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:
This project aims to provide 2 main things:
The API described by this document have been tested and seems to be working with firmware version from 1.4.3
to 3.3.1
.
The following hardware configurations have been used for testing:
ModelName: Daikin Emura FTXG-L
ModelID: FTXG35LV1BW
WifiControllerID: BRP069A41 4P358711-2C
Software version: 1.4.3
ModelName: Daikin Emura FVXS-F
ModelID: FVXS35FV1B
WifiControllerID: BRP069A42
Software version: 2.6.0
ModelName: Daikin Caldo XRH30
ModelID: FTXTM302V1B
WifiControllerID: BRP069B41
Software version: 1.2.51
If you try new hardware configurations or new firmware versions, please contact me.
Daikin original API use REST.
You can use GET http request to retrive informations and POST http request to apply new settings.

param name : shum
description: represents the target humidity
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.
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:
pow
mode
stemp
shum
f_rate
f_dir
While these are the ones that can be omitted:
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
