Shelly Wave i4 – Z-Wave 4-Input Scene Controller (AC Powered)
Overview
Shelly Wave i4 is a Z-Wave input controller designed to convert up to four physical switches or push-buttons into smart triggers for scenes, automations, and device control. It does not switch loads directly and contains no relays; instead, it reports input actions to your Z-Wave network, enabling flexible manual control of other devices from standard wall switches.
Key Features
• 4 digital inputs for switches or push-buttons
• Input reader only — no relays and no direct load switching
• Supports multi-action input (short, long, and double press)
• Up to 12 actions or scenes configurable (3 per input)
• Z-Wave associations for direct device-to-device control (up to 2 per input)
• Extremely low standby power consumption (< 0.2 W)
• Z-Wave 800 Series (S800) chipset
• SmartStart for fast, secure inclusion
• OTA firmware updates
• Security 2 Authenticated (S2)
• Acts as a Z-Wave repeater to extend mesh coverage
