4. Setup and Installation
Before proceeding with installation, ensure you have a compatible Z-Wave gateway and that the power supply to the circuit is disconnected.
4.1 Device Dimensions
The Shelly Wave i4 DC US LR is designed to be compact for easy integration. Its dimensions are approximately 42mm x 37mm.
Figure 2: Device dimensions. This image illustrates the compact size of the Shelly Wave i4 DC US LR, showing its length of 42mm and width of 37mm, held in a hand for scale.
4.2 Wiring Diagram and Connections
The device requires a 5-24V DC power supply. It features four digital inputs (SW1, SW2, SW3, SW4) for connecting switches or other input devices.
- +: Positive terminal for DC power supply (5-24V DC).
- -: Negative terminal for DC power supply.
- SW1, SW2, SW3, SW4: Digital input terminals for connecting switches. Connect one side of your switch to the input terminal (e.g., SW1) and the other side to the negative (-) terminal of the power supply.
Always consult a qualified electrician if you are unsure about wiring procedures.
4.3 Pairing with a Z-Wave Gateway
To integrate the Shelly Wave i4 DC US LR into your smart home system, it must be paired with a Z-Wave gateway (hub). The exact pairing process may vary depending on your gateway, but generally involves these steps:
- Power On: Connect the Shelly Wave i4 DC US LR to its 5-24V DC power supply.
- Gateway Inclusion Mode: Put your Z-Wave gateway into inclusion (pairing) mode. Refer to your gateway's manual for specific instructions.
- Activate Device Inclusion: Press the button connected to input SW1 four times quickly within 2 seconds. Alternatively, if no switch is connected, use the device's internal button (if available, consult specific product documentation for button location).
- Confirmation: Your gateway should detect and add the device. Once successfully paired, the device will appear in your gateway's interface.
A Z-Wave Gateway is required for the device to function within a smart home network.

5. Operating the Device
The Shelly Wave i4 DC US LR allows you to control various aspects of your smart home through its digital inputs. Each input can be configured to trigger different actions based on button presses.
5.1 Multi-Click Functionality
The device supports multiple actions per button press, offering flexible control:
- Single Click: Can be configured to turn lights on/off, toggle devices, or activate a specific scene.
- Long Click: Can be configured for actions like dimming lights, opening/closing blinds, or activating a different scene.
- Multiple Clicks: Up to 3 automation actions can be assigned per button, allowing for complex control with simple button sequences.
Figure 4: Advanced scene activation. This image demonstrates how multi-click functionality (1 click, 1 long click) can be used to control Z-Wave devices like turning lights on/off or dimming them, using a standard wall switch.
5.2 Scene Activation and Synchronized Actions
With the Wave i4 DC US LR, you can trigger complex scenes and synchronized actions across multiple Z-Wave devices. This allows for efficient control of your home environment with a single button press.
- Gateway-Controlled Scenes: Configure scenes within your Z-Wave gateway that are activated by specific button presses on the Wave i4 DC US LR.
- Direct Associations: The device supports 2 associations per button, enabling up to 8 actions to be triggered directly between Z-Wave devices without relying on the gateway for every command.
