Innovation & Adoption – Zigbee momentum in 2021

Innovation & Adoption – Zigbee momentum in 2021 sets groundwork for growth in 2022

Zigbee is a full-stack, low-power, secure solution for smart devices. This market proven technology connects smart homes and commercial buildings around the globe. Celebrating 17 years since inception, landing on Mars, and hitting the 4,000+ certification milestone, 2021 continued to mark growth and momentum for Zigbee. 

Zigbee in 2021

Launched in December 2004, Zigbee celebrated its 17th birthday as a wireless mesh standard. Zigbee’s longevity is a testament to the maturity, evolution, and market readiness that can only be achieved with years of real-world deployment and adoption.  

With over a half-billion Zigbee chipsets sold and nearly four billion expected to ship by 2023, Zigbee continues to be one of the world’s most popular Internet of Things (IoT) standards used by millions of devices and customers and backed by key players in the industry through the Connectivity Standards Alliance.

In 2021, the technology continued to evolve with the announcement of new features including Zigbee Direct, a new Zigbee Sub-GHz solution and collaboration with the DALI Alliance. Last year demonstrated continued success and milestones for Zigbee with the release of the new Zigbee Unified Test Harness (ZUTH), which enables more efficient and effective design and pre-testing against Alliance standards.

Steady Certification Uptrend

The Zigbee Certified programs ensure quality, interoperable Zigbee products are available for product developers, ecosystem vendors, service providers, and their customers. Zigbee Certification means a product has completed thorough, standardized testing ensuring that products which carry the Zigbee Certified mark will interoperate. 

Despite the continued challenges of Covid and the international silicon chip shortage, 2021 was another record breaking year for Zigbee. The technology reached a new milestone with more than 4,000+ Zigbee Certified products and platforms available to the market and 1,000 Zigbee 3.0 devices certified. This upward trend in certifications continues from 2020 and is a reflection of a steady market demand, continued deployment, and widespread industry adoption of the low-power wireless technology. This year more than 530+ new Zigbee devices were certified with devices ranging from lighting, switches, in-home displays and smart meters. 

This continued certification growth is the result of collaboration from hundreds of global manufacturers and developers who have worked to expand the interoperable universe for all users. The top 10 Zigbee product certifiers in 2021 include: Adeo Services, Hangzhou Sky-Lighting Co., IKEA of Sweden, Landis+Gyr AG, Leedarson IoT Technology Inc., LEGRAND, Lidl Stiftung & Co., Schneider Electric, Silicon Labs, Tuya Global Inc.

Zigbee Goes Extraterrestrial

Zigbee is now on Mars! Zigbee had another memorable moment in March 2021 being used in NASA’s Mars mission as the communication radio between the Ingenuity drone and Perseverance rover. Robust, reliable, and low-power Zigbee is not only a great choice for residential and commercial applications on Earth, but is highly suitable for missions to Mars!

New Tools – Zigbee Unified Test Harness (ZUTH) and PICS Tool Launch

CSA launched the free Zigbee Unified Test Harness (ZUTH) and PICS Tool. ZUTH combines the functionality of the previous Zigbee test tool and Green Power Test Tool to streamline and further simplify the certification process. ZUTH can be used to pretest the latest versions of Zigbee 3.0, base device behavior (BDB) and Green Power specifications before attending members’ preferred Authorized Test Laboratory (ATL) where ZUTH will be used as the official tool. ZUTH issued 320+ licenses in 2021 highlighting the continued development and certification of new Zigbee products and platforms. 

Additionally, the new online PICS tool allows members to complete their PICS electronically and generate XML files which can be directly submitted to the Certification Team or used with ZUTH for test selection. This new tool in addition to ZUTH simplifies the testing process and streamlines the certification process for Alliance members.

Active Development and Member Investment Continues

Zigbee Working groups have been tirelessly working on new features and enhancements, including Zigbee Direct and a new SubGHz solution, slated to release in 2022. Participation in Zigbee development continued to grow last year with 185+ member company participants and over 1,340 individual participants working to create new features and further advance the Zigbee technology. 

As we look to 2022, CSA reached out to our members to learn about their Zigbee success and some of the latest Zigbee-enabled products to hit the market, making the lives of consumers more connected and convenient.
