Notification if a Zigbee/Z-wave device drops out of the network

Hi all,

I was wondering if there is a way to have a notification if a device drops out of the network for any reason (low battery, malfunction, bad signal reception,…).

I have seen some things about polling but it is not yet clear for me.
Can it be done? What are the side effects?

Thanks a lot in advance.

This SmartApp can do that and a lot of additional things;

I haven’t used either the Simple Device Viewer mentioned above, nor the Device Monitor below:

Thanks a lot.
