The monitors run a mDNS discovery. So within the same network, the monitor can be accessed through:
+
+http://airgradient_{{serialnumber}}.local
+
+
+The following requests are possible:
+
+#### Get Current Air Quality (GET)

+
+#### Get Configuration Parameters (GET)
+With the path "/config" you can get the current configuration.
+```json 
+{
+  "country": "TH",
+  "pmStandard": "ugm3",
+  "ledBarMode": "pm",
+  "abcDays": 7,
+  "tvocLearningOffset": 12,
+  "noxLearningOffset": 12,
+  "mqttBrokerUrl": "",
+  "temperatureUnit": "c",
+  "configurationControl": "local",
+  "postDataToAirGradient": true,
+  "ledBarBrightness": 100,
+  "displayBrightness": 100,
+  "offlineMode": false,
+  "model": "I-9PSL",
+  "monitorDisplayCompensatedValues": true
+}
+```
+
+#### Set Configuration Parameters (PUT)
+
+Configuration parameters can be changed with a put request to the monitor, e.g.
+
+Example to force CO2 calibration
+
+ ```curl -X PUT -H "Content-Type: application/json" -d '{"co2CalibrationRequested":true}' http://airgradient_84fce612eff4.local/config ```
+
+Example to set monitor to Celsius
+
+ ```curl -X PUT -H "Content-Type: application/json" -d '{"temperatureUnit":"c"}' http://airgradient_84fce612eff4.local/config ```
+
+ If you use command prompt on Windows, you need to escape the quotes:
+ 
+  ``` -d "{\"param\":\"value\"}" ```
+
+#### Avoiding Conflicts with Configuration on AirGradient Server
+If the monitor is set up on the AirGradient dashboard, it will also receive configurations from there. In case you do not want this, please set `configurationControl` to `local`. In case you set it to `cloud` and want to change it to `local`, you need to make a factory reset.

+## OTA Updates
+
+From [firmware version 3.1.1](https://github.com/airgradienthq/arduino/tree/3.1.1) onwards, the AirGradient ONE and Open Air monitors support over the air (OTA) updates. 
+
+#### Mechanism
+
+Upon compilation of an official release the git tag (GIT_VERSION) is compiled into the binary.
+
+The device attempts to update to the latest version on startup and in regular intervals using URL
+
+http://hw.airgradient.com/sensors/{deviceId}/generic/os/firmware.bin?current_firmware={GIT_VERSION}
+
+If does pass the version it is currently running on along to the server through URL parameter 'current_firmware'. 
+This allows the server to identify if the device is already running on the latest version or should update.
+
+The following scenarios are possible
+
+1. The device is already on the latest firmware. Then the server returns a 304 with a short explanation text in the body saying this.
+2. The device reports a firmware unknown to the server. A 400 with an empty payload is returned in this case and the update is not performed. This case is relevant for local changes. The GIT_VERSION then defaults to "snapshot" which is unknown to the server.
+3. There is an update available. A 200 along with the binary data of the new version is returned and the update is performed.
+
+More information about the implementation details are available here: https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/system/ota.html

+This is the code for the AirGradient DIY BASIC Air Quality Monitor with an D1
+ESP8266 Microcontroller.
+
+It is an air quality monitor for PM2.5, CO2, Temperature and Humidity with a
+small display and can send data over Wifi.
+
+Open source air quality monitors and kits are available:
+Indoor Monitor: https://www.airgradient.com/indoor/
+Outdoor Monitor: https://www.airgradient.com/outdoor/
+
+Build Instructions:
+https://www.airgradient.com/documentation/diy-v4/
+
+Please make sure you have esp8266 board manager installed. Tested with
+version 3.1.2.
+
+Set board to "LOLIN(WEMOS) D1 R2 & mini"
+
+Configuration parameters, e.g. Celsius / Fahrenheit or PM unit (US AQI vs ug/m3)
+can be set through the AirGradient dashboard.

