Automatically extend LG WebOS Developer Mode with Home Assistant

README.md

The Developer Mode app is required for testing apps in LG's WebOS. The developer mode lasts only 50 hours, and the app has a button to reset the timer back to 50. This Home Assistant automation will turn on the TV, open the Developer Mode app, press the "extend" button, and turn the TV back off. Here I set it to run automatically every night at 4 AM.

Important to note that the media_player.webos_tv in these files refers to the entity ID in my own configuration. You need to replace it with your TV's entity ID defined in Home Assistant.
