Open box Shelly Wave Pro Dimmer 2PM – light dimming module with 2 outputs (Z-Wave)

What does "open box" mean?

Open-box products are returned products with opened or damaged packaging, but fully checked from a technical point of view and completely functional. They come with the same warranty as new products.

Shelly Wave Pro Dimmer 2PM is a professional DIN rail-mountable Z-Wave dimmer, designed for integrators and installers equipping electrical panels with advanced lighting control. The device offers two independent dimming channels, with built-in power monitoring for each controlled channel.

DIN rail mounting makes it suitable for professional electrical panels, where space and wiring organisation are essential, unlike compact modules mounted directly in the wall box. It integrates into any existing Z-Wave network via a compatible gateway or hub, enabling remote control and complex lighting automations.

It is recommended for large-scale commercial or residential projects, where centralised lighting control from a single electrical panel is preferred over installing each dimmer individually behind the switch. Power monitoring also makes it possible to track the energy consumption of the controlled lighting circuits.

Note: this device requires a Z-Wave hub or gateway for full operation and must be installed by qualified personnel, as it works directly with mains voltage in the electrical panel.

Practical use cases

• Installed on the lighting circuit of a living room, it lets you adjust light intensity directly from the app or by voice command, for the right atmosphere at every moment of the day.
• Integrated into an automation system, it can gradually lower the brightness in the evening, simulating an artificial sunset that helps you relax before bed.
• Combined with a motion sensor, it turns on the hallway lights at reduced intensity at night, without disturbing anyone with overly bright light.
• Lets you create different scenes (reading, relaxing, entertaining) for the same bulb or chandelier, with no need to install a classic wall dimmer.

Technical specifications

For professional lighting control mounted directly in the electrical panel, Shelly Wave Pro Dimmer 2PM offers reliability and consumption monitoring in the Z-Wave ecosystem.
