Shelly 2PM Gen3 – Smart Dual Channel Switch with Power Consumption Monitoring

Device Identification

• Device Name: Shelly 2PM Gen3

• Device Model: S3SW-002P16EU

• Device SSID: Shelly2PMG3-XXXXXXXXXXXX

• BLE Model ID: 0x1005

Short Description

Shelly 2PM Gen3 is a dual-channel smart switch that measures power consumption and enables cover control. It can be remotely controlled via mobile, tablet, computer, or home automation system. The device can be used locally on a Wi-Fi network or in cloud-based home automation services.

The device is improved from its predecessor with an enhanced processor and larger memory and supports Venetian blind control.

The device can be installed in standard wall boxes, behind electrical outlets or switches, or elsewhere where space is limited.

The device has a built-in web interface that allows the device to be monitored and controlled and settings to be adjusted.

Key Features

• Smart switch with power monitoring: monitors energy consumption of connected devices.

• Compact design: fits in small installation locations.

• Remote control: via mobile, tablet, computer, or home automation system.

• Local and cloud control: operates independently on Wi-Fi network or in the cloud.

• Enhanced processor and memory: better performance.

• BLE Gateway: relays Bluetooth signals to the cloud or other devices.

• Wi-Fi range extender: extends Wi-Fi signal coverage.

• Scripting and schedules: automation and schedule setup.

• Integrations: HTTP API, MQTT, Webhooks, UDP.

• KNX support: In Switch mode only with firmware ≥1.5.0.

• Virtual components: dynamically created components.

• Venetian blinds mode: remote control of motorized blinds, curtains, and window shutters. Measures the power consumption of the connected device. Recommended for use only with motors with electronic or mechanical limit switches. Controls blind/cover position and lamella tilt angle.

Use Cases

• Remote control and automation of devices (lights, fans, etc.).

• Real-time energy consumption monitoring and increased energy efficiency.
