<p>Relays are Normally Open switches that can be turned on, off, or toggled.</p>
<p>Send "off" to this node to open the contact (turn load off).</p>
<p>Send "on" to this node to close the contact (turn load on).</p>
<p>Send "toggle" to toggle the relay.</p>
<p>Send "state" to read the state of the relay.</p>
<p>The node will send the relay's new state to it's output (1 for "on", 0 for "off")</p>
<p>The POWERplate24 onboard fan is a special case: use "on", "off", or "state" to control fan.</p>
