Z-Wave Wake on Event End Node (WOEEN): Powering the Next Generation of Battery-Free Devices
Z-Wave introduces the Wake on Event End Node (WOEEN) role, enabling a new class of self-powered, energy-harvesting devices that operate entirely without batteries. These devices remain dormant until triggered, using harvested energy to communicate critical events, eliminating maintenance cycles, reducing electronic waste, and lowering total cost of ownership.
Built for Real-World Demands: Z-Wave Delivers with WOEEN
Z-Wave WOEEN is designed for real-world IoT and smart home environments where reliability and low maintenance are non-negotiable, spanning industrial machine health monitoring, smart agriculture sensing, building automation, and residential applications like leak detection sensors in attics, basements, and other hard-to-reach areas. These use cases rely on energy-harvesting devices that generate limited power and operate only when triggered, requiring ultra-efficient communication, long-range connectivity, and dependable event delivery.
Z-Wave Long Range (ZWLR) is purpose-built to meet these demands, enabling over one mile of coverage in a star topology with direct hub-to-device communication, eliminating the need for repeaters while improving reliability and latency. With optimized power management and support for thousands of nodes, ZWLR makes it practical to deploy scalable, battery-free, event-driven devices that operate predictably even with intermittent, harvested energy.
Bringing WOEEN Devices to Market, Faster
Z-Wave members can accelerate development of WOEEN-enabled devices by working with companies like WePower Technologies, which provide both energy-harvesting technology and design expertise to bring battery-free products to market. At the same time, devices like the WePower GemnsTM leak detector serve as real-world validation of the WOEEN device class, demonstrating how energy-harvesting sensors can reliably detect events and instantly transmit alerts. This accelerates time to market, reduces engineering risk, and enables scalable deployment of maintenance-free devices across residential and industrial applications.
The Z-Wave Alliance Advantage
The Z-Wave Alliance empowers members to shape the future of the standard, including innovations like WOEEN in the 2025B specification. Through collaboration, certification programs, and early access opportunities, members can accelerate development and ensure interoperability. Together, the ecosystem drives innovation while maintaining Z-Wave’s legacy of reliability and performance.
