Description
Shelly Plus 2PM 2-Channel Wi-Fi Smart Switch with Power Monitoring
Control two electrical circuits or automate a motorised cover with the Shelly Plus 2PM – a compact dual-channel smart relay combining independent switching, individual power monitoring and dedicated roller shutter control in one device.
Use it in Relay mode to control two separate lighting or appliance circuits while monitoring their energy consumption independently. Alternatively, select Cover mode to control compatible bi-directional AC motors, such as those used in roller shutters, blinds, curtains and awnings. Cover mode also supports position control, obstacle detection and a safety switch.
Key Features
- Two Independent Channels – Control two separate circuits on the same electrical phase, with up to 10A per channel and 16A combined on AC.
- Individual Power Monitoring – Monitor the power consumption of each output separately, helping you understand and manage energy usage.
- Cover and Roller Control – Operate compatible bi-directional AC motors used in roller shutters, blinds, curtains, awnings and pool covers, with adjustable position control.
- Obstacle Detection and Safety Switch – Additional safety features when operating in Cover mode.
- Flexible Power Supply – Supports 110–240V AC or 24V DC power.
- Compact Retrofit Design – Measuring just 37 × 42 × 16 mm, it fits into many standard electrical wall boxes and behind switches.
- Wi-Fi and Bluetooth – Connects directly to your Wi-Fi network without requiring a separate hub. Bluetooth is used for convenient device setup.
- Local and Cloud Control – Operate the device through its built-in web interface, local Wi-Fi network or compatible cloud services.
- Advanced Automation – Supports schedules, scenes, mJS scripting, MQTT and HTTP/HTTPS webhooks.
- Shelly Plus Add-on Support – Includes an interface for the optional Shelly Plus Add-on.
Ideal Applications
- Automating two separate lighting circuits from one module.
- Monitoring the energy consumption of two appliances or circuits.
- Motorising roller shutters, blinds and curtains.
- Automating compatible awnings and pool covers.
- Integrating switching and motor control into Home Assistant and other smart-home systems.

Important Installation Notes
- AC operation requires a neutral wire. For 24V DC operation, follow the manufacturer’s DC wiring diagram.
- The two channels operate on the same phase; they are not intended for switching separate phases.
- In Cover mode, both outputs are used to operate one compatible bi-directional motor. You cannot use the device as two independent relay channels at the same time.
- Inductive loads such as certain fans, transformers and motor-related loads may require an appropriate RC snubber.
- The optional Shelly Plus Add-on interface can carry hazardous voltage when the device is powered. Follow the manufacturer’s installation instructions carefully.
- Professional installation by a qualified electrician is recommended.
Product Availability
The Shelly Plus 2PM has been discontinued by the manufacturer. Its recommended successor is the Shelly 2PM Gen3, which offers a newer hardware generation.
