Short description
Shelly 2PM Gen4 is a small form factor 2-channel smart switch with power measurement and cover control, which allows remote control of electric appliances through a mobile phone, tablet, PC, or home automation system. It can work standalone in a local Wi-Fi network or it can also be operated through cloud home automation services. The device also has improved processor and increased memory compared to its predecessor. The device supports Venetian blinds similar to it’s predecessor Shelly 2PM Gen3.
Shelly 2PM Gen4 can be accessed, controlled and monitored remotely from any place where the User has internet connectivity, as long as the device is connected to a Wi-Fi router and the Internet.
It can be retrofitted into standard electrical wall boxes, behind power sockets and light switches or other places with limited space.
Shelly 2PM Gen4 has embedded Web Interface which can be used to monitor and control the device, as well as adjust its settings.
The device has multi-protocol wireless MCU which provide Zigbee and Bluetooth connectivity ensuring a secure connection.
This device is compatible with Matter.
Main features
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: Upgraded with an improved processor and Zigbee connectivity for enhanced performance.
Zigbee Connectivity: Zigbee is available for inclusion purposes, which may be useful during the setup process.
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.
Dry Contact: Allows switching on and off of lower voltage devices.
Embedded Web Interface: Features an embedded web interface for monitoring, control, and adjustment of settings.
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.
Zigbee Range extender for IoT devices: A Zigbee extender is employed to expand the reach of your Zigbee network by receiving your Zigbee signal, enhancing its strength, and then transmitting the enhanced signal over a wider area.
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.

Venetian blinds mode: The Device enables remote control of motorized blinds, roller shutters, venetian blinds, awnings, etc. It measures power consumption of the connected device. It is recommended to use only motors with electronic or mechanical limit switches. The motor limit switches must be set correctly before connecting the Device to the motor.
Use cases
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 2PM Gen4 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.
