My suggestion for you is to get familiar with how the heartbeat would work. I have created and example <a href="https://devzone.nordicsemi.com/f/nordic-q-a/39270/ble-mesh-heartbeat-example">here </a>that the provisioner enable heartbeat on the node. You can study the example and implement the same on the PyACI interface.&nbsp;</p> <p>We will continue on the other case that you created.&nbsp;</p><div style="clear:both;"></div>
