Easykon for KNX: compatible accessories and datapoints

Review the categories, command and status addresses, datapoints and values supported by Easykon for KNX to configure accessories.

This guide gathers the KNX accessory categories supported by Easykon for KNX and the datapoints required for command and status. Use the indicated values as a reference during mapping in the web interface.

Before configuring accessories

  • Work on the updated ETS project.
  • Check the command and status group addresses.
  • Check the datapoint type and length.
  • Test each function on the KNX bus before connecting external ecosystems.
  • Easykon for KNX is not Matter: it exposes accessories through supported integrations.

Limits and extra features

  • Availability in the external app depends on the category and functions supported by that platform.
  • Command and status must be distinct when required by the KNX project.
  • An incorrect datapoint can result in values that are not updated, inverted commands or unusable accessories.
  • After each change, save it, test it in the Easykon interface, and only then update the connected platforms.

If command and status are not correct

  • Check the group addresses in ETS.
  • Check the Data Point ID and length.
  • Check that the status telegram is actually sent on the bus.
  • Check for any scale conversions, for example 0–255 or percentages.
  • Remove and recreate the accessory only after ruling out errors in the KNX project.
