<p>You can enter the ID (1, 2, ...) of a Lamp and turn it ON or OFF and also set its color. </p><p>By setting the status to AUTO, you can set the ON/OFF status as a message payload (e.g., msg.payload="ON") and the color through the message topic (e.g., msg.topic="EBF5FF") on the node input. Please note, in case you use both, the status selection overides the msg.payload!</p><p>Also, if you pass something like msg.payload="ALERT" the Lamp will flash once.</p> <p>You can enter the ID (1, 2, ...) of a Lamp and turn it ON or OFF, set the color and the brightness (0->100). </p><p>By setting the status to AUTO, you can set the lamp parameters using the message on the input node as follows:</p>
<ul>
<li>msg.lamp sets the lamp ID</li>
<li>msg.color sets the lamp color (e.g., msg.color="DF0101" will set the color to red)</li>
<li>msg.brightness sets the lamp brightness (e.g., msg.brightness=50)</li>
<li>msg.payload is used to se the lamp status (on/off/alert) (e.g., msg.payload="alert" will flash the Lamp once</li>
</ul>
<p>Please note, by setting the status to AUTO on the node configuration, the rest of the node parameters are ignored, you need to set all parameters through the message input.</p>
