Smart switch Shelly 1PM Mini Gen3 1P Wireless 110-240V

The Shelly 1PM Mini Gen3 is a compact Wi‑Fi smart switch with one channel and built‑in power metering, designed for controlling and monitoring small electrical appliances on 110–240V AC. With a maximum load of 8A and minimal dimensions (34 × 16 × 29 mm), it fits behind wall switches or inside sockets and provides remote control without a separate hub. The device supports Wi‑Fi and Bluetooth connectivity, offers scripting and smart scheduling, and stores historical power data for analysis.

Advantages

Small form factor allows installation in tight switch boxes or appliance housings while retaining full functionality including accurate power metering up to 8A. Gen3 hardware uses an 8MB Shelly chip for improved responsiveness and future firmware upgrades (Matter-ready). The unit works directly over Wi‑Fi with optional Bluetooth inclusion, supports dry contacts, custom scenes, mjS scripting, and integrates with Shelly Smart Control and common voice assistants.

Suitable for

• Automating and remotely switching lamps and lighting fixtures
• Monitoring and controlling small kitchen appliances (coffee makers, toasters) within 8A limit
• Making legacy electronics or fans smart by installing behind sockets or inside casings
• Energy monitoring of personal electronics and small household devices

Configure schedules, scenes or mjS scripts in the Shelly Smart Control app, enable power metering to view consumption data, and link with voice assistants if desired.

Recommendations

Use the Shelly 1PM Mini Gen3 for devices and circuits that draw up to 8A. For higher-power appliances, choose a switch with an appropriate current rating. Follow local electrical safety regulations during installation and, when unsure, have a qualified electrician perform the wiring. Regularly review stored power data to identify unusually high consumption and optimise usage.
