The Inspect tab in the Management page reads a device's communication tables directly from its memory and reconstructs which communication objects exist, what flags they have, and which group addresses are connected to them - without needing an ETS project. This is the most reliable way to understand an unknown or incorrectly documented device.
Prerequisites
- Connected to a KNX gateway (see Connect to a Gateway).
- The individual address of the device you want to inspect.
Steps
- Go to Management → Inspect tab.
- Enter the device's individual address in the input field.
- You can also reach this tab pre-filled from the Prog. Mode tab (tap Comm. Info on a card), from a Line Scan device card (tap Rebuild Communication), or from any device detail sheet.
- Tap Read. A progress bar shows which operation is in progress (address table, association table, communication objects).
- A session card appears for the device. The border colour indicates success (green) or failure (red).
Reading Full Device Info
The communication table read does not include detailed device info (manufacturer, firmware, etc.) by default. Tap Read Full Info on the session card to retrieve those details separately.
Viewing Session Details
Tap the session card to open its full details page. The top bar has a reload button to re-run the read, and a share button to export and share a PDF report for this session.
The details page has three tabs:
Associations
Lists all communication objects that have at least one group address connected:
| Column | Description |
|---|---|
| Number | Communication object index |
| Flags | R Read · W Write · C Communication · T Transmit · U Update · I Read-on-Init |
| Size | Object data size (1 bit, 1 byte, 2 bytes, etc.) |
| Group addresses | Addresses connected to this object |
Tap any group address to send a Read or Write command to it. Because the DPT is not known from memory alone, a raw hex/decimal value input is used instead of a DPT-aware UI.
Use Export CSV or Export TXT to export the associations list for this session.
Device Info
Shows the full device info card if Read Full Info was performed. Includes a Copy All button to copy all fields to the clipboard.
Addresses
A table of all group addresses found in the device's address table in memory (index, 3-level, 2-level, hex). Use Copy All or Export CSV to extract the full list.
Managing Sessions
Sessions are persistent - they survive app restarts and remain available until you clear them.
- Clear (above the card list) - removes all sessions
- Export (above the card list) - exports all sessions together as a single PDF
- Share (top bar of a session details page) - exports and shares just that one session as PDF
Notes
- A failed read (red border) usually means the device is not responding, is in an error state, or the address is wrong. Use Check from the Devices tab to verify the device is present on the bus first.
- If the device requires KNX Data Secure tool keys for device management operations, load the
.knxkeysfile in Discovery → Security tab before reading.
