Product detailed description

📡 Shelly Wave i4 LR - Advanced Z-Wave Control with Extreme Long Range Capabilities

Add this unobtrusive yet incredibly powerful module directly behind your standard wall switch (using a regular 230V AC supply), wire it up, and instantly gain the magical ability to control any other Z-Wave devices in your home from this single location. You can trigger highly sophisticated smart scenes within your Smart Home ecosystem. The Shelly Wave i4 LR is supercharged with exclusive Z-Wave Long Range technology, which allows your button press to fly through the air directly to the main unit over a mind-blowing distance of up to 1 km.

This device from the Z-Wave 800 family does not contain any output (switching) relays. Instead, it serves exclusively as an intelligent command reader—it features 4 reading inputs to connect to physical wall buttons or switches. Once connected, the Wave i4 LR captures every button press and instantly reports it back to your Smart Home system. This enables the triggering of synchronized actions or complex automations with just a single push of a switch. Thanks to the long-range technology and near-zero power consumption, it ensures reliable performance not only in apartments but especially in massive warehouses, open-plan offices, and demanding outdoor installations.

The Shelly Wave i4 LR supports up to 4 independent inputs simultaneously, making it perfectly ideal for pairing with Shelly's own specialized 4-button wall switch. However, you can seamlessly hide it behind regular, classic 1-gang or 2-gang switches from any brand that are already mounted on the walls in your room.

Key Features and Functions of the Shelly Wave i4 LR

• 🔍 The Shelly Wave i4 LR is an input reading device (it contains no relays, does not disconnect circuits, and does not pass power to a bulb).
• 🖲️ Direct Local Control: Allows you to manually control other physical Z-Wave devices and relays (e.g., at the other end of the building) without needing the command to be processed by a central hub. The Z-Wave Associations function guarantees that your light will turn on even if your main smart hub is currently rebooting.
• 👆 Multi-Click Recognition: The module smoothly recognizes single clicks, double clicks, and long holds for each of the 4 button inputs. This allows you to define and trigger up to 16 different automation actions from a single spot (for example, a long hold could roll up the living room blinds).
• 📶 Supports Z-Wave Long Range (ZWLR): Maintains an unbeatably strong and fast radio connection over distances exceeding 1 km (direct line of sight on the matched frequency). In this mode, the device operates on a different frequency in a pure star-topology network, independent of signal repeaters (mesh).
• ⚡ Extremely Energy Efficient: Despite its massive range, it consumes less than 0.2 W of energy in standby mode.
• 🌐 Dual Radio Frequency Options: Based on your setup, the device can operate either on the 864.0 MHz channel (dedicated to the ZWLR network) or the common 868.4 MHz channel (as a standard Z-Wave Plus Mesh device).
• 🆕 Latest Chip Technology: Powered by the Z-Wave Series 800 platform.
• 🚀 Easy Setup with SmartStart: Just scan the device's QR code in the app, and you can pair it with your system in seconds (e.g., Home Assistant with an LR USB dongle, Hubitat, or even an older Fibaro hub in classic Z-Wave Plus mode).
• 🔒 Protection and Encryption: The device is designed to handle S2 Authenticated inclusion for the highest military-grade level of communication security.
• 🔄 Easy Maintenance: You can install the latest wireless firmware updates Over-The-Air (OTA) with the push of a button.

📝 Important Note: The module does not offer Wi-Fi connectivity. A certified Z-Wave gateway (Smart Hub) is absolutely required to operate it. To unlock the extraordinary 1-kilometer range, the ZWLR protocol must also be supported by the gateway itself. However, you can easily use the Wave i4 LR on a traditional Mesh network as well.
