Switching AC on and setting a temperature at the same time doesn't work

[kwridan]

Describe the bug

I have an LG duct AirCon configured in homeassitant via this integration and exposed to HomeKit. When the AC is off, attempting to switch it on via HomeKit successfully switches it on, however doesn't respect the temperature selected (it defaults to 24℃), manually changing the temperature subsequently works.

Expected behavior The temperature selected should be respected.

Screenshots n/a

Environment details:

• Environment (HASSIO, Raspbian, etc):
• Home Assistant version installed: 2024.6.0
• Component version installed: v0.39.2
• Last know working version: n/a
• LG device type and model with issue: DUCT_626301_WW-DUCT
• LG devices connected (list):

Additional context

Testing this a bit further, it might not be specific to HomeKit, manually invoking the service in home assistant to set the temperature and hvac mode when the AC is switched off results in the same behaviour where the temperature defaults to 24℃ just doesn't produce the error above.

service: climate.set_temperature
target:
  device_id: #...<device-id>
data:
  temperature: 22.5
  hvac_mode: cool

Could it be that the ThinQ API doesn't support setting the hvac mode and temperature at the same time?

Thanks! 🙏
