+### Identify cluster LED state
+
+The Identify cluster server supports two identification commands: **Identify**
+and **TriggerEffect**. These commands allow a user to identify a particular
+device. For these commands, the **LED D3** is used.
+
+The **Identify command** will use the **LED D3** to flash with a period of 0.5
+seconds.
+
+The **TriggerEffect command** will use the **LED D3** with the following
+effects:
+
+-   _Blink_ &mdash; flash with a 1 second period for 2 seconds
+-   _Breathe_ &mdash; flash with a 1 second period for 15 seconds
+-   _Okay_ &mdash; flash with a 1 second period for 4 seconds
+-   _Channel change_ &mdash; same as Blink
+-   _Finish effect_ &mdash; complete current effect sequence and terminate
+-   _Stop effect_ &mdash; terminate as soon as possible
