Hi, can you explain how it works? Notify sensors that have a last_seen greater than 36 hours?
Would it be possible to store the number of reported devices somewhere? For instance in a helper?
All, Iāve been looking at this blueprint, but as Iām using NodeRed for most of my automations. I went into this direction and made an easy flow which you can connect to telegram or whatever. Iāve taken 4 hours to see if a device becomes unresponsive. This doesnāt take away the work that has been done in this blueprint and last_seen attribute that needs to be added as described in Offline detection for Z2M devices with last_seen - #28 by Kosy.
Hope this helps some folks out.

For people who want to use this blueprint as a sensor (so that you can show the list on a dashboard card), just put this in the template config file : (I choose 6 hours, you can change it)
`# Z2MQTT last seen
- trigger:
- platform: time_pattern
hours: /1
sensor: - name: z2mqtt last seen
unique_id: z2mqtt_last_seen
state: >
{% set result = namespace(sensors=[]) %}
{% for state in states.sensor | rejectattr(āattributes.device_classā, āundefinedā) | selectattr(āattributes.device_classā, ā==ā, ātimestampā) %}
{% if ālast_seenā in state.entity_id and (states(state.entity_id) == āunavailableā or ((as_timestamp(now()) - as_timestamp(states(state.entity_id))) > (6 * 60 * 60))) %}
{% set result.sensors = result.sensors + [state.name | regex_replace(find=ā last seenā, replace=āā) ~ ā (ā ~ relative_time(strptime(states(state.entity_id), ā%Y-%m-%dT%H:%M:%S%zā, āunavailableā)) ~ ā)ā] %}
{% endif %}
{% endfor %}
{{ result.sensors | join(ā\nā) }}`
- platform: time_pattern

Would it be possible / would it make sense to differenciate by device class, e.g.
- get an alert if a router is offline longer than one hour
- get an alert if a device if offline longer than six hours

I found this automation.
But itās no longer working - itās a convenient idea
Or the notification in the form - {{sensors}} will not go through
what do you mean by template config file? pls help a noob.
Works fine!
When creating the automation based on the BP, youāll have to add an action, a notification for example. Key is to add {{sensors}} in order to get the sensor names
service: notify.persistent_notification
data:
title: Sensors last_seen exceeded 4hrs
message: |
Sensors to check:
{{sensors}}
Message Timestamp: {{ now().strftime("%d-%m-%Y %H:%M.%S") }}
Automation: [Devices, Z2M - last_seen exceeds 4hrs]

@Mr_Groch
Hello,
Just a quick post to say thank you.
I was looking for something that can help to monitor my Z2M devices and your blueprint is perfectly doing the job 
@peter_kawa : You service example allow to do a quick test, thanks for sharing.
Thanks !

Will be good if the blue print could be updated and support Excluded Sensors via Labels.
@Mr_Groch any chance you can add this?

Hi Peter.
Can you help me with not being told which devices are offline in z2m? I just get this message as you can see in the picture. I have used the same yaml code as you, but with my own mobile phone
Hi J,
I donāt know what goes wrong here.
Hereās my yaml and a screenshot, I hope it helps!
alias: Devices, z2m - 18:00 chk last_seen exceeded 24h
description: ""
use_blueprint:
path: Mr-Groch/offline-notification-for-sensors-with-last_seen.yaml
input:
hours: 24
actions:
- service: notify.mobile_app_s9_pe_hass_vm
metadata: {}
data:
title: Zigbee device(s) silent
message: |
Sensors last_seen exceeded 24 hours: {{sensors}}
@ {{ now().strftime("%d-%m-%Y %H:%M.%S") }}
[Devices, z2m - 18:00 chk last_seen exceeded 24h]
- service: notify.persistent_notification
data:
title: Zigbee device(s) silent
message: |

@ {{ now().strftime("%d-%m-%Y %H:%M.%S") }}
[Devices, z2m - 18:00 chk last_seen exceeded 24h]
time: "18:00:00"
Itās weird, it wonāt send a message about the devices that are offline, it just sends the message with the text written in it. It is as if there is no connection from HA to z2m regarding last seen status. It is switched on in z2m.
all I get is
This template listens for the following state changed events:
- Domain: sensor
what have I missed
Hi, just wanted to say thank you !
Regards.
Hi, Iāve added this to my Z2M configuration file so āLast seenā sensor is enabled by default, but after restarting z2m multiple times, it still doesnāt show.
Any ideas? Thanks
device_options:
homeassistant:
last_seen:
enabled_by_default: true
Have you also done :
advanced:
last_seen: ISO_8601_local
Yeh, but I switched it back to ISO_8601, should it be set to local?
Edit: I got it partially working, it only applies to newly paired devices. I had to manually enable last_seen for existing ones.
Hi!
I would really like to use that blueprint, but ever get this error:
Error rendering variables: ValueError: Template error: as_timestamp got invalid input 'unknown' when rendering template '{% set result = namespace(sensors=[]) %} {% for state in states.sensor | rejectattr('attributes.device_class', 'undefined') | selectattr('attributes.device_class', '==', 'timestamp') %} {% if 'last_seen' in state.entity_id and not state.entity_id in exclude.entity_id and (states(state.entity_id) == 'unavailable' or ((as_timestamp(now()) - as_timestamp(states(state.entity_id))) > ((hours | int) * 60 * 60))) %} {% set result.sensors = result.sensors + [state.name | regex_replace(find=' last seen', replace='') ~ ' (' ~ relative_time(strptime(states(state.entity_id), '%Y-%m-%dT%H:%M:%S%z', 'unavailable')) ~ ')'] %} {% endif %} {% endfor %} {{ result.sensors | join(', ') }}' but no default was specified
I know itās something with defaults, but could not find the right place.
Please help - Thanks
Chances are you installed it and type run, but donāt have all the required inputs.
May I suggest checking the inputs against those required then triggering the blueprint the way it was intended.
Note: I donāt know this blueprint personally, but I am getting this from the error you posted. Please forgive me if Iām wrong.)
