Autodiscover and autoconfigure things

This feature is used to allow hardware plugins to create things automatically and place them on the environment map, already configured, like an autodiscovering system. The things will be created and added to the loaded environment the first time their state changes.

How to enable your plugin autodiscovering

Suppose you have some bulbs connected to a relay board; the first time you turn on one of them, Freedomotic generates a new light object and adds it to the map.

In order to do this you only need to send a state change notification for a thing, if this thing doesn’t exist (checking is made on protocol+address values in the event) it is generated, configured and placed on the frontend map.

All the following examples are related to an X10 plugin and the notification of a change from OFF to ON of the x10 device with address A01. Remember to change the values according to your neeeds.

ProtocolRead event = new ProtocolRead(this, "X10", "A01");
event.addProperty("x10.function", "ON"); //this is plugin related, your plugin will have other properties
event.addProperty("object.class", "Light");
event.addProperty("", "My X10 Light");
event.addProperty("object.protocol", "X10");
event.addProperty("object.address", "A01");

More info about these properties:

Property Example Value Description
object.class Light The type of the thing that will be created. It must be a string containing a thing type as you see in the things list menu of java frontend (when you press F6) My Light The name of the new thing. If already exist a numeric ID will be added at the end like My Light 1
object.protocol ProtocolName (OPTIONAL) The name of the protocol used to manage this thing (eg: ZWave)
object.address 1234 (OPTIONAL) The address string (it’s protocol dependent)


Omitting object.class and properties makes the ProtocolRead event to be discarded if no such thing exists. If the thing exists the state change described in the event is applied.
