+Change Public Address Command
+=============================
+
+	Command Code:		0x0031
+	Controller Index:	<controller id>
+	Command Parameters:	Address (6 Octets)
+	Return Parameters:
+
+	This command allows changing the public address. Since a vendor
+	specific procedure is required, this command might not be supported
+	by all controllers. Actually most likely only a handful embedded
+	controllers will offer support for this command.
+
+	It is only possible to change the public address when the
+	controller is powered off.
+
+	When this command succeeds, the current controller index will
+	become invalid and an Index Removed event will be send. Once
+	the address has been successfully changed an Index Added event
+	will be send. There is no guarantee that the controller index
+	stays the same.
+
+	All previous configured parameters and settings are lost when
+	this command succeeds. The controller has to be treated as new
+	one. Use this command only when you really know what you are
+	doing.
+
+	This command generates a Command Complete event on success or a
+	Command Status event on failure.
+
+	Possible errors:	Rejected
+				Not Supported
+				Invalid Parameters
+				Invalid Index