-/*
-This is the code for the AirGradient DIY BASIC Air Quality Monitor with an D1
-ESP8266 Microcontroller.
-
-It is an air quality monitor for PM2.5, CO2, Temperature and Humidity with a
-small display and can send data over Wifi.
-
-Open source air quality monitors and kits are available:
-Indoor Monitor: https://www.airgradient.com/indoor/
-Outdoor Monitor: https://www.airgradient.com/outdoor/
-
-Build Instructions:
-https://www.airgradient.com/documentation/diy-v4/
-
-Following libraries need to be installed:
-“WifiManager by tzapu, tablatronix” tested with version 2.0.16-rc.2
-"Arduino_JSON" by Arduino version 0.2.0
-"U8g2" by oliver version 2.34.22
-
-Please make sure you have esp8266 board manager installed. Tested with
-version 3.1.2.
-
-Set board to "LOLIN(WEMOS) D1 R2 & mini"
-
-Configuration parameters, e.g. Celsius / Fahrenheit or PM unit (US AQI vs ug/m3)
-can be set through the AirGradient dashboard.
-

+This is the code for the AirGradient DIY PRO 3.3 Air Quality Monitor with an D1
+ESP8266 Microcontroller.
+
+It is an air quality monitor for PM2.5, CO2, Temperature and Humidity with a
+small display and can send data over Wifi.
+
+Open source air quality monitors and kits are available:
+Indoor Monitor: https://www.airgradient.com/indoor/
+Outdoor Monitor: https://www.airgradient.com/outdoor/
+
+Build Instructions:
+https://www.airgradient.com/documentation/diy-v4/
+
+Please make sure you have esp8266 board manager installed. Tested with
+version 3.1.2.
+
+Set board to "LOLIN(WEMOS) D1 R2 & mini"
+
+Configuration parameters, e.g. Celsius / Fahrenheit or PM unit (US AQI vs ug/m3)
+can be set through the AirGradient dashboard.

+/*
+This is the code for the AirGradient DIY PRO 4.2 Air Quality Monitor with an D1
+ESP8266 Microcontroller.
+
+It is an air quality monitor for PM2.5, CO2, Temperature and Humidity with a
+small display and can send data over Wifi.
+
+Open source air quality monitors and kits are available:
+Indoor Monitor: https://www.airgradient.com/indoor/
+Outdoor Monitor: https://www.airgradient.com/outdoor/
+
+Build Instructions:
+https://www.airgradient.com/documentation/diy-v4/
+
+Please make sure you have esp8266 board manager installed. Tested with
+version 3.1.2.
+
+Set board to "LOLIN(WEMOS) D1 R2 & mini"
+
+Configuration parameters, e.g. Celsius / Fahrenheit or PM unit (US AQI vs ug/m3)
+can be set through the AirGradient dashboard.

-This is the code for the AirGradient Open Air open-source hardware outdoor Air
-Quality Monitor with an ESP32-C3 Microcontroller.
-
-It is an air quality monitor for PM2.5, CO2, TVOCs, NOx, Temperature and
-Humidity and can send data over Wifi.
-
-Open source air quality monitors and kits are available:
-Indoor Monitor: https://www.airgradient.com/indoor/
-Outdoor Monitor: https://www.airgradient.com/outdoor/
-
-Build Instructions:
-https://www.airgradient.com/documentation/open-air-pst-kit-1-3/
-
-The codes needs the following libraries installed:
-“WifiManager by tzapu, tablatronix” tested with version 2.0.16-rc.2
-"Arduino_JSON" by Arduino Version 0.2.0
-
-Please make sure you have esp32 board manager installed. Tested with
-version 2.0.11.
-
-Important flashing settings:
- Set board to "ESP32C3 Dev Module"
- Enable "USB CDC On Boot"
- Flash frequency "80Mhz"
- Flash mode "QIO"
- Flash size "4MB"
- Partition scheme "Default 4MB with spiffs (1.2MB APP/1,5MB SPIFFS)"
- JTAG adapter "Disabled"
