Short Description
The Shelly 1PM Mini Gen3 is a compact smart switch with built-in power measurement, enabling remote control of electrical appliances via mobile phone, tablet, PC, or home automation systems. It operates standalone within a local Wi-Fi network or integrates with cloud-based home automation services. This device is an enhanced version of the Shelly Plus 1PM Mini, featuring a more advanced processor and increased memory for improved performance.
With internet connectivity, users can access, control, and monitor the device remotely from anywhere. The unit is designed for retrofitting into standard electrical wall boxes, behind power outlets, light switches, or other space-constrained locations.
It includes an embedded web interface for configuration, monitoring, and real-time control.
Main Features
- Smart Switch with Power Measurement: Functions as a smart switch with real-time power consumption monitoring for connected devices.
- Compact Design: Small form factor ideal for installations in tight spaces such as standard wall boxes, behind outlets, or switches.
- Remote Control: Supports remote operation via smartphone, tablet, PC, or home automation platforms.
- Local and Cloud Operation: Works independently on a local network and can be managed through cloud-based services.
- Enhanced Processor & Memory: Upgraded hardware ensures faster response times and better multitasking capabilities.
- Remote Access: Full remote access and monitoring possible from any location with internet access, provided the device is connected to Wi-Fi.
- Embedded Web Interface: Built-in web interface for intuitive device management and settings adjustment.
- BLE Gateway: Acts as a bridge between Bluetooth-enabled Shelly devices and the broader Shelly ecosystem—receives BLE signals and forwards them to the cloud or non-BLE devices locally.
- Wi-Fi Range Extender for IoT Devices: Extends Wi-Fi coverage by receiving, amplifying, and rebroadcasting the signal across a wider area.
- Scripting Support: Shelly Script Language Features
- Wide Integration Options: Compatible with third-party home systems using HTTP API, MQTT(s), Webhooks (HTTP/HTTPS), and UDP.
- KNX Integration: Supports KNXnet/IP communication.
- Advanced Scheduling: Enables complex automation rules based on date, time of day, weekdays, hours, minutes, and seconds.
Use Cases
- Appliance Control: Automate lights, fans, heaters, and other devices remotely.
- Power Monitoring: Track real-time energy usage to identify inefficiencies and optimize consumption.
- Home Automation Integration: Seamlessly integrate into smart home ecosystems to create custom scenes and schedules.
- Energy Efficiency Optimization: Use power data to detect high-consumption devices and make informed decisions to reduce energy waste.
- Remote Monitoring: Check and manage connected devices while away from home using internet-connected access.
- Space-Constrained Installations: Ideal for retrofits where physical space is limited.
