ha-smartthinq-sensors Fan speed control is exposed via HomeKit but does not change fan speed

Describe the bug

I have had my WH21SL-18 wired up with Home Assistant for about 6 months now and working well.

However, the "fan speed" control exposed to HomeKit (using the below configuration.yml snippet) doesn't do anything.

I can change the slider in HomeKit (even all the way down to 0%), but this change is not reflected in Home Assistant nor propagated to the air conditioner.

IMG_CB9B4565BEF2-1

homekit:
  - name: Living room
    filter:
      include_entities:
        - climate.living_room_a_c
        - switch.living_room_a_c_jet_mode
        # ...

device.json

Expected behavior Changing the fan speed in HomeKit should change the fan speed of the device (HomeKit uses a fan speed %, but other climate integrations will map these percentage rages to discrete Low/mid/high etc modes).

To handle Auto ("NATURE") fan speed, a boolean switch might need to be exposed, as I am not aware of any way for Apple's slider interface to expose this.

Screenshots If applicable, add screenshots to help explain your problem.

Environment details:

Environment (HASSIO, Raspbian, etc): HassOS
Home Assistant version installed: 2023.5.4
Component version installed: latest
Last know working version: never noticed it working, but I haven't always tried to use set fan speed via HomeKit
LG device type and model with issue: split system WH21SL-18
LG devices connected (list): none other

Output of HA logs

The ThinQ logs which show up when changing fan mode seem to indicate that it is using lowercase speed names:

Additional context

I'm not sure if the high/low/etc is statically defined within HomeKit, are the expected standard names in Home Assistant, or something that each climate integration has to define in a way that HomeKit can find. I couldn't get it to trigger a mid but my old climate system did, so that makes me think it is some kind of changeable mapping.

i have the same issue

Jun 17 '23 20:06 icces

Same issue for me as well

Jun 23 '23 08:06 AngelMonky

@bjeanes so I followed your great comment about them being lower case and made some changes to ac.py and now it works

in class ACFanSpeed(Enum) changed all of LOW-MID-HIGH words to lower case

still needs some work to do (homekit doesn't have mid, 50% is low, anything higher is high) Screenshot 2023-06-26 090826

**Update Now works almost perfect

@kparmun how you changed this on home assistant ?

Jun 27 '23 14:06 icces

@icces you need an add-on like "Studio Code Server" to access these files and edit them after installing the add-on you need to find ac.py which is located in "custom_components/smartthinq_sensors/wideq/devices/" Edit and save it, then restart the home assistant

homekit integration does't accept "Mid", so our three speeds would be off (low) low (mid) high (high)

Jun 27 '23 14:06 kparmun

@kparmun Okay and then what exactly should I change there? is it possible that you provide me with the configuration and I copy and paste it?

Jun 27 '23 14:06 icces

@icces just replace Class ACFanSpeed with this:

class ACFanSpeed(Enum): """The fan speed for an AC/HVAC device."""

slow = "@AC_MAIN_WIND_STRENGTH_SLOW_W"
slow_LOW = "@AC_MAIN_WIND_STRENGTH_SLOW_LOW_W"
off = "@AC_MAIN_WIND_STRENGTH_LOW_W"
LOW_MID = "@AC_MAIN_WIND_STRENGTH_LOW_MID_W"
low = "@AC_MAIN_WIND_STRENGTH_MID_W"
MID_HIGH = "@AC_MAIN_WIND_STRENGTH_MID_HIGH_W"
high = "@AC_MAIN_WIND_STRENGTH_HIGH_W"
POWER = "@AC_MAIN_WIND_STRENGTH_POWER_W"
AUTO = "@AC_MAIN_WIND_STRENGTH_AUTO_W"
NATURE = "@AC_MAIN_WIND_STRENGTH_NATURE_W"
R_LOW = "@AC_MAIN_WIND_STRENGTH_LOW_RIGHT_W"
R_MID = "@AC_MAIN_WIND_STRENGTH_MID_RIGHT_W"
R_HIGH = "@AC_MAIN_WIND_STRENGTH_HIGH_RIGHT_W"
L_LOW = "@AC_MAIN_WIND_STRENGTH_LOW_LEFT_W"
L_MID = "@AC_MAIN_WIND_STRENGTH_MID_LEFT_W"
L_HIGH = "@AC_MAIN_WIND_STRENGTH_HIGH_LEFT_W"

@kparmun Okay now I have changed to your config. but now Im not able to see the fan speed control in my apple home app. I can only change the temperature and the ac starts MID

Jun 27 '23 14:06 icces

@icces maybe this config is not compatible with your model, it's working for me on LW8017ERSM

Jun 27 '23 14:06 kparmun

@kparmun thank you very much!!!! now it works for me!!! I needed the dots in the config file and now it works!!

if I now select the smallest level in HomeKit, it is incorrectly displayed to me as "Off". is it possible to display maybe 10%?

Jun 27 '23 17:06 icces

@icces that is a "HomeKit Bridge" limitation, the documents says that bridge only understands "off,low,high" Screenshot 2023-06-27 143331 it only has 3 modes

I'm new to home assistant so I'm not sure, but I think unless there's a way that we can tinker with Homekit Bridge code, there's nothing we can do about this

Jun 27 '23 18:06 kparmun

I think the example there is just what happens if speed_list has 3 values. I think it can have more, but the first one should always be a sentinel for "off". I think it could have [off, low, mid, high, jet], for instance.

Jun 27 '23 23:06 bjeanes

@bjeanes I thought so too, and by that logic [off,mid,high] should work but it doesn't It only works with these three words [off,low,high], I tested it and it doesn't matter that you start with [off] you can only use [low,high] and it still works No matter what I do it only accepts those 3 words, nothing else

Jun 27 '23 23:06 kparmun

Found out that homekit keys are [off, low, middle, medium, high] but it didn't change much But at least it doesn't show Off in home app anymore This is what I got now:

class ACFanSpeed(Enum): """The fan speed for an AC/HVAC device."""

slow = "@AC_MAIN_WIND_STRENGTH_SLOW_W"
slow_low = "@AC_MAIN_WIND_STRENGTH_SLOW_LOW_W"
low = "@AC_MAIN_WIND_STRENGTH_LOW_W"
LOW_MID = "@AC_MAIN_WIND_STRENGTH_LOW_MID_W"
middle = "@AC_MAIN_WIND_STRENGTH_MID_W"
MID_HIGH = "@AC_MAIN_WIND_STRENGTH_MID_HIGH_W"
high = "@AC_MAIN_WIND_STRENGTH_HIGH_W"
POWER = "@AC_MAIN_WIND_STRENGTH_POWER_W"
AUTO = "@AC_MAIN_WIND_STRENGTH_AUTO_W"
NATURE = "@AC_MAIN_WIND_STRENGTH_NATURE_W"
R_LOW = "@AC_MAIN_WIND_STRENGTH_LOW_RIGHT_W"
R_MID = "@AC_MAIN_WIND_STRENGTH_MID_RIGHT_W"
R_HIGH = "@AC_MAIN_WIND_STRENGTH_HIGH_RIGHT_W"
L_LOW = "@AC_MAIN_WIND_STRENGTH_LOW_LEFT_W"
L_MID = "@AC_MAIN_WIND_STRENGTH_MID_LEFT_W"
L_HIGH = "@AC_MAIN_WIND_STRENGTH_HIGH_LEFT_W"
