-## Enabling UPnP
-
-The add-on, by default, disables the native UPnP functionality of deCONZ.
-This is because the add-on uses an alternative discovery mechanism that allows
-for an improved integration experience.
-
-Nevertheless, the add-on allows you to enable UPnP again, in case you want
-deCONZ to be discovered by other applications (that are not Home Assistant).
-
-Add the `upnp` add-on option, and set it to `true` to enable UPnP:
-
-```json
-{
-  "device": "/dev/ttyUSB0",
-  "vnc_password": "",
-  "upnp": true
-}
-```
