Shelly Plug M Gen3 – Wi-Fi + Bluetooth, Matter-compatible smart plug with energy monitoring, black

The Shelly Plug M Gen3 is a smart plug with built-in power monitoring designed for remote control, energy consumption tracking, and smart automation of electrical appliances. It can be used to automate lamps, fans, portable heaters, coffee machines, televisions, washing machines, and many other household devices without replacing the original appliance.

The device features both Wi-Fi and Bluetooth connectivity, allowing direct connection to the home network without the need for a dedicated hub. Thanks to Matter support, it can easily integrate with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Home Assistant systems.

The Shelly Plug M Gen3 includes built-in energy monitoring functionality capable of displaying real-time voltage, current, power consumption, and energy usage data. It is an excellent choice for energy optimization tasks and monitoring high-consumption devices, helping reduce unnecessary electricity costs.

The device supports schedules, automatic ON/OFF switching, local automations, webhooks, MQTT integration, and scripting functionality. Timers and automations can run locally even without internet access, ensuring reliable operation independently from cloud connectivity.

The Shelly Plug M Gen3 also functions as a BLE Gateway and Wi-Fi range extender. It enables integration of Shelly Bluetooth sensor data into the smart home system while improving Wi-Fi coverage for other Shelly devices through the built-in Wi-Fi extender feature.

The smart plug is ideal for automations such as automatic heater control based on temperature, washing machine or dishwasher cycle monitoring, reducing energy waste with automatic shutdowns, or presence simulation while traveling.

About the Shelly Brand

Shelly is one of the most recognized and innovative smart home brands in Europe, developed by the Bulgarian company Allterco Robotics. The manufacturer is particularly strong in the market of Wi-Fi and Bluetooth-based smart devices, whose main advantage is that they generally operate without a central hub, allowing quick and easy installation using only a working Wi-Fi network.

The Shelly product portfolio is extremely broad and includes relays, sensors, smart plugs, lighting solutions, and professional DIN rail mounted devices. The brand places strong emphasis on local control, meaning devices can continue operating without internet access, improving reliability and data security.

Shelly devices offer advanced integration capabilities with native support for REST API, MQTT, and Webhook communication, making them easy to integrate with systems such as Home Assistant, openHAB, Node-RED, and other DIY solutions. They are also compatible with popular cloud platforms including Google Home, Amazon Alexa, and Samsung SmartThings.

The manufacturer continuously develops its products, and the latest generations already include Bluetooth gateway, Wi-Fi range extender, and additional networking functions. Shelly products are especially popular among advanced users and installers while remaining simple enough for beginners.
