Overview
As smart home technology expands beyond the walls of the home, homeowners and integrators are seeking secure, long-range solutions for outdoor spaces. Z-Wave Long Range (LR), powered by Silicon Labs’ industry-leading wireless SoCs and modules, delivers mile-long coverage, multi-year battery life, and proven reliability for connected outdoor applications — from smart lighting and irrigation to perimeter security and environmental monitoring.
Why Z-Wave Long Range for Outdoor IoT?
Z-Wave LR was designed to address beyond-the-home smart automation challenges, offering:
Full Property Coverage
1+ mile wireless range star topology
(4× longer than classic Z-Wave)
Low Maintenance
Up to 10-year battery life for outdoor sensors
Massive Scalability
Supports up to 4,000 nodes on a single network
Rock-Solid Reliability
Sub-GHz operation for better wall and foliage penetration
Interoperable &
Future-Proof
Full backwards. compatibility with
Z-Wave Mesh
Secure Connectivity
Z-Wave S2 encryption and SmartStart pairing
Key Applications for Connected Outdoor Living
From perimeter security to garden automation, Z-Wave LR enables manufacturers to design reliable, long-range wireless products that go beyond the walls of the home without requiring repeaters or complex infrastructure.
Key outdoor IoT applications include smart security (gate locks, motion sensors, floodlights) and automated lighting (pathway, decorative, and security lighting). These products help consumers extend protection and control across the entire property while giving manufacturers a way to tap into high-value, differentiated categories that benefit from robust, low-power wireless performance.
Environmental sensing and automation also present strong opportunities. By combining irrigation control with climate monitoring, manufacturers can deliver smarter solutions for gardens, pools, and yards—such as weather-aware sprinklers, soil moisture sensors, and air quality monitors. Z-Wave LR enables these devices to operate reliably over long distances and with minimal maintenance, opening the door to new outdoor use cases and recurring customer value.

EFR32ZG28 SoCs
EFR32ZG28 SoCs
The EFR32ZG28 SoC is an ideal dual band Sub-GHz + 2.4 GHz BLE SoC solution for “Internet of Things”. The ZG28 is an ideal platform for Z-Wave applications that require more Flash, RAM and GPIO than the ZG23 device. The ZG28 is pin compatible with the ZG23 in the 6x6 QFN48 package. Z-Wave addresses applications for smart homes, security, lighting, and hospitality. The ZG28 can also support other protocols including Wi-SUN, Amazon Sidewalk, and Wireless M-BUS.
The single die, multi-core solution, provides industry leading security, low power consumption with fast wakeup times, and integrated power amplifiers to enable the next level of secure connectivity for IoT devices. The Large memory footprint and the integration of AI/ML hardware accelerator is ideal for Smart End Nodes.



ZGM230S Modules
ZGM230S Modules
The ZGM230S is a system-in-package (SiP) module for Z-Wave connectivity and networking built for the performance, security, and energy demands of the Smart Home. Based on the EFR32ZG23 SoC, it delivers robust RF performance, long-range, industry leading security features, low-current consumption, a rich set of MCU peripherals, all in a 6.5 x 6.5 mm package. The ZGM230S is a complete solution supported by powerful and fully upgradeable software, advanced development and debugging tools, and documentation that will simplify and minimize the development cycle, certification process, and deployment of your end product, helping to accelerate its time-to-market significantly.





EFR32ZG23 SoCs
EFR32ZG23 SoCs
Z-Wave 800 Modem SoCs are designed to meet the demands of the future smart home, hospitality, and MDU IoT products, where range, performance, and device security are key. While the EFR32ZG23 devices are the ideal solution for Z-Wave, they can also support other protocols including Wi-SUN, Amazon Sidewalk, and Wireless M-BUS IoT applications. The single die, multi-core solution, provides industry leading security, low power consumption with fast wakeup times, and an integrated power amplifier to enable the next generation of secure connectivity for IoT devices.
