KNX, DALI-2 and EnOcean certification
KNX Association, the DALI Alliance and the EnOcean Alliance each run a private certification programme that gives a product the right to use a trademark and a listing in a product database. None of them is a regulatory approval: the EU file for the same product still runs through RED for radio variants, the LVD and EMC Directive for wired ones, and ecodesign Regulation (EU) 2019/2020 for LED drivers. This page describes each programme from the alliance documents themselves (who may certify, who tests, what the logo covers), then lists the EU references that apply in October 2026, with the version and the Decision that cites it.
Where the three alliances sit in the regulatory stack
Section titled “Where the three alliances sit in the regulatory stack”KNX, DALI and EnOcean define frame formats, addressing, device profiles and commissioning, so devices from different manufacturers work together. Their certificates say nothing about radio spectrum use, electrical safety or EMC, which are set by EU law.
| Layer | Governed by | What a KNX, DALI or EnOcean product typically meets |
|---|---|---|
| Market placing in the EU | Directives 2014/53/EU, 2014/35/EU, 2014/30/EU | CE marking, EU declaration of conformity |
| Radio (KNX RF, EnOcean, DALI+ or gateways) | RED 2014/53/EU, ETSI harmonised standards in Decision (EU) 2022/2191 | EN 300 220-2 (sub-GHz), EN 300 328 (2.4 GHz), EN 301 489-3 |

KNX certification
Section titled “KNX certification”Standards behind the KNX protocol
Section titled “Standards behind the KNX protocol”The protocol is published as the ISO/IEC 14543-3 series (parts 3-1 to 3-7, first editions published in 2006 and 2007) and in Europe as the EN 50090 series for Home and Building Electronic Systems (HBES). Two security documents were added later: EN 50090-3-4:2017 (secure application layer, corrigendum 2018), and EN ISO 22510, which KNX Association says was published at the end of November 2019 and covers KNXnet/IP including KNX IP Secure.
| Variant | Medium | Typical use |
|---|---|---|
| KNX TP | Twisted pair bus, 9600 bit/s | Wall-mounted sensors and actuators in fixed installations |
| KNX RF | 868 MHz SRD band | Retrofit, areas without bus cabling |
| KNX IP | Ethernet or Wi-Fi, KNXnet/IP tunnelling and routing | Backbone between TP lines, IT integration |
| KNX PL | Power line | Installations without a dedicated bus cable |
Who may certify
Section titled “Who may certify”The KNX certification procedure presented by the KNX Certification Manager on 30 June 2025 sets the conditions:
- The manufacturer must be a KNX shareholder or a KNX Royalty-per-Unit licensee. An Interested Party member is "not allowed to certify any products".
- ISO 9001 is not required for an OEM product registration. For a main registration it is required when the company developed its own physical layer or stack; if the physical layer or stack is already certified, the company may use an ISO 9001 subcontractor instead.
- The manufacturer requests a unique 2-byte manufacturer code, used by ETS to check that the application program and the device come from the same originator.
Registration, then 6 months to test
Section titled “Registration, then 6 months to test”| Step | What the KNX procedure says |
|---|---|
| 1. Membership | Shareholder or Royalty-per-Unit licensee |
| 2. Manufacturer code | Requested online in MyKNX |
| 3. Manufacturer Tool project | Output file knxei, uploaded to MyKNX with the hardware, product and application program data sheets |
| 4. Registration | KNX returns a knxrcd file and an invoice for the registration fees; the manufacturer can then distribute knxprod files and upload them for the ETS online catalogue |
| 5. Market entry | "Manufacturer can already sell the product with KNX logo for a quick market entrance" |
| 6. Within 6 months | Interworking test report of the application program, carried out by a KNX accredited test lab with the EITT test tool |
The interworking and functionality tests check that the product behaves as declared and that its data point types conform to the KNX specifications, plus behaviour on initialisation, reset and power failure, the hop count used in telegrams and telegram rate limitation for cyclical functions. Hardware must meet KNX Volume 4/1 (EMC to 63044-5, electrical safety to 63044-3, environmental conditions to 50491-2), and those tests may be performed in house or at third-party test labs.
