Apple HomeKit - "No Response" in HomeKit app

[Paesano]

I am having an issue with two of your tv's at my home with Apple HomeKit.  I have a 55 inch and 65 inch OLED C9 TV.  They are both compatible with HomeKit.  Originally when I installed the TV's I had all sorts of issues with Apple HomeKit. For the Last 2 months Apple HomeKit has been working perfect with them.  Now after a recent update to them via automatic updates, Apple HomeKit now has an issue viewing the tv on the HomeKit app remotely while the TV is OFF,  It shows "No Response" in HomeKit.  My TV's are hardwired via Ethernet cable. 

 

There are 4 states in HomeKit that are recognized for the TV:

- Viewing the tv on the HomeKit app locally on the network while the TV is ON (This works in HomeKit and shows the tv as turned on)

- Viewing the tv on the HomeKit app locally on the network while the TV is OFF (This works in HomeKit and shows the tv as turned off)

- Viewing the tv on the HomeKit app remotely while the TV is ON (This works in HomeKit and shows the tv as turned on)

- Viewing the tv on the HomeKit app remotely while the TV is OFF (This DOES NOT work in HomeKit and the TV shows in HomeKit as "No Response")


I've tried reseting the TV's and doing all sorts of things. Nothing has worked.  I believe there is an issue with the latest firmware.

I have the same problem. 
In my house I have 4 LG TV. Only one works perfectly.

All of them are the same configuration, and they are hardwired via Ethernet cable. So I really don't know why just one works.

2019 model - 65SM8600PSA - I can turn it on anywhere, anytime. It has a7 second gen processor.
2020 model - 55NANO86SNA - It's a new model, with te processor a7 third gen. Don't work! Viewing the tv on the HomeKit app remotely while the TV is OFF (This DOES NOT work in HomeKit and the TV shows in HomeKit as "No Response" - Always.
2019model - 49SM8000PSA - Sometimes it works, sometimes it don't work. It has Quadcore processor.
 

Crazy! I don't know what I have to do!

Only way I can resolve no response errors when TV (OLED55E8PTA) is in standby mode is move IOS device running HomeKit app within Bluetooth range,  TV is connected to network via Ethernet cable. Quick Start+ is enabled.  I have a 4K Apple TV within 3 feet of the TV and a HomePod also within Bluetooth range. Once TV is on I can change inputs and turn it off via HomeKit app outside of Bluetooth range.

Resolved for me with 5.30.10. Thanks LG!

I am rather network savvy. I have software running on my LAN that shows what IP addresses and MAC addresses (devices) that are connected. I can see that when I power off my LG 49UN7300PUB LG TV it disconnects from the network. It doesn’t matter whether the connection is via ethernet or WiFI (2.4G or 5G). Well if the TV is not connected to the network Apple Homekit will show the device as “no response” and you won’t be able to turn on the TV via an app either.  I have tried several settings including Quick Start on/off and Mobile Device Management on/off. I have tried a variety of power settings. Everything to no avail. If an LG technician could advise on how to keep the network connection active, it would resolve this issue. I believe it to be a software / firmware issue with the LG TV. So, any guidance here?
