The Z-Wave Alliance, the organization responsible for advancing the open-source Z-Wave standard across smart home and smart building ecosystems, has marked a significant milestone in the adoption of Z-Wave Long Range (ZWLR). The consortium recently announced that 125 Z-Wave Long Range–certified devices are now commercially available, highlighting growing industry support for the latest evolution of the protocol. While Z-Wave is not part of the Matter smart home standard, ZWLR introduces a set of capabilities that position it as a compelling alternative for large-scale residential and commercial deployments.
One of the defining advantages of Z-Wave Long Range is its extended communication capability. ZWLR devices can connect directly to a compatible hub over distances of up to 1.5 miles under line-of-sight conditions, a substantial increase over traditional Z-Wave implementations. This extended range is enabled by a star network topology, where each device communicates directly with the hub rather than relaying signals through neighboring nodes. The result is reduced latency, more predictable network behavior, and simplified deployment and troubleshooting.
Scalability is another major improvement introduced with ZWLR. A single Z-Wave Long Range hub can support up to 4,000 devices on a star network, a dramatic increase compared to the 232-node limitation of earlier Z-Wave mesh networks. This expansion significantly broadens the range of potential use cases, making ZWLR particularly attractive for commercial buildings, multi-dwelling units, and very large smart homes that exceed the practical limits of previous-generation Z-Wave technology.
Energy efficiency is also a core benefit of Z-Wave Long Range. ZWLR devices dynamically adjust their transmit power based on their distance from the hub, reducing unnecessary energy use when full transmission strength is not required. This adaptive behavior makes the technology especially well suited for battery-powered products such as sensors, door locks, and security devices. According to the Z-Wave Alliance, certain sensor-class devices can achieve battery lifespans of up to 10 years when powered by coin-cell batteries, reducing maintenance requirements and long-term operating costs.
Despite its architectural changes, Z-Wave Long Range maintains backward compatibility with earlier generations of Z-Wave devices. ZWLR and classic Z-Wave products can coexist on the same network and interoperate in both star and mesh configurations, allowing users and installers to mix new and existing hardware without abandoning previous investments. However, there are important technical distinctions. To fully realize ZWLR’s extended range and scalability benefits, a hub must be equipped with a ZWLR-capable chip. In addition, ZWLR devices do not route traffic for classic Z-Wave mesh devices, and traditional Z-Wave products do not participate in ZWLR star communications. While classic Z-Wave devices can function on a star network and ZWLR devices can operate within a mesh network, non-ZWLR hardware does not gain access to the long-range advantages of the newer standard. Furthermore, when ZWLR devices are added to a mesh network, the system remains subject to the older 232-device limit, which, while sufficient for most homes, constrains larger installations.
Adoption strategies among device manufacturers continue to vary. Ring, for example, has transitioned many of its newer sensors and smart home products to Amazon’s Sidewalk network, moving away from Z-Wave for new designs. However, the company has not abandoned its existing Z-Wave-based devices, which remain supported as legacy components within Ring Alarm and Ring Alarm Pro systems. Other major players, including ADT, continue to invest in Z-Wave and ZWLR. ADT’s Smart Home Security System introduced in late 2025 integrates support for both standards and maintains compatibility with a wide range of third-party Z-Wave devices, including advanced smart locks.
At the silicon level, Silicon Labs continues to play a central role in the Z-Wave ecosystem. After acquiring Zensys, the original creator of Z-Wave, and open-sourcing the technology in 2019, the company has focused on enabling broader developer flexibility. At CES, Silicon Labs demonstrated how device makers can design products that support both Z-Wave Long Range and Amazon Sidewalk using a single hardware solution, the ZG28 system-on-a-chip platform. This approach is intended to reduce development complexity and allow manufacturers to target multiple smart home ecosystems with a unified design.
A growing number of products already illustrate the expanding ZWLR ecosystem. These include smart home hubs, security panels, sensors, lighting controls, adapters, sirens, and smart locks designed to take advantage of long-range communication and improved scalability. Devices such as touchscreen-based security panels for professional installers, extended-range smoke detectors for European markets, modular smart locks with interchangeable radio modules, ZWLR adapters for Home Assistant deployments, outdoor-capable door and window sensors, discreet long-range smart locks, and customizable siren and chime units collectively demonstrate the breadth of applications now supported by Z-Wave Long Range.
With increasing device availability, improved scalability, and continued backward compatibility, Z-Wave Long Range is steadily positioning itself as a mature and flexible connectivity option for next-generation smart home and smart building deployments, particularly in environments where range, reliability, and device density are critical requirements.