For KNX RF, the radio part needs RED in parallel: the KNX registration does not assess Article 3(2) spectrum use.
KNX Secure
Section titled “KNX Secure”KNX Association describes KNX Secure as two mechanisms: KNX Data Secure, which authenticates and encrypts telegrams on the KNX media, and KNX IP Secure, which encrypts KNXnet/IP communication between installations. Both use AES-128 in CCM mode. KNX Secure is not a condition for registration. It does not replace the EU cybersecurity texts either: an internet-connected KNX RF product falls under the RED Article 3(3)(d)(e)(f) delegated act applicable since 1 August 2025 (EN 18031-1 cited with restrictions by Decision (EU) 2025/138), and products with digital elements fall under the Cyber Resilience Act, whose reporting obligations apply from 11 September 2026 and full application from 11 December 2027.
DALI-2 and D4i certification
Section titled “DALI-2 and D4i certification”The DALI Alliance programme
Section titled “The DALI Alliance programme”The DALI Alliance (legal name Digital Illumination Interface Alliance, DiiA) runs DALI-2 and D4i certification. Its certification overview states:
- Only DiiA members can certify, and only Regular or Associate members, with an annual fee of EUR 15,000 or EUR 5,000 respectively. Each certified product uses one certification credit, bought in advance, as a one-time fee; certification stays valid as long as the company remains a member.
- Who tests: "Member companies execute the required tests for each product", using test sequences downloaded from the member website on approved test equipment; "Members can also use the services of accredited DALI test houses".
- Verification: the member submits the results online and the DALI Alliance verifies them. No certificate or test report is issued: the listing in the public product database is the proof of certification.
DALI itself is the IEC 62386 series: each subnet supports 64 control gear (for example LED drivers) and 64 control devices (for example sensors), each control gear holds 16 scenes. The general parts were revised by the IEC on 16 November 2022: IEC 62386-101:2022 (edition 3.0) and IEC 62386-102:2022 (edition 3.0) replace the 2014 editions with Amendment 1:2018, and IEC 62386-103:2022 is edition 2.0. Which edition a product must use is set by the DALI Alliance "Allowed Parts of IEC 62386" document (updated June 2026, members only).
Parts available for certification (status page, October 2026)
Section titled “Parts available for certification (status page, October 2026)”| Part | Scope | DALI-2 | D4i |

Timeline
Section titled “Timeline”| Date | Event (DALI Alliance timeline) |
|---|---|
| August 2017 | Phase 1: Parts 101, 102, 103 and 207, so bus power supplies, LED drivers and single-master application controllers |
| August 2018 | Multi-master application controllers and integrated bus power supplies added |
| May 2019 | Input devices: Parts 301 to 304 |
| November/December 2019 | D4i test sequences: Parts 250 to 253 and Part 150 |
| February 2020 | Part 209 tunable white |

| September 2021 | Parts 202, 205, 206 and 209 colour types xy and RGBWAF |
| April 2022 | DALI version-1 registration closed |
| June 2026 | "Allowed Parts of IEC 62386" document updated |
D4i is the DALI Alliance programme for intra-luminaire DALI. An LED driver is D4i certified when it implements Part 250 and all of Parts 251 to 253 and meets the "D4i Certification and Trademark Use" requirements; testing extends DALI-2 testing on ProbitLab2. Control devices qualify through Part 351. Luminaires are not certified: the D4i trademark may be used on a luminaire that meets the trademark document. Parts 250 to 253 are now published IEC standards (the DiiA specifications were withdrawn).
Wireless: DALI+ and gateways are two different routes
Section titled “Wireless: DALI+ and gateways are two different routes”- DALI+ carries DALI commands over wireless or IP networks, based on IEC 62386-104 and the DiiA "Part 104 Changes and Additions" specification. The DALI Alliance states that the first DALI+ certification programme uses Thread.
