Offline detection for Z2M devices with last_seen

Thanks for your reply. All inputs except of 3 are ok - but that’s the reason for that blueprint. I’m sure there is a new requirement for code with unknown input. The code needs a default set like this “default=0” - but i can’t find the right place. The error message directed to “as_timestamp”. Any thoughts about that? Thanks

Ok - really strange! I changed nothing, but after a few days it just works.

Thanks anyway!

Many thanks for the code.

I have slightly adapted the code by adding two functions: “Minutes not seen” and “Included Sensors”.

Regards!

Hello, I am out of ideas, please (and sorry if I post to wrong site). When I use this bueprint, I recieve this message: “Last seen (unawailable) Last seen (unawailable)”. Alld evices are awailable, so where does this mesage come from ? why it is generated?

Offline detection for Z2M devices with LQI

This is great, thanks. Would it be possible to add Notification Channels for Android devices?

I am using the following code for the template sensor with the following changes:

  • default added (the 0 in as_timestamp(states(state.entity_id),0)) to fix the no default was specified error message
  • correct check to remove Last seen in the name (for my sensors it’s Last seen in stead of last seen)
  • added the domain of the entity_id
{% 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 (states(state.entity_id) == 'unavailable' or ((as_timestamp(now()) - as_timestamp(states(state.entity_id),0)) > ((24 | int) * 60 * 60))) %}
        {% set result.sensors = result.sensors + [state.name | regex_replace(find=' Last seen', replace='') ~ ' (' ~config_entry_attr(config_entry_id(state.entity_id), 'domain') ~ ' | ' ~ relative_time(strptime(states(state.entity_id), '%Y-%m-%dT%H:%M:%S%z', 'unavailable')) ~ ')'] %}
    {% endif %}
{% endfor %}
{{ result.sensors | join('\n') | truncate(254, True) }}

Which results in the following list for entities which are in this example all unavailable:

Light 1 (zwave_js | unavailable)
Switch 2 (mqtt | unavailable)
Sensor 3 (mqtt | unavailable)

This can be used in the blueprint as well.
