Fibaro introduced a new config parameter #38 for the dimmer 2 with firmware version 3.5
Altough my device has 3.5 installed the parameter is not available in openhab.
I asume this is because is missing in the database. What is the easiest way to set this param? Will it be possible e.g. by directly using the rest api, patching the local device xml, …?
Adding the parameters to the database and waiting for the changes to show up in a snapshot (usually a day or two). My understanding is everything drives off of the database. If the parameters is not in the database it can’t be used in OH.
It’s there. You need to use a recent zwave binding version (snapshot or security):

If you already are on any of that version delete the thing and readd it again.
