I have a Hue dimmer switch and would like to the use standard binding to read it’s button value. So far I have been using a network binding but given that the Hue binding also supports dimmer switches I’d liek to change to “standard”.
The documentation only states examples where I would register the bridge newly and in  the various devices. I do have, however, already some 50 devices registered as things on that bridge using automatic discovery and don’t want to delete them all and type everything into a file. I also can’t seem to be able to register the switch via paper UI (it only offers bulbs and smart plugs as types) so I’m looking for the right syntax for a new things file which would have only that switch and uses the existing bridge. The syntax for things suggest using
Thing <binding_id>:<type_id>:<thing_id> ,
so I tried
where “hue” is the name of the binding for the bridge, 0820 would be the device type according to the Hiue binding documentation and 17 the Id of the sensor (which I checked using via an HTTP request against the API) but that doesn’t seem to work, as ID 17 is already an existing bulb - apparently the information that there is also a sensor with ID 17 is not passed on …
What am I Missing? Must be something very simple, but as a beginner I’m not seeing it …
Thx and have a great day
