<p>Pressing the button on the left side of the node allows a message on a topic to be injected into the flow. This is mainly for test purposes.</p>
|

<p>If no payload is specified the payload is set to the current time in millisecs since 1970. This allows subsequent functions to perform time based actions.</p>
|
||||
<p>The repeat function does what it says on the tin and continuously sends the payload every x seconds.</p>

<p>The Fire once at start option actually waits 50mS before firing to give other nodes a chance to instantiate properly.</p>
