LG Webos TV support for AN-MR23GA remote style

[johnsclarke]

I have adapted one of the Homatic remotes to give a reasonable approximation of an AN-MR23GA style LG remote. A screen shot of what has been produced is shown below. It is a full card that has been added to the Device Family tree as a new option (LG). It only supports the Default Remote style of "Magic Remote 23 GA". It requires a working LG webos TV integration. The TV associated with integration can have up to 4 HDMI inputs.

The Magic Remote's on screen "mouse" functions have not been replicated. It is also not possible to do an exact one-for-one copy of the LG remote as the LG webos TV integration doesn't support (as near as I can tell at least) two of the buttons on this remote. These two buttons are the Option button (the three dots button above the channel up-down buttons) and the Input button (below the channel up-down buttons). The Options button has been converted to the CC button. The Input button's function has been changed to switch the TV's input back to live TV (the antenna input). The standard AN-MR23GA has 6 quick launch buttons. I have increased this to 8 to allow additional HDMI inputs and to allow for the missing Input button limitation. Button overrides are also supported.

What I have written seems to work reasonably well and would probably be best placed to be folded into the main project. I have left the structure of the code in the main project alone as far as possible. My HTML skills are also not great so what has been produced could also be polished a bit more. Let me know how to proceed. I similarly will not be able to maintain a fork of the project for health reasons.
