On raspbian it’s easy, you can put the DDF on (only 1 solution, the one you prefer):

  • /home/<DECONZUSER>/.local/share/dresden-elektronik/deCONZ/devices/sonoff this file will be prioritary and persistent on the official one
  • /usr/share/deCONZ/devices/sonoff here you need to edit the official one, there is already a DDF for this device called snzb-02-multisensor.json , at next deconz update the file will be replaced again.

After DDF replacement/modification, need to restart deconz, reset the device and re-include it.
