This set of two miniature Shelly 1PM Mini Gen4 modules brings remote control of electrical appliances and accurate energy consumption metering in one. With support for Wi‑Fi, Zigbee, Bluetooth, and Matter, you can easily integrate it into a smart home, locally or via the cloud; the compact body also fits into standard wall mounting boxes behind a switch or outlet.
Shelly 1PM Mini Gen4 works as a smart relay and at the same time as a power meter for the connected circuit. It lets you turn devices on and off remotely, monitor real-time consumption, and better optimize energy costs. Setup is simple thanks to the built-in web interface—no need to install additional software.
Wide compatibility (including Matter) makes integration into common smart home ecosystems as well as advanced installations easier. Create automations, state-based actions, schedules, or integrations via API and network services.
