[APP] Fibaro - Your home is your castle (by Athom)

With raw configuration.

There are several ways to do this:

  • Developer → Tools → Z-Wave (with the long code as described in the linked post)
  • Advanced settings of the Dimmer 2 → Raw Configuration
  • Flow, in the “Then…” section → add card “System/Z-Wave” → Send unprocessed command (or similar)

Afaik, it’s not possible to change parameter via raw configuration if the device is secured included.
