Homekit an LG smart TV 2019 not working

@robertapple1 OMG THANK YOU!!! That worked!

I'm going to go out on a limb and assume that LG is trying to send the input names over to HomeKit, and that one of the names being too long is causing the failure. @Apple Please take note.

When the LG TV is "smart connected" to a cable/sat Set top box (please ignore "remote", its between the TV and the STB), the LG TV names the input based on the provider, which is a long name ("Baltimore Something FIOS Verizon blah blah blah blah Services Something Something").

When the LG TV is "smart connected" to the STB, Adding the LG TV to HomeKit fails ("Home couldn't connect to Accessory" or similar message)

When the LG TV is NOT "smart connected" to the STB, adding the LG TV to HomeKit succeeds just fine.

When the LG TV, after being added to HomeKit, is re-"smart connected" to the STB, the LG TV Accessory in HomeKit becomes unresponsive.

When the "Smart connected" STB input name is re-named on the LG TV to a short name (Home Dashboard -> Edit -> Rename input), and an exists in HomeKit, where previously was "Unresponsive", HomeKit accessory is now responsive.

Conclusion, long input name causes an error in the accessory update/verification process.

Solution: Rename input after its "smart connected" to a short name

I've had the same problem + managed to get it all working at last!

I think my problem was assuming my router didn't have seperate 2.4 / 5ghz frequencies (as I've only ever had one network show

up) but discovered an option, buried deep in the router settings, to separate the channels and disable 5ghz.

I Kicked off all devices connected connected to the 5ghz frequency

Disabled 5ghz on the router + saved the settings.

I reset the TV

Immediately tried connecting via Homekit - it failed

10 mins later, tried just screenmirroring on an MBP, it connected seamlessly.

Tried Homekit again + it then connected.

It probably a bug that all the devices need to be on the same frequency, but it worked for me

Mate, try this, it worked for me after trying literally everything :

• Factory reset your TV, this HAS TO BE DONE, no matter how much it hurts (and trust me, it did as I spent many hours calibrating my TV...)
• after you did that, reboot your iOS device
• make sure you’re using the same WiFi network
• don’t try to connect your TV via HomeKit but instead Airplay any YouTube video for example or Music
• once this worked, use Home App and register your tv normally by using the numbers instead of the scan

Good luck

Hi Enzodima

Unfortunately I changed two things at once but I have got it working now.

i first connected my tv to my router with an Ethernet cable and then pulled the power cable out and left it 15seconds.

After rebooting both HomeKit and Airplay worked straight away. I have remove the Ethernet cable and switched back to WiFi and it is still working.

i think it was probably the power cycle that fixed this for me.

I hope this works for you too

Been struggling with this last few weeks

Today I got it too work at last from suggestion on the av forum.

1) rename TV to shorter name now using just - lg tv

2) changed wifi to 2.4ghz (i do have wired connection not tried using just this)

3) did NOT scan code, but rather put in the numbers directly on iPad/iphone

Once your TV is connected to the set top box (STB) and before you add it to Homekit shorten the name it generated for the input on the TV to a shorter version i called mine "LG TV". I then went to the "Airplay 2 Homekit setup" on the TV and got to the screen where the homekit code is displayed on the screen. Then went to Homekit app on my phone and hit the "+" key in the upper corner and selected "Add Accessory", when the screen showed the camera I pointed it to the code on the TV screen and viola it added it to my Homekit setup.

Hope you have the same success I had.

Happy Holidays

All right guys, I found how to make it work, and trust me I tried everything !

I did what I didn’t want to do which is hard reset my TV because I spent a lot of time calibrating it to my tastes.

After resetting it, I did try to launch airplay via Tidal and it instantly recognized my device. After that I tried to add my LG Tv to HomeKit and again, it worked.

I was about to forbid my TV to join the 5ghz network but it works without doing it, so I suggest you skip this too and leave your router as it is.

it works perfectly and I am a happy man ;-)

Again thanks to all of you guys, I am fresh into this community but love it already.

All the best

This fixed my problem:

Updated Firmware, Changed TV Name to “Living Room TV”, unplugged tv 10 seconds. plugged back in... Screen mirroring and airplay finally worked fine ,,

i have bought 2 days ago an LG OLED C9 MLB

at first when i try to connect the tv HomeKit with my iPhone App did not work, because my iphone was on mobile data, then I switch the wifi on on my iphone, after a few try still not working!

What I realised was my fault because my iPhone supposed to be connected to the same wifi like the tv oled. I connected to the iphone to the same wifi like the tv was connected, then my HomeKit iphone app connected at first time when I scanned the tv barcode HomeKit

You can connect try this YouTube guide how to connect your Tv to Apple HomeKit on your iPhone or Tablet https://youtu.be/02XPy7itkz4

Hey, robertapple1.

I see that you've purchased an LG C9 55 inch Class 4K Smart OLED TV w/ AI ThinQ® (54.6'' Diag). You're trying to connect it as a Home accessory, and I'd like you to contact Apple Support for help.

Apple - Support - Product Selection — After selecting this link, type Homekit in the Search topics field and select "Help with HomeKit certified accessories". Then choose how you'd like to start the conversation.

Take care.

I now agree. Last night I disconnected the magic remote from set top box and now home kit connectivity works great. The strange thing is the magic remote still works great for controlling my Apple TV and my LG 4K Blu-ray player. So why is just set top box an issue? ( magic remote even turned on my electric heater by unintentionally)
