LG TV via Serial
lg_tv_rs232
The LG TV via Serial integration lets you control LG TVs by connecting to their RS-232 serial port. Because Home Assistant talks straight to the TV, control is local, fast, and works on TVs without smart features or a network connection.
In Apple Home through HomeKit Bridge
What HomeKit Bridge makes of each kind of entity this integration creates, read from its source code. A device only gets the ones that apply to it.

| LG OLED55B7A | Works Local | Power, inputs and volume over RS-232; many LG TVs ignore power-on in standbySaved copySupported devices: LG OLED55B7A. Limitations: Many LG TVs ignore the power-on command over RS-232 while the set is in standby. If turning the TV on does not work, you might have to disable a power saving mode. Different LG models support different subsets of the RS-232 command set, so some input sources may not be selectable on every TV. If the TV is configured to route audio to an external output (such as optical or HDMI ARC) instead of the TV speakers, the volume controls are not shown for the media player.
