 - State:
 	- <String, Object>, set a state key to a value. Will trigger the 'State' special event if the value changed.
 
+
+For example you could do something like:
+
+- At 22:59 => Set Ringtone volume to 0%
+- At 7:59 => Set Ringtone volume to 100%
+
+or achieve the same thing with states:
+
+- Between 22:59 and 7:59 => Set state 'sleepy' to true
+- On 'sleepy' change to true => Set volume to 0% 
+- On 'sleepy' change to false => Set volume to 100%
