Automation to take action on the zwave entity that fired zwave_js_value_notification

Configuration
1

So I am still learning the ins and outs of automation scripting and jninja2 code and I am hoping that someone can help with what I’m trying to do.

I have a bunch of zwave dimmer switches that support a “double tap” action. I have an entity group that contains these dimmers, and I want to make an automation that does the following:

  • triggers on the zwave_js_value_notification for a device in that entity group that matches {{ button_id == "001" and press_count == "KeyPressed2x" }}
  • sets the brightness to 100% with the light.turn_on service for the entity that triggered the automation

I know I can get the zwave device id from the value_notification event via trigger.event.data.device_id but I’m struggling to understand how to iterate through the entities in the entity group and how to associate the zwave device id with the entity it relates to.

I’m guessing there is something obvious I’m missing, hope someone can enlighten me.

You can easily accomplish this by using the EVENT trigger in your automation. The property key is unique to each button and this is how you can tell which button generated the event. The value raw key is unique to each event generated by the button. This is how you can tell what actions were performed on the button. On my device a double press has a value of 3 and a single press has a value of 0.

platform: event
event_type: zwave_js_value_notification
event_data:
  node_id: 12
  home_id: 3846008132
  command_class: 91
  property_key: "004"
  value_raw: 3

Thanks! I noticed that blueprint inputs have the ability to filter based on manufacturer and model. Is it possible to get these values for a given device_id in an automation?

I don’t think so. The only information displayed in the event viewer is the following.

event_type: zwave_js_value_notification
data:
  domain: zwave_js
  node_id: 12
  home_id: 3846008132
  endpoint: 0
  device_id: 08b20e6e1719d10de047a6d0b7d3707f
  command_class: 91
  command_class_name: Central Scene
  label: Scene 004
  property: scene
  property_name: scene
  property_key: "004"
  property_key_name: "004"
  value: KeyPressed
  value_raw: 0
origin: LOCAL

For anyone curious, I was able to figure this out with a tidy bit of blueprint code. With this blueprint I can select a list of light switch dimmer devices, and then if any of them have their “on” button/paddle pressed one time, it will turn that light on at 100% rather than what ever dim level it had previously been at. Works perfectly with HomeSeer dimmers, but other brands will likely need modification to the event-data variables (for example, Inovelli appears to use property_key “002” for up button instead of “001”…).

Here is the blueprint code:

blueprint:
  name: Lights to full brightness on single tap
  domain: automation
  input:
    zwave_dimmers:
      name: Set of ZWave Dimmers
      description: Select the Dimmer Switches to use
      selector:
        device:
          filter:
            - integration: zwave_js
              manufacturer: HomeSeer Technologies
          multiple: true

variables:
  device_ids: !input zwave_dimmers

trigger:
  #
  # Trigger on "on" button pressed zwave scene event from dimmer
  #
  - platform: event
    event_type: zwave_js_value_notification
    event_data:
      property: scene
      property_key: "001"
      value: KeyPressed
    id: up_button_pressed

#
# If the device that triggered the event is on the list, then set brightness to 100%
#
condition: "{{ trigger.event.data.device_id in device_ids }}"

action:
  - service: light.turn_on
    data:
      brightness_pct: 100
    target:
      device_id: "{{ trigger.event.data.device_id }}"
