 `limitlessled` can control your [LimitlessLED](http://www.limitlessled.com/) lights from within Home Assistant. The lights are also known as EasyBulb, AppLight, AppLamp, MiLight, LEDme, dekolight, or iLight. 
 
+LimitlessLED bulbs are controlled via groups, so you can only control an individual bulb via the bridge if it is in a group by itself. 
+
+Note: you can assign an `rgbw`, `rgbww`, `white` and `dimmer` group to the same group number, effectively allowing up to 16 groups (4 `rgbww`, 4 `rgbw`, 4 `white` and 4 `dimmer`) per bridge.

 ### {% linkable_title Setup %}
 
-Before configuring Home Assistant, make sure you can control your bulbs or LEDs with the MiLight mobile application. Discover your bridge(s) IP address. You can do this via your router or a mobile application like Fing ([android](https://play.google.com/store/apps/details?id=com.overlook.android.fing&hl=en) or [iTunes](https://itunes.apple.com/us/app/fing-network-scanner/id430921107?mt=8)).

     - **number** (*Required*): Group number (`1`-`4`). Corresponds to the group number on the remote. These numbers may overlap only if the type is different.
     - **name** (*Required*): Any name you'd like. Must be unique among all configured groups.
     - **type** (*Optional*): Type of group. Choose either `rgbww`, `rgbw`, `white`, `bridge-led` or `dimmer`. `rgbw` is the default if you don't specify this entry. Use `bridge-led` to control the built-in LED of newer WiFi bridges.
-    - **fade** (*Optional*): Fade behavior. Defaults to `off`. If turned on, the group is faded out before being turned off. This makes for a more pleasing transition at the expense of wall switch usability, since the light will turn back on at the lowest brightness if it is power cycled.

+### {% linkable_title Night Effect %}
+
+LimitlessLED has a `night` effect that can be used to dim the lights below `brightness: 1`. This night mode is meant to temporarily turn the lights into a nightlight. This mode can be especially helpful when wall switches are also being used. For example, when a light is using the `night` effect one way to return it to its previous brightness level (other than using Home Assistant) is to switch the lights off and then back on from the wall switch.
+
+Note that the `brightness`, `color` and `temperature` attributes cannot be used when using the `night` effect. You can turn on `night` effect by using the `effect` attribute of the normal `light.turn_on` service. Here is an example:
+
+```yaml
+automation:
+  - alias: ...
+    trigger:
+      # ...
+    action:
+      - service: light.turn_on
+        data:
+          entity_id: light.office, light.kitchen
+          effect: night

 - **RGBWW** (Only supported on v6 bridges)
-  - *Color*: There are 25,856 color possibilities along the LimitlessLED color spectrum. For colors, hue and saturation can be used, but not lightness. If you select a color with lightness, Home Assistant will calculate the nearest valid LimitlessLED color. In white mode the temperature can be set.
