• Smart Switch with Power Measurement: Acts as a smart switch with the added capability of measuring power consumption, allowing you to monitor the energy usage of connected appliances.
• Compact Design: Designed as a small form factor switch, making it suitable for retrofitting into standard electrical wall boxes, behind power sockets, light switches, or other confined spaces.
• Remote Control: Enables remote control of electric appliances via a mobile phone, tablet, PC, or home automation system.
• Local and Cloud Control: Can function independently in a local Wi-Fi network and can also be operated through cloud home automation services.
• Improved Processor and Memory: Upgraded with an improved processor and increased memory for enhanced performance.
• Remote Access: Allows remote access, control, and monitoring from any location with internet connectivity, provided the device is connected to a Wi-Fi router and the internet.
• Embedded Web Interface: Features an embedded web interface for monitoring, control, and adjustment of settings.
• Wireless Connectivity: The device supports Wi-Fi (802.11 b/g/n) and Bluetooth 4.2 protocols with specified indoor and outdoor range capabilities.
• BLE Gateway: Bridge between your Shelly BLU devices and the wider Shelly ecosystem. It receives Bluetooth signals and sends them to the cloud or locally to another non-bluetooth device.
• Wi-Fi Range extender for IoT devices: A Wi-Fi extender is employed to expand the reach of your Wi-Fi network by receiving your current Wi-Fi signal, enhancing its strength, and then transmitting the enhanced signal over a wider area.
• Wide range of integrations: The device can be integrated with 3rd party home systems, documented HTTP API, MQTT(s), Web Hooks over HTTP and HTTPS, UDP
• KNX: Supports KNXnet/IP communication
• Schedules: Allows scheduling of complex operations to be executed in predefined time window. Users can specify time windows based on date, time of day, weekdays, hours, minutes and seconds.

• Appliance Control: Use it to remotely control and automate the operation of various electric appliances such as lights, fans, or other devices.
• Power Monitoring: Monitor the power consumption of connected appliances in real-time. This is useful for understanding energy usage patterns and promoting energy efficiency.
• Home Automation: Integrate the Shelly 1PM Gen3 into your home automation system to create custom scenes and schedules for your devices.
• Energy Efficiency: Leverage the power measurement feature to identify energy-hungry appliances and make informed decisions to improve overall energy efficiency in your home.
• Remote Monitoring: Keep an eye on your devices even when you’re away from home. The remote access feature allows you to monitor and control connected appliances from anywhere with internet connectivity.
