 The Halo can currently only be added through Zeroconf discovery. Afterwards, add a configuration to the Halo by entering the options by pressing the `CONFIGURE` button.
 
+All actions have to be manually defined for each entity type, which is why not all entities work at this point.
+
+Generally "wheel" events are handled by counting the number of detents in a "rotation" with a resetting timeout of currently 125ms and acting accordingly. This means that an action is called only when the wheel has been stationary for 125ms. This seems to be the most stable way to handle entities that are "slow" to change states.
