AC display light switch not working

[gabi1324]

Describe the bug Hello! I have a problem with the display light on an S09ET AC unit. The switch is always off and if I toggle it the unit beeps but doesn't do anything. I can control the light from the remote but not from the LG app.

Expected behavior control the display light from HA

please test last release and let me know if switch logic is correct for all.

Logic is inverted for me now. (v0.35.1) Also: if the unit is off light switch is on[1], toggling does nothing but a beep.

Edit: 1. The switch in on with the unit off at startup, after that it respects the (inverted) state.

please test last release and let me know if switch logic is correct for all.

Now everything works fine... the switch matches the real state of the display (v0.35.2).

Diagnostic files:

• DISPLAY OFF.json
• DISPLAY ON.json

Also: if the unit is off light switch is on, toggling does nothing but a beep.

This is because the setting is being changed successfully, but the display on some conditioners will only be limited if the conditioner is operating.

Hey @ldotlopez, version 0.35.2 was released which corrected this inversion for me, your diagnostic files show version 0.35.1, can you confirm if updating to version 0.35.2 makes any changes?

Thanks @dougiteixeira, I missed that second update.

It works OK now

@ollo69 latest version works like a charm for me, thank you very much for looking into this! Bought you some coffee

For me no change. Unable to adjust the display. There is a beep but no change.

[ollo69]

@elpigeondindo,

may be this doesn't work for all devices, but attach device diagnostics so I can check if exist some difference with known working devices.

[elpigeondindo]

@ollo69 Okay but how i can do this?

[ollo69]

Go on integration page and select download diagnostic.

[elpigeondindo]

thanks. i do it

Hi! I can confirm that everything is OK now, on displays with correct and on displays with inverted logic. Thanks a lot!

[ollo69]

@elpigeondindo,

I checked your diagnostic but it is identical to the others, so I have no idea why is not working for you.

[ollo69]

I close this issue, everything should be done was done. If there are other issue or request please open a new thread.

Just adding this here for people looking for a way arround with the model RAC_056905_WW. I could not find the fix, but just a diagnosis. Although API is not working, when you press the light button on the IR controller, the state of the light changes when looking at the snapshot: 'airState.lightingState.displayControl': 0.0 = lights on 'airState.lightingState.displayControl': 1.0 = lights off But when you send the command (Setting new state for device XXXXX: basicCtrl - Set - airState.lightingState.displayControl - 1 or Setting new state for device XXXXX: basicCtrl - Set - airState.lightingState.displayControl - 0) nothing happens, just the beep sound. I guess the AC can show the light state, but cannot change it through API. That´s a big bummer, cause this AC is on my toddler's room and having that hability would've been awesome.

Kind of random, but kind of related, has anyone tried to disabled the beeping sound? Some remotes have that option but mine doesn't assume AC doesn't support disabling the beeping 😔

[ollo69]

@All,

this was already discussed a lot. The light control is there (exactly the same used by other integration) but not all AC device support this control via API. There is nothing that I can do, if the integration control just make a beep and nothing change means that the control doesn't work and the only thing you can do is disable it.

Since I don't believe we'll ever get these functions added by LG let me share how I've modded the units around my house to solve those problems. For the beeping sound just take the cap of the piezo beeper and remove the metal disc (save it for a later date should you ever feel nostalgic). For he display, I've taped some aluminium tape on top of the display and it dims the light enough for it to be used on our son's bedroom.
