Zigbee specification doesn’t define this. If your ZTool acts as coordinator, you can implement your devices to send heart beat message to coordinator periodically to know the device online or offline.

It can be any ZCL state report. For example, if it’s light device, you can do periodic ZCL on/off state reporting to coordinator. If coordinator doesn’t receive reporting from light device for a predefined period, you can judge it as offline.

If you fried my approach, the device is offline when it doesn’t report anything for a specific period. Otherwise, it’s online. For showing online/offline status, I suppose that’s about UI design and nothing to do with Zigbee application.

Hi Praveen,

If you are building the node firmware, then you can add the Poll Control Cluster to define a check-in interval which you can control and monitor through the MT API AF_DATA_REQUEST and AF_INCOMING_MSG. Please see the following SimpleLink Academy Lab for more details (context outside of ZNP interfacing). Most ZDO_* MT APIs warrant a response from the destination device, at which receiving the response would indicate that such device is still active, so the only concern is sleepy end nodes for which the message from the ZNP may timeout (NWK_INDIRECT_MSG_TIMEOUT) before the end device polls for data.

Regards,
Ryan
