Smart Relay Shelly 2PM Gen4 (Matter)

Shelly 2PM Gen4 Smart Relay (Matter) — Two-Channel Control, Energy Monitoring and Blind Automation

Shelly 2PM Gen4 (Matter) is a two-channel smart relay with built-in energy monitoring and support for Wi-Fi, Zigbee, Bluetooth and Matter. It can control two separate devices or run motorised blinds, curtains, awnings and Venetian blinds with adjustable slat angles.

Shelly 2PM Gen4 has a few useful upgrades over the Gen3 version. Matter, Zigbee and Bluetooth 5.0 are supported straight out of the box, while Gen3 mainly uses Wi-Fi and only gets Matter through a software update. Gen4 also has a faster processor, more memory and can help extend Zigbee and Bluetooth coverage. Wi-Fi 6 support makes it a good choice for newer smart home setups and future upgrades.

What can it do?

• Two separate channels on one phase — control two devices from one relay, such as a light and a fan.

• Energy monitoring for each channel — see how much electricity each connected device is using.

• Control blinds, curtains and awnings — open, close or stop them at the position you want.

• Adjustable slat angles — control how much daylight enters the room by changing the angle of Venetian blinds.

• Plenty of ways to connect — supports Wi-Fi, Zigbee, Bluetooth and Matter over Wi-Fi, making it easy to use with popular smart home platforms.

• Wi-Fi and Zigbee range extender with a Bluetooth gateway — helps improve coverage and keep your smart devices connected.

• Built-in temperature sensor — helps protect the relay from overheating and overload.

• Local and cloud control — use the Shelly Smart Control app, the web interface or your preferred integration.

• Scripts and API support — works with HTTPS, MQTTS, WebSockets and KNX for more advanced automation projects.
