Short description
Shelly Plug PM Gen3 is a smart plug/outlet with power measurement capabilities, which allows remote monitoring of electrical appliances. It enables users to track and analyze energy consumption patterns, helping to optimize power usage and prevent energy waste.
Due to its built-in web interface, the device can be accessed, set up, and monitored remotely from anywhere with internet connectivity, as long as it's connected to a Wi-Fi router and the Internet.
Main features
- Wi-Fi smart plug with multicolor LED indication
- Scripting
- Wi-Fi range extender
- BLE gateway
- Power metering
- Wide compatibility with 3rd party home automation systems
- Shelly Cloud / Shelly Smart Control app support (optional)
- Virtual Components
Use cases
- Color night light: Use the device's LED indication to adjust your color light night. Night mode reduces the brightness of the LED indication during night hours so you can have undisturbed sleep.
- Energy monitoring: Track real-time energy consumption of appliances like refrigerators or heaters, identify high-energy devices, and reduce power usage.
- Usage analysis: By monitoring energy consumption patterns over time, make informed decisions about when to use appliances more efficiently or upgrade to more energy-efficient models.
- Overload notification: The plug provides alerts if connected devices are drawing too much power, helping prevent potential damage or overheating.
- Cost estimation: Estimate the operational costs of specific appliances, enabling better budget management by understanding how much each device contributes to the electricity bill.
