Turns off notification LED at night. Prevents that annoying blinking lights when notification is posted in Your dark room when You sleep!
Improved version. Now works by using shell commands, not interact blocks. Also, as it now checks the current state of LED system setting, it will skip the switch, if for example the LED is already OFF in the evening.
From now on it should work on all phones that have system setting.
