SHELLY Wave i4 DC Switch

The SHELLY Wave i4 DC switch allows you to trigger a scene, activate an automation, or synchronize the operation of multiple devices with a single button press. This device provides convenient manual control for your smart home system and remains virtually invisible once installed behind a traditional wall switch. Supporting Z-Wave Long Range technology, energy-efficient operation, and featuring the latest-generation Z-Wave 800 chip, it is ideal for both small apartments and large-scale installations. It's a practical solution for those who want to maintain full control over their home automation without sacrificing traditional switches. Functioning as an input reader without relays, the device is designed to control other Z-Wave network devices. With a single button, you can manually activate or deactivate scenes, trigger complex automations, and perform synchronized actions involving multiple smart home devices. Its four inputs enable the use of multi-button switches, and the Multi-Click feature allows you to assign up to 16 different actions to various click combinations. Additionally, the device monitors input status, providing enhanced control over the entire system. The Shelly Wave i4 DC utilizes the latest Z-Wave 800 series and supports Z-Wave Long Range (ZWLR) technology, ensuring stable communication over distances exceeding 1 km in a straight line. You can operate in the 864 MHz band for Z-Wave Long Range or the 868.4 MHz band for the Z-Wave Plus standard, configuring it to suit your installation. Classic Z-Wave Plus offers an indoor range of up to 40 meters, and the device can act as a signal repeater. Z-Wave Long Range mode extends the indoor range to up to 80 meters and communicates directly with the gateway, making it perfect for larger homes and professional installations. Communication in the sub-GHz band ensures a stable connection, free from typical interference found in congested radio bands. Installation is simple with SmartStart technology, which adds the device to the Z-Wave network by scanning a QR code. The Shelly Wave i4 DC supports Security 2 (S2) authentication and AES-128 encryption, effectively securing network communication. Over-the-air (OTA) software updates allow the device to receive new features and security patches without removal. Its compact housing is designed for flush-mount installation behind a standard wall switch, making it completely invisible. With power consumption not exceeding 0.3 W, the Shelly Wave i4 DC operates efficiently even during continuous use. This product works with all certified Z-Wave Plus devices and gateways; however, Z-Wave Long Range technology requires a compatible gateway and ZWLR-enabled devices. **Specifications:** * **Model:** Wave i4 * **Power Supply:** 5–24 V DC * **Power Consumption:** < 0.3 W * **Overcurrent Protection:** None * **Power Measurement:** None * **Number of Inputs:** 4 * **Range (long-range network):** Up to 80 m indoors or up to 1000 m outdoors, Z-Wave® 864 MHz frequency band * **Mesh range:** Up to 40 m indoors, Z-Wave® 868.4 MHz frequency band * **Processor:** Z-Wave® S800 * **Maximum transmission power in frequency band(s):** < 25 mW * **Dimensions:** 37 x 42 x 16 ± 0.5 mm * **Weight:** 17 g * **Installation:** Flush-mount box * **Maximum torque for screw terminals:** 0.4 Nm / 3.5 lbin * **Wire cross-section:** 0.5 to 1.5 mm² / 20 to 16 AWG * **Stripped wire length:** 5 to 6 mm * **Housing material:** Plastic * **Color:** Yellow * **Ambient temperature:** -20°C to 40°C * **Humidity:** 30% to 70% relative humidity * **Maximum altitude above sea level:** 2000 m
