Question 1

How do I save the authentication key for my LG TV with LGTV2?

Accepted Answer

By default, the library stores keys in system-specific paths (e.g., ~/.lgtv2/ on Linux), but you can override this with a custom saveKey function. After the initial connection, you'll need to accept the prompt on your TV to authorize the app.

Question 2

LGTV2 vs LGTV.js – which one is better for controlling LG TVs?

Accepted Answer

LGTV2 is a fork of LGTV.js, heavily modified for improved integration and features. It's actively maintained and used in projects like Node-RED, so it's generally recommended for new developments, though LGTV.js might be simpler for basic use cases.

Question 3

How to handle errors when the TV is turned off or unreachable?

Accepted Answer

The library emits an 'error' event for connection issues, and it prevents log flooding by emitting subsequent equal errors only once, as noted in the README. You should implement error handling in your callbacks to manage disconnections gracefully.

Question 4

Can I control multiple LG TVs simultaneously with this library?

Accepted Answer

Yes, you can create multiple instances with different URLs for each TV, but each requires its own authentication key and connection management, which might increase complexity in large setups.

Question 5

How to subscribe to mute status changes on an LG TV?

Accepted Answer

Use the subscribe method with the URL 'ssap://audio/getVolume', and in the callback, check the 'muted' field in the response object, as shown in the example code that logs mute changes.

Question 6

Is there a way to simulate mouse clicks or button presses on the TV?

Accepted Answer

Yes, use the getSocket method with URLs like 'ssap://com.webos.service.networkinput/getPointerInputSocket' to get a dedicated socket for sending input events, such as 'click' commands, as detailed in the API section.
