Smart mini relay with current measurement – ​​Shelly 1PM Mini Gen4

The Shelly 1PM Mini Gen4 is a powerful smart home relay in an ultra-compact form factor that can not only switch electrical devices but also precisely measure their energy consumption. Its particularly small design allows it to fit even into tight switch and distribution boxes – ideal for retrofitting in both old and new buildings.

Mini format meets full performance

Although only a few centimeters in size, the Shelly 1PM Mini Gen4 offers the same powerful features as its larger siblings: precise switching, real-time current measurement, local control, and broad smart home compatibility. This makes the module perfect for use in sockets, lighting circuits, or electrical devices with up to 8 A power consumption.

Full connectivity – tailored to your needs

The Shelly 1PM Mini Gen4 supports Wi-Fi , Bluetooth 5.0 , and Zigbee , making it a perfect fit for any smart home system. The Bluetooth function makes initial setup particularly convenient, while Zigbee allows integration into mesh networks. Local control via Wi-Fi even works completely independently of the cloud.

Real-time energy measurement

Thanks to integrated power consumption measurement , you can see at any time how much energy a connected device actually consumes. Voltage, current, power, and energy consumption are precisely recorded and provided via the web interface, app, or API – ideal for everyday energy optimization.

Intelligent control – local and global

The Shelly 1PM Mini Gen4 is operated via the intuitive web interface directly on the local network – without the need for a cloud or app. If necessary, the optional Shelly Cloud can be used for remote access or automation, for example, during extended absences or for integration into smart home scenarios.

Open for your automations

Whether Amazon Alexa , Google Assistant , or Samsung SmartThings – the Shelly 1PM Mini Gen4 can be easily integrated into existing voice assistants and platforms. For advanced automation, you can use MQTT , HTTP API , webhooks , and even KNX net/IP . The integrated script engine ( Shelley Script ) also enables custom logic directly on the device.

More security in mini format

Integrated overheating and overload protection reliably protects the Shelly 1PM Mini Gen4 and the connected devices. Despite its small dimensions, the module meets the highest safety requirements – both for private and commercial use.
