As detailed here, deCONZ is moving to a new config model where device definitions are held in DDF json files rather than merged into a core code. This allows much faster, and user-enabled addition of new device support.
To provide this capability to HA addon users, the add-on should support mapping the container DDF directory
~/.local/share/dresden-elektronik/deCONZ/devices/ to a HA core config directory (i.e. /config/deconz/devices)
Many devices will soon use DDF Files because since the last version of deCONZ (in integration v6.11.1), DDF file are enabled by default at deCONZ startup. I use them for example for my LiXee Zlinky_TIC module for example see here
FYI a DDF File library has been opened into the deCONZ Forum here
Thank you !
