Listen for UDP events from webbrick.
Description
This event handler listens for UDP events that are sent by webbricks. This is one of the event interfaces that connects external hardware with the WebBrick Gateway.
Configuration
<eventInterface module='EventHandlers.WebbrickUdpEventReceiver' name='WebbrickUdpEventReceiver' listenPort='2552'>
</eventInterface>
The listenPort is the local port that we bind to, generally it should not be changed as webbricks cannot send on any other port
