Bring Z-Wave to your SMLIGHT device. This addon adds Z-Wave 800 and Z-Wave Long Range support using Silicon Labs' latest EFR32ZG23 chip — the same platform used in premium Z-Wave controllers. It plugs directly into compatible SMLIGHT devices and lets you control Z-Wave smart home devices like locks, sensors, and thermostats alongside your existing Zigbee and Thread network. With Z-Wave Long Range, you get extended coverage that can reach outdoor sensors and detached buildings. The module includes hardware-level encryption (Secure Vault) for safe device pairing and communication.
Latest generation Z-Wave Plus V2 and Z-Wave Long Range for maximum compatibility and reach.
Z-Wave Long Range reaches outdoor sensors, garages, and detached buildings that standard Z-Wave can't.
Silicon Labs Secure Vault provides secure boot and encrypted communication out of the box.
Connects to compatible SMLIGHT devices via the built-in expansion slot — no soldering or adapters.
SMA antenna connector for even better range when needed.
Under 1 µA in deep sleep — negligible impact on your device's power consumption.
