Shelly 1PM Mini Gen4 2-pack — Shelly Wi-Fi smart relay with power metering, compact DIN/module form

Shelly 1PM Mini Gen4 2-pack are two compact Wi‑Fi smart relays with integrated power metering, designed for installation in tight spaces such as inside wall boxes or on DIN rails. Each relay controls a single circuit, enabling remote switching over a local network or cloud service and providing real‑time consumption data for connected loads. The small module form factor fits behind switches or inside distribution cabinets to automate lighting, small appliances and other low‑power circuits while delivering energy usage feedback for efficient operation.

Advantages

The Shelly 1PM Mini Gen4 offers accurate real‑time power metering alongside reliable Wi‑Fi based remote control, all in a compact module suitable for confined installation spaces. Built for simple integration, it supports schedules and scenes and can work with third‑party automation platforms that accept standard smart relay protocols. Installation flexibility and local telemetry reduce the need for separate energy meters and simplify load management for homes and small commercial sites.

Suitable for

• Automating indoor lighting circuits in residential or small commercial settings
• Remote switching and monitoring of small household appliances and pumps
• Energy tracking for individual circuits to identify consumption patterns
• Integration into home automation setups for scheduling and scene control

Key specifications

• Form factor: compact module suitable for in‑wall or DIN‑rail installation
• Control: single relay channel for one circuit
• Connectivity: Wi‑Fi for remote control and telemetry
• Function: integrated real‑time power metering for connected load
• Typical applications: lighting, small appliances and low‑power circuits

How to use

Place each Shelly 1PM Mini Gen4 inside a suitable installation box or on a DIN rail near the circuit to be controlled. Connect line, load and neutral according to local electrical regulations, then provide power to the module. Use the Shelly app or compatible home automation software to connect the relay to a Wi‑Fi network, configure device parameters, and enable power monitoring. After setup, control the circuit remotely, create schedules or scenes, and monitor real‑time and historical energy data through the app or connected automation system.

Recommendations

Ensure installation is performed by a qualified electrician and complies with local wiring regulations. Verify the connected load is within the relay’s rated capacity before use. For reliable Wi‑Fi operation, place the module where it can access a stable network signal or consider using a Wi‑Fi extender in larger installations.