- Wireless to DALI gateways translate between a non-DALI ecosystem and wired DALI devices. Part 341 covers Bluetooth NLC and Part 342 covers Zigbee.
A gateway with a 2.4 GHz radio (for example BLE for Bluetooth NLC) therefore has three files: DALI-2 (Part 341 or 342), the ecosystem qualification (see Bluetooth SIG qualification), and RED with EN 300 328 and EN 301 489-3.
EnOcean Alliance certification
Section titled “EnOcean Alliance certification”EnOcean radio standards
Section titled “EnOcean radio standards”The EnOcean air interface is standardised as ISO/IEC 14543-3-10:2020 (amplitude modulated short-packet protocol, AMWSP, edition 2.0 of 30 March 2020, replacing the 2012 edition) and ISO/IEC 14543-3-11:2016 (frequency modulated short-packet protocol, FMWSP, edition 1.0 of 19 February 2016). The EnOcean Alliance certification handbook refers to both as "ISO / IEC 14543-3-1X" and has separate air interface specifications for ASK and FSK. Its product page lists EnOcean GmbH radio modules at 868 MHz, 902 MHz, 921 MHz and 928 MHz.
In the EU, an 868 MHz EnOcean product is a short range device under RED. Its Article 3(2) reference is EN 300 220-2: V3.3.1 since 11 December 2025, with V3.1.1 removed from the list on 11 June 2027 (Decision (EU) 2025/2499).
Who may certify
Section titled “Who may certify”The Certification Handbook V 1.4 (released October 2025) states that the manufacturer must be a Participant or Promoter member, and defines the product manufacturer as the member responsible for the product on the market, "same as a white label product seller". Products designed and introduced to the market before 31 December 2017 count as legacy products and do not require certification.
Certification levels
Section titled “Certification levels”| Level | Required certification | Typical test route |
|---|---|---|
| Platform-Certified | Air interface (ASK and FSK specifications) | Radio chip and module makers only |
| Self-Certified | Air interface, self-declaration of correct profile use | Air interface usually from the module supplier, profiles self-tested with EnOcean Alliance tools |
| Self-Certified for IoT | As above with enhanced security, plus a QR code on product or packaging | As above |
| Alliance-Verified | Air interface, radio performance, communication profiles, energy harvesting | Full test set |
| Alliance-Verified for IoT | As above with enhanced security, plus QR code | Full test set |
Certification can be run "by the device manufacturer" or "by accredited test laboratories". A product built on an already certified platform can refer to the platform certificate under the handbook rules (it still receives its own certification number). The EnOcean Alliance "does not specify any security certification tests": secure telegrams that decode correctly according to the Security of EnOcean Radio Networks specification are enough. For a Self-Certified product, the product page says approval and an e-mailed certificate follow "after latest 2 weeks".
Cross-protocol comparison
Section titled “Cross-protocol comparison”| Dimension | KNX | DALI-2 / D4i | EnOcean |
|---|---|---|---|
| Base standard | ISO/IEC 14543-3, EN 50090 | IEC 62386 | ISO/IEC 14543-3-10, -11 |
| Who may certify | Shareholders, Royalty-per-Unit licensees | Regular or Associate members | Participant or Promoter members |
| Who tests | Hardware in house or third party; interworking at a KNX accredited lab | Member or accredited DALI test house | Manufacturer or accredited lab, depending on level |
| Logo before tests | Yes, after registration, report due within 6 months | No, after verification | No, after approval |
| Proof of certification | KNX certificate and ETS online catalogue | Listing in the product database (no certificate issued) | Certificate and certified product database |
| Security option | KNX Data Secure, KNX IP Secure | Depends on transport (DALI+ with Thread adds application-layer security) | Security of EnOcean Radio Networks specification |

Regulation (EU) 2019/2020 defines "data-connection parts" as parts receiving or transmitting "wired or wireless data signals", so a DALI LED driver awaiting a command falls in the networked standby definition for a connected separate control gear.
