The '''Daikin Emura FTXG-L''' air conditioner comes with a wifi module preinstalled that allows you to control it via internet. The solution provided by Daikin is a mobile app (very well designed) that allows you to control the air conditioner even remotely, exploiting the REST API of the wifi module.

Even if the system works, there are some problems:

• It is no possible to control the AC from a web browser. You must use the official mobile application. If your device is not supported or you are from a computer you can not control your air conditioner over the internet.
• To control your AC remotely from outside your lan, your requests must go through the Daikin server. The device response is slow because the system is based on polling request. (you can't set the ip of the AC on the mobile application)
• Even if the remote management system involves the use of an account with password, there is a big security issue, password and username can be accessed from inside your LAN with a GET request. (try basic_info request)

This project aims to provide 2 main things:

• unoffcial documentation of Daikin API needed to control the air conditioner
• web interface to manage air conditioner settings

##Tested Hardware

Throughout this document is to be considered valid for the following hardware configuration

ModelName:          Daikin Emura FTXG-L
ModelID:            FTXG35LV1BW
WifiControllerID:   BRP069A41 4P358711-2C
Software version:   1.4.3

Please contact me if you try new configurations.

##API System

Daikin original API use REST.

You can use GET http request to retrive informations and POST http request to apply new settings.

##Parameters

###"/common/set_control_info"

####Power param name : pow

description: represents the power state of the device

####Mode param name : mode

description: represents the operating mode

####Temp param name : stemp

description: represents the target temperature

general accepted range 10-41

device memorize last target temp state for each mode under dft* (dft1,dft2...) parameters. You can't set directly these.

####Fan rate param name : f_rate

description: represents the fan rate mode

device memorize last fan rate state for each mode under dfr* (dfr1,dfr2...) parameters. You can't set directly these.

####Fan direction param name : f_dir

description: represents the fan direction

device memorize last fan rate state for each mode under dfd* (dfd1,dfd2...) parameters. You can't set directly these.

####Humidity param name : shum

description: represents the target humidity

Daikin Emura FTXG-L does not support humidity related functionality.

device memorize last humidity state for each mode under dh* (dh1,dh2...) parameters. You can't set directly these.

Posting to set_control_info you can omit these param:

• adv
• dt*
• dh*
• dfr*
• dfd*
• b_mode
• b_stemp
• b_shum
• b_f_rate
• b_f_dir
• alert

minimal request example: pow=1&mode=1&stemp=26&shum=0&f_rate=B&f_dir=3

###"/common/set_led" ####Led It seems that this settings doesn't actually change led.

param name: led

• | set to '0' (same as '0' value) 0 | ? 1 | ?

##Unsupported settings This list show which hardware functionality are not supported by API

• led brightness switch
