The compact dual-channel relay Shelly 2PM Gen4 in a set of 4 delivers precise control of blinds, roller shutters, curtains, and electrical circuits with independent power measurement on each channel. It offers fast and stable operation thanks to an improved chip, wide connectivity (Wi‑Fi, Zigbee, Matter, Bluetooth), voice control via Amazon Alexa/Google Home/Apple HomeKit/SmartThings, and advanced automations, scenes, and scheduling. Ideal for standard wall boxes, with safety protections and both local and cloud control.
Smart relay for shades and appliances
Shelly 2PM Gen4 manages two independent circuits, so you can easily set the blind position and slat angle or control lighting in two rooms from a single module. With per‑channel energy monitoring you get real‑time insight into consumption and can optimize the operation of your home or office.
Maximum compatibility and easy installation
Support for Wi‑Fi, Zigbee, Matter, and Bluetooth ensures flexible integration even into existing systems. Control via Amazon Alexa, Google Home, Apple HomeKit, and Samsung SmartThings is instantaneous, and it works locally without external servers thanks to the built‑in web interface. The compact size fits standard installation boxes.
Safety and performance
Integrated protections against overheating, overvoltage, overload, and overpower along with an internal temperature sensor ensure reliability. The device can also act as a Wi‑Fi and Zigbee range extender and a Bluetooth gateway, and it supports HTTP/HTTPS, MQTT, Webhooks, and UDP for advanced scenarios and integrations.
