So, I followed the process here as far as directory structure goes:
In the packages directory that is referenced inside configuration.yaml, I have a ping_zwave.yaml file with the following below. This ping_zwave.yaml is just your sensor to detect what nodes are dead. You could include unavailable, unknown in line 14, but I don’t run into those states ever, and pinging those nodes with those states will not resolve the problem anyway.
ping_zwave.yaml
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 dead_nodes = integration_entities('zwave_js') | select('match', 'sensor\..*node_status')| select('is_state', 'dead') | list -%}
{% set ns = namespace(buttons=[]) -%}
{% for e in dead_nodes -%}
{% set device_id = device_id(e) -%}
{% set button = device_entities(device_id) | select('match','button\..*_ping') | first -%}
{% set ns.buttons = ns.buttons + [button] -%}
{% endfor -%}
{{ ns.buttons }}
In the Automation GUI, I setup an automation like this:
If you’re into the YAML, here’s the backend of that GUI automation:
- id: '1669759724675'
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
