Describe the bug
A clear and concise description of what the bug is.
With the new update of homepodOS/ios 15.4 there have been a few bugs I have encountered.

• Siri now constantly asks "to which value" when trying to change modes from Auto, Heat, Cool, as well as when turning On or Off.
• Siri cannot change the temperature now because siri cannot detect the temperature control but this works when I manually use the home app. Siri responds with your A/C does not support temperature control when previously before the os updates this command works.
• Before the update siri can detect the room temperature because the A/C supports it but after the update siri does not anymore so automations now fail.

Symptom check

• Does your unit appear in the Home app?
  Yes
• Is the current on/off state, temperature, and mode being reported?
  Yes
• Does your unit respond to the controls?
  Yes

Same issue here with an LG JW-Q18WUZA.THLG1 (1.5 Ton Window AC)

Had the same issue here. Downgrading to homebridge-lg-thinq-ac v2.2.0 resolve the issue.
For more, I don't think it's a iOS issue. In HomebridgeUI > Accessories, I wasn't able to change the temp. No particular logs.
2,2,0 works as expected now.

It is definitely a problem even under 2.2.0 and a quick web search shows that this is an ios problem, not a problem with this homebridge plugin - it has been reported for numerous devices (I saw it for ACs and blinds). Some phrasings will not even get you the "to which value" - I managed to get there by saying "change heating" rather than "change heatpump" (loose translation - this was in French). If you get to the "to which value" prompt, try changing the phrasing of your answer. In my case, there is a specific variation around "23 degrees" or "23 degrees celcius" or "23 Celcius" that does work.

Do you have any other Homebridge A/C plugins by chance?

This plugin is built on the Homebridge platform, which provides all of the HomeKit / Siri connections. If the started with the iOS 15.4 update, this is likely either an iOS 15.4 or Homebridge platform bug that will need to be solved upstream, unfortunately

[IMNotMax]

@astroleptirobot you're right (nice nickname btw, Frenchy here) some phrasing issues with iOS 15.
And the downgrade does not resolve.
But I had issue with the latest version to control the AC in the Home App and homebridge which is now resolved.
About the phrasing, I hope the next beta(s) will correct the use case.

[astroleptirobot]

In 15.4 Siri also has phrasing issues with my August smart lock btw, which I use directly through Homekit (no homebridge involved). @IMNotMax thanks, I've had it forever, used to be my Quake and UT handle. :)

[IMNotMax]

@astroleptirobot do you use Siri in French or English ? For the moment I did not notice any other issue but the temperature of the AC in French.

[astroleptirobot]

In French - but the other reports I've seen (e.g. with blinds and AC units) are happening in English.

[astroleptirobot]

So for me this is now resolved as of the 15.5 update to ios.

Yes for me too

[IMNotMax]

Agree. Same here HomePods mini 15.5 works in French to adjust temperature of the AC.
