Professional Home & Facility Automation
Wave Pro 2 enables sophisticated automation scenarios for lights, appliances, and electrical systems. Create custom schedules, timers, and scenes to synchronise your environment with daily routines or business needs. The potential-free outputs (dry contacts) support a wide range of AC devices and voltages, making it suitable for professional installations in new construction or retrofit projects. Control connected devices remotely via the Shelly Smart Control app or any certified Z-Wave gateway.
Z-Wave Smart Home Integration
Compatible with over 4,000 certified Z-Wave devices and gateways, the Wave Pro 2 seamlessly integrates into existing smart home ecosystems. The device supports Security 2 (S2) encryption, providing the highest level of IoT security available. Z-Wave mesh networking ensures reliable communication throughout your home or facility, with automatic routing and self-healing capabilities. Note: A Z-Wave gateway (smart hub) is required to configure and control this device.
Safe & Reliable Operation
The Wave Pro 2 includes overheating protection with internal temperature sensors that monitor the device every 100 milliseconds. If unsafe temperatures or rapid temperature rises are detected, the device automatically turns off and sends notifications. All Shelly Pro components are manufactured with flame-resistant materials that maintain structural integrity even when exposed to high heat levels. Most Wave devices operate at less than 0.3W power consumption, ensuring energy-efficient operation.
Installation & Compatibility
Compatible with both switches (default) and push-buttons for manual control. Each toggle of a connected switch changes the relay output state. The device supports configurable power failure states, automatic on/off timers, and NO/NC (normally open/normally closed) output configuration. Professional installation is recommended, especially for breaker box mounting. Ensure minimum 1cm spacing between multiple Shelly devices for proper airflow and heat dissipation.
