Description
SwitchBot 2PM Relay Switch, Dual-Channel Smart Switch
The SwitchBot Relay Switch 2PM is the world's first smart relay with a built-in Bluetooth repeater and Matter support, connecting devices from different brands into a single ecosystem. Compatible with Alexa, Apple HomeKit, Google Home, and SmartThings, it lets you conveniently control lights, blinds, fans, or heating from anywhere. Its compact design (42 × 36 × 16 mm) makes it easy to install in a junction box without modifying the wiring.

Modernization without renovation
Installed behind a traditional switch, the Relay Switch 2PM transforms standard circuits into smart solutions without the need for renovations. Installation takes just a few minutes, and you can then manage lights and devices via an app or voice commands. The device supports both Wi-Fi and Bluetooth, and the Matter protocol allows direct connection to popular voice assistants without the need for an additional hub.

Energy savings monitoring
The model also offers energy measurement on two independent channels. The SwitchBot app provides detailed graphs of power, current, voltage, and total energy consumption, allowing you to optimize costs and effectively manage your home's energy. Data is stored for free for 2 years, facilitating long-term analysis.

Flexible control and automation
Thanks to support for various switch types (toggle, momentary, separate, and onboard), the device offers maximum installation flexibility. You can create automatic scenarios, such as turning on the lights when the door is opened, lowering the blinds at sunset, or controlling the heating based on SwitchBot Meter Pro's sensors.

High level of security
The SwitchBot 2PM relay stands out for its robust construction and class V0 fire protection. The protection system automatically interrupts the power supply in the event of overload or overheating above 100°C and restores the previous operating state once the fault has been eliminated. This ensures that your electrical system remains safe at all times.

The relay can integrate up to 10 SwitchBot Bluetooth devices, such as Lock Pro locks, Curtain 3 shutters, or Meter Pro sensors, creating a complete and integrated home automation system.
