I found it not obvious enough on how to get notified when battery Zigbee / Zwave devices, or smartplugs, have fallen off the network…
So, I made this blueprint that will report when any of your Zigbee/Zwave(Battery) devices falls off the network. Works with ZHA & Z2M. Works for any SmartPlugs / SmartSwitches also.
You can easily get a notification to your phone, or alerts spoken to your Alexa/Google speaker etc, when any device has gone offline.
This is an upgrade over my previous version - the main difference is this reports just the device that has fallen offline, whereas my previous version would report all sensors that were unreachable. This was unneccesarily verbose when one device had multiple sensors… Also cleaned up the code to make it more readable.
Use {{offline_devices}} to get a list of all offline devices.
Below is an example on how you woud notify your phone with a list of offline devices.
service: notify.myphone
data:
message: "The following devices are unavailable: {{ offline_devices }}"

#Originally Based on the work of Sybx @ https://community.home-assistant.io/t/low-battery-level-detection-notification-for-all-battery-sensors/258664
#Note: This has been upgraded to report only the device that is offline, not multiple individual sensors within one device

So that is “normal operation” in this house.
