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:
