Description

The Shelly Plus 2PM Gen3 delivers extensive smart home functionality, allowing smooth remote control and automation of two separate electrical circuits, such as lights or curtains, or a bi‑directional motor used in motorised blinds. After a quick five‑minute installation, any connected appliance or system can be managed effortlessly through the free Shelly app over standard home Wi‑Fi, without the need for a specialised hub or additional wiring. The device also includes highly accurate power monitoring (within 1%) and securely stores energy‑usage data in the cloud for later review.

As an upgrade to the previous Plus 2PM model, the Gen3 introduces a new in‑house–designed chip with 8MB of memory, improving speed and overall responsiveness. It also adds Matter compatibility for simpler integration with existing smart home ecosystems, and supports KNXnet/IP communication to expand the range of possible integrations even further.
