#### Group Address Notation
```text
<config>="[<dpt>:][<]<mainGA>[[+[<]<listeningGA>][+[<]<listeningGA>..]]"
<config>="[<dpt>:][<>]<mainGA>[[+[<]<listeningGA>][+[<]<listeningGA>..]]"
```
where parts in brackets `[]` denote optional information.
**Each configuration parameter has a `mainGA` where commands are written to and optionally several `listeningGA`s.**
`mainGA` also listens to incoming packets, unless prefixed with a `>` character.
This is recommended if you have a dedicated status group address which is added as `listeningGA`.
The optional `<` sign tells whether the group address of the datapoint accepts read requests on the KNX bus (it does, if the sign is there).
All group addresses marked with `<` are read by openHAB during startup.
The group addresses marked with `<` are read by openHAB during startup.
Future versions might support reading from one GA only.
With `*-control` channels, the state is not owned by any device on the KNX bus, therefore no read requests will be sent by the binding, i.e. `<` signs will be ignored for them.
Each configuration parameter has a `mainGA` where commands are written to and optionally several `listeningGA`s.
The `dpt` element is optional. If omitted, the corresponding default value will be used (see the channel descriptions above).
The element `dpt` is highly recommended and may change to a mandatory element in future versions.
If omitted, the corresponding default value will be used (see the channel descriptions above).
