Open box Smart relay Shelly 1PM GEN3, 1 channel, 16A, WiFi, energy monitoring function

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 1PM Gen3 is a single-channel WiFi smart relay with power metering, designed for remote control of electrical appliances with real-time consumption monitoring. The relay supports up to 16A and provides accurate data on the energy consumed, stored free of charge in the cloud for long-term analysis and optimisation.

It is ideal for controlling water heaters, pumps, light fittings or other equipment where consumption monitoring matters as much as simple on/off control. By tracking consumption, the user can identify inefficient appliances, set high-consumption alerts or calculate real running costs.

Like the other generation 3 models, it uses the ESP-Shelly-C3F processor with 8 MB of memory, mounts discreetly in the wall box and supports WiFi and Bluetooth 4.2. It is Matter certified (after a firmware update), which allows direct integration into modern smart home ecosystems, alongside the existing support for Google Home, Alexa and other platforms.

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.
