Open box Pack of 2 relays Shelly 2PM Gen3

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.

This pack contains 2 units of the Shelly 2PM Gen3, a WiFi relay with two independent channels and power monitoring on each channel, suitable for controlling two separate circuits, such as roller shutters or two lighting zones. Each unit in the pack works independently, with its own WiFi address, and can be configured separately in the Shelly app, which makes it convenient for installers and integrators equipping several circuits or rooms in the same project.

Buying a pack of 2 reduces the cost per unit compared with buying individually and simplifies stock management for those carrying out larger-scale smart home installations, such as new flats, offices or complete renovation projects.

Each device in the pack is installed in the electrical panel or in the wall box, behind the existing switch, and connects directly to the local WiFi network, with no additional hub. Control is via the Shelly app, the local web interface or integrations with Google Home, Amazon Alexa and Home Assistant.

Note: installation must be carried out by qualified personnel, as the devices work with mains voltage; each unit in the pack must be configured separately in the app after installation.

Practical use cases

• Mounted behind a conventional wall switch, it turns a room's lighting into a circuit controlled from the app, by voice command or automatically, without replacing the existing switch.
• Installed on the circuit of a recirculation pump or an electric water heater, it allows remote switching on/off and scheduling of operating hours to save energy.
• Integrated into a home automation system, it can automatically switch off sockets or lighting when the whole family leaves home, based on geolocation from the app.
• Used in an electrical panel to control outdoor lighting, it can be scheduled to switch on automatically at sunset and switch off in the morning.

Technical specifications

The pack is the efficient choice for projects with several identical circuits to control, offering the same level of functionality as buying individually, at an optimised cost.
