Turn ordinary switches and sockets into smart ones. Shelly 1 Gen3 is a compact 1‑channel switch with a 16 A potential‑free (dry) contact, Wi‑Fi and Bluetooth (BLE gateway). It works without a hub, offers fast automations, compatibility with Alexa/Google Home and KNXnet/IP, and thanks to encryption and an IP55 rating, ensures reliable and safe operation.
