Short description

Shelly 2PM Gen3 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.

Shelly 2PM Gen3 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 Gen3 has embedded Web Interface which can be used to monitor and control the device, as well as adjust its settings.

• Scripting: https://shelly-api-docs.shelly.cloud/gen2/ComponentsAndServices/Script

• 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/IPcommunication (Switch mode only with firmware 1.5.0 and later).

• 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.

• Virtual Components: https://shelly-api-docs.shelly.cloud/gen2/DynamicComponents/Virtual/

• 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.

  • Controls position of blinds, rollers, shades, venetian blinds, etc.

  • Controls tilt position of the slats of venetian blinds

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 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.

What are the differences between the different generations of Shelly products?

Each new generation adds more power, memory, and features:

Gen 1 offers basic control;

Gen 2 (Plus Series, Mini Series, Pro Series) adds Bluetooth, scripting, and better security;

Gen 3 improves performance, adds Matter (starting from firmware version 1.6.0 or newer) and advanced monitoring;

Gen 4 offers multi-protocol connectivity, featuring Wi-Fi 6, Bluetooth, Zigbee, and Matter.

Can I control the device via Bluetooth?

No, the protocol is used only for device inclusion, allowing for quick and easy setup through the Shelly Smart Control app.

For bluetooth control it is required to have another Bluetooth device such as Shelly BLU Button or Shelly BLU Motion to interact.

Additionally, Shelly devices can function as a BLE gateway, bridging Shelly BLU devices to your Wi-Fi network.

Is it possible to use the device without a hub?

Yes, Shelly devices (except for Wave devices) operate independently without the need for a hub. They connect directly to your Wi-Fi network, and you can control them via the Shelly Smart Control app, web interface, or through integrations with platforms like Google Home, Alexa, Home Assistant and Samsung SmartThings.
