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:
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
It seems that this settings doesn't actually change led.
param name: led
| value | desc |
|---|
- | set to '0' (same as '0' value) 0 | ? 1 | ?

/common/get_datetime
the meaning is obvious and the response I got was: ret=OK,sta=2,cur=2016/7/7 21:23:28,reg=eu,dst=1,zone=313
/aircon/get_scdltimer_info
it seems to get informations about the tasks scheduled on the AC, I have no further informations on that at the moment, but the response I got without anything scheduled was: ret=OK,format=v1,f_detail=total#18;_en#1;_pow#1;_mode#1;_temp#4;_time#4;_vol#1;_dir#1;_humi#3;_spmd#2,scdl_num=3,scdl_per_day=6,en_scdltimer=1,active_no=1,scdl1_name=,scdl2_name=,scdl3_name=
/aircon/get_scdltimer_body&target=1
this seems to get detailed informations about a specific scheduled task, and the response I got was: ret=OK,format=v1,target=1,en_scdltimer=1,moc=0,tuc=0,wec=0,thc=0,frc=0,sac=0,suc=0
/aircon/get_day_power_ex?days=2
this command retrieves the power consumption (in 0.1 kWH) of the last 2 days, separated hour by hour starting from midnight and also separated for cooling and heating. The days variable can be set up to 7 for last 7 days. The response I got was: ret=OK,curr_day_heat=0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0,prev_1day_heat=0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0/0,curr_day_cool=0/0/0/0/0/0/0/0/0/0/0/0/1/0/0/0/0/2/2/2/2/0/0/0,prev_1day_cool=0/0/0/0/0/0/0/0/0/0/0/0/0/1/0/0/0/2/2/2/1/2/1/0
/aircon/get_week_power_ex
this command retrieves the power consumption (in 0.1 kWh) of the current and last week, separated day by day, the response I got was: ret=OK,s_dayw=4,week_heat=0/0/0/0/0/0/0/0/0/0/0/0/0/0,week_cool=10/11/3/9/10/16/11/3/9/6/6/0/0/0
/aircon/get_year_power_ex
this command retrieves the power consumption (in 0.1 kWh) of the current and last year, separated month by month, the response I got was: ret=OK,curr_year_heat=0/0/0/0/0/0/0/0/0/0/0/0,prev_year_heat=0/0/0/0/0/0/0/0/0/0/0/0,curr_year_cool=0/0/0/0/0/24/70/0/0/0/0/0,prev_year_cool=0/0/0/0/0/0/0/0/0/0/0/0
/aircon/set_special_mode?en_streamer=0
this command disables the ion streamer on the AC (or it enables substituting ?en_streamer=1). The response has the form: ret=OK,adv=13 or ret=OK,adv= where '13' means that the streamer has been activated or '' means that it has been deactivated
/aircon/set_special_mode?set_spmode=1&spmode_kind=1
this command enables the power mode of the AC and this can be seen looking at the adv=2 return message (even in the get_control_info)
/aircon/set_special_mode?set_spmode=1&spmode_kind=2
this command enables the econo mode of the AV and this can bee seen looking at the adv=12 return message (even in the get_control_info)
/aircon/set_special_mode?set_spmode=0&spmode_kind=1
this command disables the power mode of the AC (I think it also works without the spmode_kind variable and also that it also disable the econo mode, but I haven't checked so far)
