Group addresses

The Group addresses tab on a project detail shows every KNX group address the project knows about, grouped into the familiar three-level main/middle/sub hierarchy. It is populated from the parsed ETS file and can be navigated, searched, and exported.

Columns

Column	Notes
Address	Three-level KNX address, e.g. 1/2/15.
Name	ETS-assigned group address name.
Datapoint type	E.g. DPT_Switch, DPT_Scaling, DPT_Temperature.
Main group	First-level label, usually a functional area.
Middle group	Second-level label, usually a sub-area.
Device	Linked device name, if the parser could match one.

Filtering

The search input supports:

• Free text — matches name, main group, and middle group substrings.
• Address prefix — type 1/ to filter to main group 1; type 1/2/ to filter to middle group 2 inside main group 1.
• DPT prefix — type DPT_Switch to see every binary group.

Exporting

Click Export → CSV in the top-right to download the currently filtered group address list as a CSV. The CSV uses the same column order as the table and quotes every field. It is suitable for importing into a spreadsheet for sign-off with a customer.

Excel-in-German users: the CSV is comma-separated with UTF-8 encoding (including a BOM), so it opens cleanly in "Daten → Aus Text/CSV".

Linking a group address to a function

Group addresses can be linked to functions — high-level groupings like "living room lighting" that span several GAs. The linking UI lives inside the device drawer on the Rooms & devices tab; see Rooms & devices for the workflow.

Functions are optional. A group address that isn't linked to any function shows a dash in the Device column.

Beta visibility

Functions are an experimental concept and the UI to create and manage them is behind a feature flag for most orgs. If you don't see the linking option in the device drawer, your org doesn't have the flag yet — drop us a note if you need it turned on.
