Shelly 2PM Gen4 blind/shutter actuator 2 channels, AC 110–240V, 2.4 GHz Wi‑Fi, 1.4 W, 8000 KB flash

Shelly 2PM Gen4 is a two-channel blind and shutter actuator for AC mains (110–240 V) designed to control roller shutters, curtains, awnings and other bi-directional AC motors. It offers integrated power monitoring, 8000 KB flash memory and multiprotocol connectivity so you can connect via 2.4 GHz Wi‑Fi, Zigbee, Bluetooth or Matter for flexible integration into existing smart home setups.

Advantages

The device combines two independent channels on a single phase with per-channel power metering, enabling accurate energy monitoring and local data storage. Multiprotocol support (Wi‑Fi, Zigbee, Bluetooth and Matter) increases compatibility with a wide range of smart home ecosystems. Additional features include slat angle control for venetian blinds, internal temperature protection, support for schedules, scenes and scripting, and operation as a Wi‑Fi/Zigbee range extender and Bluetooth gateway.

Suitable for

• Automating roller shutters, blinds and curtains driven by AC motors
• Retrofitting behind existing wall switches or sockets in residential installations
• Setups that require energy monitoring for each channel to track consumption
• Smart home systems that use Wi‑Fi, Zigbee, Bluetooth or Matter

When it may not be suitable

Not suitable for low-voltage motors or drives that require a dedicated controller; the unit is specified for AC mains 110–240 V. It may also be unnecessary in systems that already use a different specialized actuator protocol or where wired integration is mandatory without wireless components.

Key specifications

• Supply voltage: AC 110–240 V
• Channels: 2 independent channels on the same phase
• Power consumption: 1.4 W (device idle power)
• Wireless: 2.4 GHz Wi‑Fi (802.11b/g/n/ax), Zigbee, Bluetooth, Matter support
• Memory: 8000 KB flash
• Per-channel power metering with local data storage
• Control: cover (roller) position control and slat angle (tilt) control for venetian blinds
• Protection: internal temperature sensor for overheating protection
• Additional functions: supports schedules, scenes, scripting, HTTPS, MQTTS and Web Sockets

How to use

Install the Shelly 2PM Gen4 behind an existing switch or inside a flush-mounted box following local electrical regulations and wiring diagrams for AC motors. Connect motor wires to the actuator channels and supply mains to the unit. Configure the device using the Shelly Smart Control app or integrate it into your preferred ecosystem via Wi‑Fi, Zigbee, Bluetooth or Matter. Set motor limits and calibration for accurate position and slat angle control, create schedules or scenes, and enable energy monitoring to view consumption data.

What to consider before purchase

• Compatible motor type: designed for bi-directional AC motors operating on 110–240 V
• Space for installation: requires a flush-mounted box or similar enclosure behind the switch
• Network preference: choose devices and ecosystem according to your preferred protocol (Wi‑Fi, Zigbee, Bluetooth or Matter)
• Power and load requirements: verify motor current and electrical installation limits

Recommendations

For reliable operation, calibrate travel limits and slat tilt in the app after installation, enable the internal temperature protection, and use the per-channel power metering to detect abnormal motor loads or wear. When integrating into larger automation setups, prefer local actions and secure network configurations to maintain responsiveness and privacy.
