<script type="text/x-red" data-help-name="trigger">
<p>When triggered, can send a message, and then optionally a second message, unless extended or reset.</p>
<h3>Inputs</h3>
<dl class="message-properties">
<dt class="optional">reset</dt>
<dd>If a message is received with this property, any timeout or repeat
currently in progress will be cleared and no message triggered.</dd>
</dl>
<h3>Details</h3>
<p>This node can be used to create a timeout within a flow. By default, when
it receives a message, it sends on a message with a <code>payload</code> of <code>1</code>.
It then waits 250ms before sending a second message with a <code>payload</code> of <code>0</code>.
This could be used, for example, to blink an LED attached to a Raspberry Pi GPIO pin.</p>
<p>The payloads of each message sent can be configured to a variety of values, including
the option to not send anything. For example, setting the initial message to <i>nothing</i> and
selecting the option to extend the timer with each received message, the node will
act as a watchdog timer; only sending a message if nothing is received within the
set interval.</p>
<p>If set to a <i>string</i> type, the node supports the mustache template syntax.</p>
<p>If the node receives a message with a <code>reset</code> property, or a <code>payload</code>
that matches that configured in the node, any timeout or repeat currently in
progress will be cleared and no message triggered.</p>
<p>The node can be configured to resend a message at a regular interval until it
is reset by a received message.</p>
<p>Optionally, the node can be configured to treat messages with <code>msg.topic</code> as if they
are separate streams.</p>
