Automate ZwaveJS Ping Dead Nodes?

Configuration
49

I agree it can be confusing when people only post part of their configuration, especially since yaml is such a non-descriptive format. I’ll try to elucidate.

I put all of z-wave ping handling into a “package” file, that I load from my configuration.yaml.

In the configuration.yaml, near the top:

group: !include groups.yaml
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml

# added to the default includes to pull in packages
homeassistant:
  packages: !include_dir_named packages

And in the home-assistant directory (where the configuration.yaml file resides), create the directory “packages”. I put a file in the packages directory I called “zwave_ping.yaml”, with the following contents:

template:
  - sensor:
      - name: "Dead ZWave Devices"
        unique_id: dead_zwave_devices
        unit_of_measurement: entities
        state: >
          {% if state_attr('sensor.dead_zwave_devices','entity_id') != none %}
            {{ state_attr('sensor.dead_zwave_devices','entity_id') | count }}
          {% else %}
            {{ 0 }}
          {% endif %}
        attributes:
          entity_id: >
            {% set exclude_filter = ['sensor.700_series_based_controller_node_status'] %}
            {{
              expand(integration_entities('Z-Wave JS') )
              | rejectattr("entity_id", "in", exclude_filter)
              | selectattr("entity_id", "search", "node_status")
              | selectattr('state', 'in', 'dead, unavailable, unknown')
              | map(attribute="object_id")
              | map('regex_replace', find='(.*)_node_status', replace='button.\\1_ping', ignorecase=False)
              | list
            }}

automation:
  - id: ping_dead_zwave_devices
    alias: Ping Dead ZWave Devices
    description: ''
    trigger:
      - platform: state
        entity_id:
          - sensor.dead_zwave_devices
    condition:
      - condition: template
        value_template: >
          {{ int(states.sensor.dead_zwave_devices.state) > 0 }}
    action:
      - service: button.press
        target:
          entity_id: >
            {{ state_attr('sensor.dead_zwave_devices','entity_id') }}
    mode: single

Note the sensor can be added to your dashboard and will show a count of dead devices:

You can enable or disable the automation from the settings, but you cannot edit the automation using the visual editor. You can change that by putting the automation part in your automations.yaml file if you prefer.

If you disable the automation, you’ll see the count go up and down over time. Since enabling the automation, I’ve not had any persistent dead nodes.
