KNX DPT and Control4 cross-check preview
The preview shows linked KNX data and Control4 devices so the installer can check channels, DPT assumptions and mappings before export.
Why DPT context matters
A group address alone does not explain whether it is an on/off command, a level feedback value, a stop command or a position percentage. DPT context helps determine how Control4 should use the value.
The AI Assistant uses this context together with names and ComObjects to build a device candidate that can be reviewed.
Lights and dimmers
Switch lighting is normally driven by on/off values, while dimmers need level values and feedback. The workflow should separate simple switches from dimmers and avoid assuming that every lighting address behaves the same.
DPT3 relative dimming is not part of the current automatic dimmer support, so it should be surfaced for review rather than silently treated as a complete dimmer.
Blinds and shades
Blinds often need movement commands, stop values, percentage positions and feedback. A Control4 blind can look correct but behave poorly if stop or feedback addresses are missing or inverted.
Review DPT assumptions before export
The goal is not to hide uncertainty. If DPTs, ComObjects or address names are incomplete, the review step should make that visible before the .codu export reaches Composer.
Official references checked
Technical claims on this page are kept close to official KNX, Control4, or manufacturer documentation.

FAQ
Is DPT enough to create a Control4 device?
No. DPT is important, but the workflow also needs names, ComObjects, group address families and room context.
Which DPTs matter most for supported devices?
The current workflow focuses on DPT-1 style on/off and stop values, DPT-5 style level or percentage values, and matching feedback where available.
What happens with unsupported DPT combinations?
They should be reviewed instead of being converted blindly into Control4 devices.
