ZWave JS multicast

Configuration Z-Wave
1

I was referencing this:

And am still trying to get my zwave to multicast to smartwings blinds to see if I can get them to come down at the exact same time.

This is my code:

actions:
  - action: zwave_js.multicast_set_value
    metadata: {}
    data:
      command_class: "106"
      property: targetValue
      value: 75
      device_id:
        - device_id_1
        - device_id_2
        - device_id_3

When I run this, I get a "Error: Unable to set value via multicast". In the example above, I am just trying to set the blinds to 75%. Attached is also a screenshot from one of the config pages in Zwave JS. I am a bit confused about the command class / property / value fields and what I need to put there.

Thanks for any help.

You're at least missing property_key: 13, or property_key_name: Outbound Bottom from the action data. Both are indicated in the screenshot with 57-106-0-targetValue-13 and Target value - Outbound bottom.

Also the fields can be found by downloading and examining the device diagnostic file.
