Interoperability between all Z-Wave products is the cornerstone of the brand.
In order to make this brand promise to developers, customers, and consumers, there is a straight-forward certification program in place. All Z-Wave products must be certified before commercial launch. When the certification requirements have been met, products can feature the Z-Wave interoperability logo badges.
There are 2 components to Z-Wave certification. Technical certification is managed through Silicon Labs utilizing an independent 3rd party test house. Market Certification is managed through the Z-Wave Alliance.
Official badges for Z-Wave and Z-Wave Plus certified products.
The Certification Process is Simple:
- Purchase a development kit from one of the distributors listed here and gain access to the Z-Wave technical site where all the specifications for certification are spelled out.
- Join the Z-Wave Alliance as a full member, as this is a requirement for market certification. Consider this step early in your development process, in order to take advantage of the many benefits in the Alliance that can speed your time to market. The marketing guidelines for certification are here.
- Request access to the web-based Z-Wave Plus Certification Portal and start a device submission to help identify all of the certification requirements.
a) Select one of the independent test houses to perform the testing.
b) Use the integrated Wiki to see the test specifications for your device.
- Download the Certification Test Tool (CTT) tool from the Z-Wave Technical website (ZTS) and use it during product development to test and verify your Z-Wave implementation.
- After ensuring a compliant product, finalize and submit your form on the portal. A case number is automatically assigned as soon as it is submitted. You can start working with the test house as soon as your submission has been reviewed and approved.
- Start your Market Certification on the Z-Wave Alliance’s website as soon as you have a case number.
- Device certifications are issued after the device has passed the technical tests AND the Market Certification has been approved by the alliance.
- After approval, launch your product into the interoperable Z-Wave ecosystem, which enjoys over 70% market share in the smart home.
Z-Wave Certification Program
April 1st was the last day that a new Z-Wave Plus device could be submitted based on SDKs v6.51.xx or v6.61.xx.
All new Z-Wave Plus devices submitted on or after April 2, 2017 MUST be based on SDK v6.71.xx or newer and implement S2.
Certification of devices to Z-Wave standards is required as part of the SDK agreement and every device must pass a series of stringent tests to assure that it is compliant.
The number of companies developing Z-Wave products along with the variety and applications for those products is constantly increasing. Since the foundation for continuous growth of Z-Wave in the world marketplace is interoperability, the importance of compliance to Z-Wave standards cannot be overstated.
All devices and software utilizing Z-Wave technology must be certified. An SDK licensee can build up to 500 prototypes of a device during the development process but these cannot be sold. If they are distributed for testing & evaluation they MUST be marked as “non-certified samples” and “not for resale”.
All developers MUST have a Manufacturer ID assigned to their company. Requests for new IDs must be sent here and include the following:
- Company name as it should be listed in our database
- Company address
- Complete contact information for the primary certification contact
- Public or Private
- Public means that it can be published within the Z-Wave developers’ community
- Private means that it will be kept confidential until the developer’s first device is certified.
Certification of devices to Z-Wave standards prior to distribution and/or sale is mandatory. This is covered in the agreements that must be accepted and signed as a prerequisite to the purchase of a Z-Wave SDK.
There are two separate certification programs for end devices; Classic Z-Wave for 300 series devices and Z-Wave Plus for 500 series devices. A third program, QFN Certification, is required for custom implementation of a Z-Wave ASIC.
- Classic and Z-Wave Plus devices are tested by our independent test partners; BuLogics in Philadelphia, Pennsylvania, USA and Pepper-One in Zwickau, Germany. The role of the test partner is to confirm the test results provided by the developer. Contact information is provided in the Classic certification form and on the Z-Wave Plus certification portal.
- Custom ASIC implementations for QFN certifications are tested by Sigma Designs’ team in Singapore.
Regardless of whether it is Classic Z-Wave or Z-Wave Plus, certification is also a prerequisite for the use of the Z-Wave logo or name. The Z-Wave or Z-Wave Plus logo on a product or package assures consumers, dealers, integrators and service providers that the products will reliably perform with any other Z-Wave certified device designed for the same region.
A detailed description of the certification program is described in this document:
Z-Wave Certification Support
Technical questions regarding the Z-Wave protocol or Command Class implementation can be answered by your Silicon Labs' Field Application Engineer.
Contact Support for questions regarding certification requirements and/or processes.
QFN Certification Program
QFN Certification, is required for custom implementation of a Z-Wave ASIC. Contact Sales to learn more about this certification.
Design review and testing is performed by Silicon Labs' team. QFN certifications only cover the custom ASIC implementation and end device(s) utilizing these must also be certified to the appropriate Classic or Z-Wave Plus standards.
Certification Maintenance and Fees
Certification Maintenance: It is the OEM’s/developer’s responsibility to maintain their certifications and keep them current. Changes to certified devices typically require re-certification however; in some situations a one-page Compliance Statement may be all that is needed. Please refer to Section 3 of the INS10638 Certification Overview for details.
Important Notice: Changing the Z-Wave ASIC or module in a certified device requires that the device undergo a full new certification.
Certification Fees: Fees for testing end devices are paid to the independent test partner for their services in testing and verifying compliance to the specifications and standards. Fees are listed in the INS12578 Certification Fee Schedule.
Compliance Test Tool (CTT)
The Z-Wave Compliance Test Tool (CTT) is provided by Silicon Labs to licensees of the Z-Wave Software Development Kit (SDK). The CTT is designed to ensure that developers have a tool to assist in performing the self-certification tests required for verification that Command Classes (CCs) have been implemented correctly.
Use of the CTT does not guarantee certification, but it is a significant aid to the manufacturers’ self-certification process.
