Shelly Plug S Gen3 is a small but powerful smart plug that enables intelligent control and monitoring of devices such as lamps, heaters, and other electrical appliances from anywhere. Thanks to Matter certification, the device works seamlessly with ecosystems from various brands and also supports Apple HomeKit, Amazon Alexa, and Google Smart Home. Integration is easy, and the plug does not require a separate hub to function – a Wi-Fi connection alone is sufficient.

This smart plug features built-in power consumption measurement and a multicolor LED indicator that displays real-time electricity usage. It is designed to enhance the energy efficiency and safety of your home or office. You can easily set schedules and automations that turn off unnecessary devices, save energy, and ensure that devices are not accidentally left on. Additionally, the night mode allows the LED indicator to be dimmed to a non-intrusive night light, for example, in a child’s room or hallway. The built-in Bluetooth and Wi-Fi functions also act as a network extender, so you can enjoy a more stable connection throughout your home. Furthermore, the plug includes overheat, surge, and overload protection for added safety.

Matter compatibility enables broad interoperability among various devices, while scripting features offer advanced customization options. For example, you can set an air purifier to automatically turn on when outdoor pollution levels rise or program the device to switch off a forgotten iron for improved safety. Built-in schedules and counters help automate device usage, such as turning off office equipment for the weekend or starting small heaters before you arrive home. This smart plug is designed to make your life more comfortable, energy-efficient, and safe, perfectly suited for both home and workplace.

Shelly smart home products support Amazon Alexa and Google Assistant virtual assistants. In addition to these, several other smart home systems/platforms are supported (check product-specific compatibility). Shelly products connect to a wireless Wi-Fi network and do not require a separate home automation controller to operate.
