I use zha instead of z2m so I don’t know how much of this will work for you but this is my approach for sending notifications to all of my switches. I have two different scripts to make this work:
alias: Send Inovelli Notification
sequence:
- service: zha.issue_zigbee_cluster_command
data_template:
cluster_type: in
ieee: "{{ieee_id}}"
endpoint_id: 1
cluster_id: 64561
command: 1
command_type: server
params: "{{command_args}}"
mode: parallel
icon: mdi:bell
max: 100
This script takes the ieee_id of the switch and the args for the event. Those are supplied by the script below.
alias: Trigger Switch Notification
sequence:
- alias: Iterate through switch notifications
repeat:
count: "{{ ieee_ids | count }}"
sequence:
- variables:
ieee_id: "{{ ieee_ids[repeat.index - 1] }}"
- service: script.turn_on
data_template:
variables:
command_args:
led_effect: 1
led_color: 1
led_level: 99
led_duration: 255
ieee_id: "{{ieee_id}}"
target:
entity_id: script.send_inovelli_notification
variables:
ieee_ids: |-
{% set result = namespace(ids=[]) %}
{% for state in states.light %}
{% if device_attr(state.entity_id, 'model') == 'VZM31-SN' %}
{% set result.ids = result.ids + [(device_attr(state.entity_id, 'identifiers')|list).0.1] %}
{% endif %}
{% endfor %}{{ result.ids }}
mode: single
icon: mdi:bell
The script works by finding the ieee_ids of all lights that match the blues model number. It then iterates through all of the ieee_ids and sends cluster commands to each individual switch.
You can calculate the values for command args as follows:
led_effect: Invollei Quirks.led_color: Invollei Switch Toolbox.led_level: 0~99.led_duration: 0~255 (255 is infinite).
You can also technically combine this into one script, but zha sometime fails to send a command to a single switch. If it’s one script that causes the whole thing to fail. By breaking it out into another script only that single switch notification fails instead.
