Import the ETS Project
Load the exported ETS project so group addresses arrive with their names, locations and datapoint types already attached.
Protocol Support
KNX Integration
Listen to KNX group telegrams over KNX IP, map group addresses from your ETS project, and control rooms from one place.
- Standard
- ISO/IEC 14543-3, EN 50090
- Medium
- Twisted pair (TP), KNX IP, KNX RF
- Topology
- Line and area bus, linked by couplers
- Data Model
- Group addresses (for example 1/2/5) carrying typed datapoints (DPT)
What KNX Is
KNX is the open standard for room and building control: lighting, blinds, heating and presence. Devices share state by sending telegrams to group addresses. A group address has no meaning on its own, so the ETS project that designed the installation is the real source of truth for names and data types.

How IoTServa Connects KNX
KNX IP Tunnelling and Routing
Connect through a KNX IP interface or router, and listen to the telegrams that move on the bus.
Read and Command
Read switch, dim, blind and temperature values, and send commands back to the same group addresses.
Scenes and Schedules
Run time-based and rule-based actions across rooms without adding load to the KNX bus itself.
Typical Jobs
- Hotel and residential room status
- Lighting and blind schedules across a building
- Energy reporting from KNX meters
- Bridging KNX into a wider BMS or dashboard
Plan for These
Without the ETS project you only see numbers. Keep the exported project with the site records.
KNX IP interfaces allow a limited number of simultaneous tunnels. Plan which one IoTServa uses.
Do not flood the bus. Prefer listening to reading, and write sparingly.
KNX Questions
Can IoTServa read KNX without the ETS project?
It can, but you will only see raw group addresses and numbers. The ETS export is what turns them into named, typed points.
Does IoTServa work over KNX IP?
Yes. It connects through a KNX IP interface or router using tunnelling or routing.