Claims the texts contradict
Section titled “Claims the texts contradict”| Common claim (including the previous version of this page) | What the texts say |
|---|---|
| "DALI-2 Bluetooth mesh is certified under IEC 62386-104" | The DALI Alliance routes Part 104 to DALI+ (first programme: Thread). Bluetooth NLC is a gateway under DiiA Part 341. |
| "DALI-2 tests are run on a DiiA Test Bench by accredited labs" | Members run the downloadable test sequences on approved equipment themselves, or use an accredited test house; the DALI Alliance verifies the results. |
| "DiiA issues a DALI-2 certificate" | No certificate or test report is issued; the product database listing is the proof. |
| "DALI supports 64 short addresses per bus" | 64 control gear and 64 control devices per subnet. |
| "EnOcean has a free Adopter tier that can certify" | Certification requires Participant or Promoter membership. |
| "EnOcean is ISO/IEC 14543-3-10, -11 and -12" | The handbook refers to ISO/IEC 14543-3-1X with ASK and FSK specifications; the current editions are 3-10:2020 and 3-11:2016. |
| "The KNX logo may only appear once tests pass" | After registration the product can be sold with the KNX logo; the interworking report is due within 6 months. |
| "KNX conformance testing is all done at a KNX lab" | Hardware tests may be in house or third party; the interworking test of the application program is done at a KNX accredited lab. |
| "EN 60950 for electrical safety" | Not a reference for these products: luminaires and LED drivers use the EN 60598 and EN 61347 series, HBES devices EN IEC 63044-3. |
| "ETSI EN 300 220 is the radio standard" (no version) | EN 300 220-2 V3.3.1 is cited since 11 December 2025 and becomes the only cited version on 11 June 2027. |
| "A DALI-2 driver has no energy rule of its own" | As a separate control gear it meets the 2019/2020 standby and networked standby limits. |
Common pitfalls in a KNX, DALI-2 or EnOcean file
Section titled “Common pitfalls in a KNX, DALI-2 or EnOcean file”- Treating the alliance mark as the regulatory passport. The marks are private. A device listed by the DALI Alliance that fails EN IEC 55015 emissions cannot carry CE.
- Joining at the wrong membership level. KNX Interested Party members, DALI Alliance Community members and EnOcean Alliance members below Participant cannot certify products.
- Missing the KNX 6-month window. The KNX logo is usable after registration, but the interworking report from an accredited lab must follow within 6 months.
- Picking the wrong IEC 62386 edition. The DALI Alliance "Allowed Parts" document sets which edition and amendment each Part must follow.
- Calling a gateway "wireless DALI". The DALI Alliance distinguishes DALI+ (DALI commands carried over wireless) from gateways (translation to Bluetooth or Zigbee).
- Keeping EN 300 220-2 V3.1.1 after 11 June 2027. Products placed on the market after that date need to be assessed against V3.3.1, or through a notified body.
- Forgetting the luminaire. DALI-2 and D4i cover the control interface; see EN 60598 and IEC 61000-4-3 for the luminaire safety and immunity work.
Practical mapping
Section titled “Practical mapping”| Product type | Alliance programme | EU route |
|---|---|---|
| HVAC room controller, fan-coil actuator | KNX (TP or RF) | LVD and EMC (EN IEC 63044-3, EN 50491-5-x); RED if KNX RF |
| LED driver for an office luminaire | DALI-2 Parts 101, 102, 207; D4i if 250 to 253 | LVD (EN 61347-1, EN 61347-2-13), EMC (EN IEC 55015, EN 61547), ecodesign 2019/2020 |
| Battery-free switch or occupancy sensor | EnOcean, Self-Certified or Alliance-Verified | RED (EN 300 220-2, EN 301 489-3) |
| Bluetooth NLC to DALI gateway | DALI-2 Part 341, Bluetooth qualification | RED (EN 300 328, EN 301 489-3), plus the RED cybersecurity act if internet-connected |
| DALI+ device on Thread | DALI+ (Part 104) | RED for the 2.4 GHz radio |

Frequently asked questions
- Does a KNX, DALI-2 or EnOcean certificate replace CE marking?
