https://devzone.nordicsemi.com/f/nordic-q-a/24541/adding-another-led-to-a-server-node-in-light-control-mesh-exampleHi, I would like to control 2 LEDs independantly with the same server node. Should I try to [1] add a element with the same simple on/off model in that server node OR [2] modify the simple on/off model to add another LED control in that model.

However, you create a <em>new</em> model that is a <em>Light fixture model</em> controlling two+ lights. Still, I&#39;d recommend this to span multiple elements (have a look at the more complex lighting models in the <a href="https://www.bluetooth.com/specifications/mesh-specifications">Bluetooth Mesh model specification</a>). The general idea is that it&#39;s the <strong>element</strong> that holds the <strong>state</strong> and the <strong>model</strong> operates on it.</p> <p>Best,<br /> Thomas</p><div style="clear:both;"></div>
