1. Membership

From not-member to KNX Member

Membership types available from the beginning:

• Interested Party (certification is not possible).
• Licensee
• Shareholder

Available membership upgrades:

• Interested Party > Licensee.
• Interested Party > Shareholder.
• Licensee > Shareholder.

Membership comparison

(*) Membership Fee invoices are issued in March (Fix Membership Fee for Interested Party and Shareholders, and Minimum Membership Fee for Licensees).

(**) When 1% of the sales figures exceeds the already paid annual fee, the rest is invoiced to the licensee at the end of the year.

2. Development

How to approach KNX development (options)

1. Acquiring OEM products ('Derived' from existing 'Certified' products).
2. Using existing Certified System Components (KNX Stack + Physical Layer).
3. Full development (own solution using specific certified components, such as a TP-UART, or developing from scratch).

Comparison

There is an inverse correlation between the development/certification effort and the financial investment in components.

3. Certification/Validation

Certification

Procedure described in Volume 5 of the KNX specifications. Various types:

• Application Product (i.e. Dimmer actuator).
• Basic Components (i.e. TP1 power supply).
• System Components (i.e. BCU).
• System Devices (i.e. USB).

Validation

Various types:

• ETS Apps.
• Device Configuration Apps.

Certification Process

From unregistered to certified:

1. Register new Hardware/Software (KNX Association).
2. Obtain REGISTERED database.
3. Test the device at an accredited KNX test lab.
4. Submit the positive test result to KNX Association (done by KNX test lab).
5. Obtain CERTIFIED database.

Validation Process

From unregistered to validated:

1. Request ETS App developer status.
2. Submit App (upload required file).
3. Manual validation (KNX Association).
4. Publication in MyKNX.
