Using multiple TVs

It is also possible to use multiple TVs with this integration.

Please note, the above provides a minimal example, however, all options areavailable for each individual TV.

Turn on action

Home Assistant is able to turn on a LG webOS Smart TV if you specify an action, like HDMI-CEC or WakeOnLan.

Common for webOS 3.0 and higher would be to use WakeOnLan feature. To use this feature your TV should be connected to your network via Ethernet rather than Wireless and you should enable LG Connect Apps feature in Network settings of the TV instructions (or Mobile App in General settings for older models) (*may vary by version).

On newer models (2017+), WakeOnLan may need to be enabled in the TV settings by going to Settings > General > Mobile TV On > Turn On Via WiFi instructions.

This usually only works if the TV is connected to the same network. Routing the WakeOnLan packet to a different subnet requires special configuration on your router or may not be possible.

Any other actions to power on the device can be configured.

Sources

To obtain complete list of available sources currently configured on the TV, once the webOS TV is configured and linked, while its powered on head to the Developer Tools > States, find your media_player.<name> and use the sources listed in source_list: remembering to split them per line into your sources: configuration.

Change channel through play_media service

The play_media service can be used in a script to switch to the specified TV channel. It selects the best matching channel according to the media_content_id parameter:
