There are not many config parameters that are associated with the v2 Bindings [contrary to the v1 bindings which have their own
*.cfg (and resulting
openhab.cfg is not used anymore in OH2.
Actually… I don’t know of any v2 Binding that has binding specific config info.
Most (if not all) of the parameters are directly configured on the Bridge -> Thing -> Channel (B/T/C) for the respective v2 Bindings. Each element (B/T/C) has its own parameters and they are described in the corresponding v2 Binding documentation.
Some v2 Bindings do not support textual configuration for B/T/C (I may be wrong here).
You can use PaperUI or
*.things files to set up these B/T/C configurations.
If PaperUI is used, these settings end up in the jsonDB. These are called “Managed” Things.
If flat text config files (*.things) are used, there is no secondary storage of their settings. OH2 reads the
*.things file from
$OPENHAB_CONF/things/ directly and loads it up in memory.