- No. The three programmes are private trademark and interoperability schemes run by KNX Association, the DALI Alliance (legal name Digital Illumination Interface Alliance, DiiA) and the EnOcean Alliance. CE marking still rests on the Low Voltage Directive 2014/35/EU and the EMC Directive 2014/30/EU for wired products, or on the Radio Equipment Directive 2014/53/EU for KNX RF, EnOcean and other radio products, plus ecodesign Regulation (EU) 2019/2020 for LED drivers and light sources. See RED procedure for the radio side.
- Who can certify a KNX product, and when can the KNX logo be used?
- According to the KNX certification procedure presented by KNX Association on 30 June 2025, the manufacturer must be a KNX shareholder or a KNX Royalty-per-Unit licensee; Interested Party members cannot certify. After registration the product may already be sold with the KNX logo, and the manufacturer then has 6 months to deliver an interworking test report from a KNX accredited test lab. Hardware tests (EMC, electrical safety, environmental conditions) may be run in house or at third-party labs.
- What is the difference between DALI version-1 and DALI-2?
- DALI version-1 compliance was a self-declaration without verification of results, and covered control gear only. DALI-2 certification, opened in August 2017 for Parts 101, 102, 103 and 207, involves verification of the test results by the DALI Alliance and covers control devices such as sensors and application controllers. Registration of new DALI version-1 products has ended (DALI Alliance page updated April 2022); registered products stay in the database.
- Does DALI-2 certification require an accredited test house?
- No. The DALI Alliance states that member companies execute the required tests themselves with the downloadable test sequences on approved test equipment, or use an accredited DALI test house. The member then submits the results with one pre-purchased certification credit per product, and the DALI Alliance verifies them. Certification is open only to Regular or Associate members.
- Is DALI-2 wireless the same as Bluetooth mesh under IEC 62386-104?
- No. IEC 62386-104:2019 covers wireless and alternative wired transport of DALI, and the DALI Alliance routes it to the DALI+ programme, whose first certification target is Thread. Bluetooth and Zigbee are handled by separate DiiA specifications for wireless to DALI gateways: Part 341 (Bluetooth NLC Gateway) and Part 342 (Zigbee Gateway), both shown as available for DALI-2 certification.
- Which EnOcean Alliance members can certify, and do they need a lab?
- The EnOcean Alliance Certification Handbook V 1.4 states that the manufacturer must be a Participant or Promoter member. The Self-Certified levels need the air interface tests (usually from the module supplier) and a self-declaration of correct profile use; the Alliance-Verified levels add radio performance and energy harvesting tests. Certification can be done by the manufacturer or by accredited test laboratories.
- Does a DALI-2 driver certificate cover the luminaire?
- No. DALI-2 tests the control interface. The luminaire is assessed against the LVD standards cited in Decision (EU) 2023/2723, such as EN IEC 60598-1:2021 with A11:2022 and EN 62471:2008, and the driver against EN 61347-1:2015 and EN 61347-2-13:2014. EMC uses EN IEC 55015:2019 with A11:2020 for emissions. The D4i trademark may be used on luminaires, but the DALI Alliance does not certify luminaires. See EN 60598.
- Which EN 300 220-2 version applies to an 868 MHz KNX RF or EnOcean product?
- Decision (EU) 2025/2499 of 9 December 2025 added EN 300 220-2 V3.3.1 to the RED list from its publication on 11 December 2025, and deletes the row for V3.1.1 with effect from 11 June 2027. Until that date either version gives presumption of conformity for Article 3(2); after it, only V3.3.1 does.
