Pack of 4 relays Shelly 2PM Gen3

This pack contains 4 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 blinds 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.

The 4-unit pack is designed for larger projects than the small packs, such as complete flats, offices or buildings with many identical circuits to automate, significantly reducing the cost per unit and simplifying procurement for installers.

Each device in the pack is mounted in the wall box, behind the existing switch or socket, and connects directly to the local WiFi network, with no additional hub. Control is via the Shelly app, the local web interface or through 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.
• Mounted in the wall box of the outdoor lighting circuit, it can be scheduled to switch on automatically at sunset and switch off in the morning.

Technical specifications

For large-scale projects with many identical circuits to automate, this 4-unit pack offers the best cost-effectiveness in the Shelly Gen3 range.
