Description

The Shelly Plus 1PM Gen3 offers a significant improvement over the earlier Shelly Plus 1PM, featuring a redesigned chip with 8MB of memory that provides smoother operation, better efficiency, and faster response times.

The Gen3 version also adds support for virtual components and can be upgraded to Matter, helping ensure long‑term compatibility within a smart home setup.

Thanks to its compact design, the Shelly Plus 1PM Gen3 can be retrofitted into existing electrical appliances such as lamps and heaters. It fits easily into tight electrical boxes and wall sockets, allowing you to convert them into fully smart, WiFi‑connected devices in as little as ten minutes.
