Shelly Wave i4 DC ZWave LR 800 4 Input Module

The Shelly Wave i4 DC is a compact Z-Wave smart input module designed to give you flexible, reliable control over your smart home automation system. It allows you to connect up to four physical switches or push-buttons and use them to trigger scenes, automations, or control other Z-Wave devices within your network. Unlike relay-based devices, the Wave i4 DC is a dedicated input controller, meaning it does not switch electrical loads directly. Instead, it acts as a smart trigger for your connected Z-Wave ecosystem. Key Features 4 independent input channels for switches or push-buttons Z-Wave 800 Series technology for improved performance and reliability Supports scene activation and automation triggers Multi-click support (up to 12 different actions per input) Ultra-low power consumption (< 0.3 W) Works with certified Z-Wave gateways and hubs Secure communication with Z-Wave S2 encryption SmartStart for fast and easy pairing Compact design for installation behind wall switches Firmware updates over-the-air (OTA) support Technical Specifications – Shelly Wave i4 DC Device type: Z-Wave input controller (no relay output) Inputs: 4 independent digital input channels Input type: Dry contact / low-voltage switch or push-button Power supply: 5–24 V DC Power consumption: < 0.3 W (ultra-low power) Wireless protocol: Z-Wave (Smart Home mesh network) Z-Wave generation: 800 Series Security: Z-Wave S2 encrypted communication SmartStart support: Yes (fast inclusion into Z-Wave networks) Scene control: Supports multi-click input actions (up to 12 actions per input, hub dependent) Automation use: Scene triggering, device control, and Z-Wave associations (via hub) Firmware updates: Over-the-air (OTA) updates supported Operating temperature: -20°C to 40°C Installation type: In-wall mounting (behind switches/buttons) Compatibility: Works with certified Z-Wave gateways and controllers Network type: Z-Wave mesh network (supports extended range via routing devices) Enclosure: Compact form factor for standard electrical wall boxes Electrical requirement: Low-voltage DC only (no AC input support) Function limitation: Does not switch or power electrical loads directly
