Shelly Wave Pro 3 (2025) LR – Professional Z-Wave relay with 3 channels, DIN rail mounting and Long Range technology

Shelly Wave Pro 3 (2025) LR is a professional Z-Wave relay with three independent channels, designed for DIN rail mounting in electrical panels, suitable for automating lighting and appliances in residential or commercial applications. Each channel can handle loads of up to 16A, with a total of 48A per device, offering flexibility for large-scale installations.

The device has potential-free (dry contact) outputs, which offers great flexibility in terms of supported voltages and applications, as it can control both low-voltage circuits and standard mains loads via external contactors.

Z-Wave Long Range technology maintains a stable connection over distances of up to 1km in a straight line, ideal for large buildings, industrial halls or installations where the electrical panel is far from the central hub. The Z-Wave 800 Series chipset ensures ultra-low consumption (below 0.3W), advanced S2 Authenticated security and quick setup via SmartStart.

Note: installation must be carried out by qualified personnel, in the electrical panel, and operation requires a compatible Z-Wave hub, and an LR receiver to enable Long Range mode.

Practical use cases

• It integrates into an existing Z-Wave network (Z-Wave hub, Home Assistant with a Z-Wave stick, or another compatible controller), extending home automation without adding a new ecosystem.
• Mounted on the DIN rail in the electrical panel, it controls lighting circuits or appliances via the potential-free contacts, benefiting from the extended coverage and stability of the Z-Wave protocol, ideal in buildings with thick walls.
• Each Wave device also works as a repeater in the Z-Wave mesh network, helping to extend the signal to other, more distant nodes.
• Note: Requires a compatible Z-Wave hub/controller (e.g. Home Assistant with a Z-Wave adapter) to be connected to the network and controlled from the app.

Technical specifications

For professional automation in large buildings or halls, with a stable connection over long distances from the hub, the Shelly Wave Pro 3 LR offers reliable control over three independent channels.
