Setting z-wave config value with fields in script

Configuration Z-Wave
1

I’m about to give up… I try to set up a script with fields so I can reuse it in different automations.

In my example i try to set a value for a z-wave dimmer (zooz) which is connected through z-wave js ui.

If i set the script up like this–it works (the value 99 turns the switch on––the value 0 turns it off):

alias: test - on dimmer
sequence:
  - device_id: 1edf04f10640f11e11f192b7be5d964e
    domain: zwave_js
    type: set_value
    command_class: 38
    property: targetValue
    value: 99

But if I try to add a field, it just does not work…

alias: test - on / off dimmer
sequence:
  - device_id: 1edf04f10640f11e11f192b7be5d964e
    domain: zwave_js
    type: set_value
    command_class: 38
    property: targetValue
    value: "{{ value }}"
fields:
  value:
    selector:
      number:
        min: 0
        max: 99
        step: 1
    name: value
    description: 0 = off / 99 = on
    required: true
description: ""

What am I missing? Thanks in advance!

I’m not sure that that device action supports the use of templates. You can confirm if that is true by using the integration action instead:

sequence:
  - action: zwave_js.set_value
    data:
      entity_id:
        - light.dining_room
      command_class: "38"
      property: targetValue
      value: "{{ value }}"

I personally would avoid using Device anything in automations/scripts anyways:

Also, why do you need to use the low-level Z-Wave action? HA provides you with a light entity to interact with, instead of requiring users to use protocol-specific functionality. A brightness of 0 will turn it off. You would only need to use set_value if the percentage value rounding doesn’t work for you (it scales 1-100% into 1-99 z-wave).

action: light.turn_on
target:
  entity_id: light.living_room
data:
  brightness_pct: 0
