xxter
xxter has a built-in KNX bus connection, so it works as the KNXSENSE bus recorder without a separate KNX/IP gateway.

How the recorder works.
The KNXSENSE recorder is installed on the device as separate software. It has no effect on anything else the device does. Logic, visualisation, interfaces and scripts keep running as normal.
The recorder reads the bus and never writes to it. It opens the connection outbound from the site, so no open ports, VPN or static IP address are needed. It also works behind a shared carrier IP address.
Recording requires xxter to be powered on continuously and the site to have an internet connection.

How telegrams reach the recording.
xxter is connected directly to the KNX bus, so it sees the telegram traffic on its own line and everything the line couplers route onto that line from the other lines.
KNXSENSE compares the addresses it sees against your ETS project and tells you straight away which lines and devices are in the recording and which are missing.
KNX bus monitoring in your browser.
Every telegram xxter sees on the bus is recorded around the clock, to the millisecond, on our secure servers — even when you are not on site.
Telegram-level history reaches 400 days back on a rolling window. You can browse it in your browser, on any device, without the ETS software.
Remote ETS access through the device, no VPN.
The connection is ETS tunnelling that runs through KNXSENSE. You open it in the user interface, and ETS then connects to the site’s KNX bus.
Recording reserves one ETS tunnel slot and holds on to it. The remaining slots stay free for ETS, so remote access works alongside recording.
Remote access is included in the KNXSENSE monthly fee. No separate portal, licence, port forwarding or VPN is needed.
Setting up xxter as your recorder.
KNXSENSE’s setup assistant walks you through the right settings step by step.
The whole setup takes only a few minutes.

Setup is a one-off job. When updates to the recorder are released, they are installed on the device automatically. Updating requires no action from you and no visit to the site.
