Z-Wave Raw configuration parameter

Tutorials

Z-Wave Raw configuration parameters in Homey (Pro) allow you to send specific commands directly to your Z-Wave devices, bypassing the standard user interface. This can be particularly useful for advanced users who want to fine-tune their devices or access features not available through the default settings.

In my case the blinds attached to my Fibaro RollerShutter 3 did reset their slats position after moving to the end points/limit. #annoying
Unfortunately the app would offer no obvious setting to adjust what is described in the manual:
https://manuals.fibaro.com/roller-shutter-3/#post-9786

For Venetian blinds (parameter 151 set to 2) the parameter determines slats positioning in various situations.
The parameter is irrelevant for other modes.

Available settings:
0 – slats return to previously set position only in case of the main controller operation.
1 – slats return to previously set position in case of the main controller operation, momentary switch operation, or when the limit switch is reached.
2 – slats return to previously set position in case of the main controller operation, momentary switch operation, when the limit switch is reached or after receiving the Switch Multilevel Stop control frame

Default setting: 1

Parameter size: 1 [bytes]

How to Use Z-Wave Raw Configuration Parameters in Homey

  1. Optional for sending raw commands in your flows: Enable Power User Mode:
  • Go to the Homey app.
  • Navigate to More > Settings > Experiments.
  1. Accessing Raw Configuration Parameters:
  • In the Homey app, go to the device you want to configure.
  • Navigate to Advanced Settings.
  • Look for the Raw Configuration Parameters field. This is where you will enter your parameters.
  1. Formatting the Parameters:
  • The parameters need to be entered in the format [id, size, value; id, size, value; ...].
  • ID: The parameter number you want to configure.
  • Size: The size of the parameter (usually 1, 2, or 4 bytes).
  • Value: The value you want to set for the parameter.
  1. Example:
  • If you want to change the slats behavior on a Fibaro RollerShutter, you might enter 153,1,0 in the field. This means parameter 153, size 1 byte, value 0 (which means “off”).
  1. Sending the Parameters:
  • After entering the parameters, save the settings.
  • The parameters will be sent to the device, and you should see the changes take effect immediately (for battery-powered devices, you might need to wake them up first).

What I learned

Consult Device Manuals: Always refer to the device’s engineering sheet or manual to understand the available parameters and their values.

In my case I also discovered the possibility to adjust the slats moving speed: 152,4,85; 153,1,0

Hope this helps.
