This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Add a simple daydream service that displays a clock and the text from a custom Item. The implementation is kept simple as there might be a screen saver in Android 15 that utilizes the device controls. https://www.androidauthority.com/android-15-home-controls-screensaver-3433352/ Closes openhab#215 Signed-off-by: mueller-ma <[email protected]>
