Daikin-Control
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

API System
Daikin original API use REST.
You can use GET http request to retrive informations and POST http request to apply new settings.

Daikin Emura FTXG-L and FVXS 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.
Minimal parameters set
The /aircon/set_control_info has some mandatory parameters, it means that you need to include them in all the requests to this endpoint even if you are not interested in changing those specific values.
These are the mandatory parameters:
powmodestempshumf_ratef_dir
While these are the ones that can be omitted:
advdt*dh*dfr*dfd*b_modeb_stempb_shumb_f_rateb_f_diralert
minimal request example: pow=1&mode=1&stemp=26&shum=0&f_rate=B&f_dir=3
