Flush WiFi Smart Switch

The Shelly 1 Gen3 is a compact, smart Wi-Fi switch with potential-free contacts for controlling electrical devices such as lights, sockets, or gates via smartphone, tablet, PC, or a home automation system. It can operate independently in a local Wi-Fi network or be controlled via cloud services.

Compared to its predecessor, the Shelly 1 Gen3 features an improved processor and 8 MB of memory, providing higher performance and more reliable operation.

The Shelly 1 Gen3 is particularly suitable for retrofitting: in wall boxes, behind light switches, sockets, or in places with limited space. It comes with a built-in web interface, allowing the user to check device status, adjust settings, and manage control functions.

Use Cases:

Device Control: Switch lights, heating, doors, or other appliances at home or remotely.

Home Automation: Use schedules and scenes to automate processes (e.g., lights at sunset).

Integration: Supports many smart home protocols (MQTT, Webhooks, etc.) without the need for an additional hub.

Voltage Flexibility: Works with 110-240 V AC as well as various DC voltages.

Versatility & Expandability: Ideal for home and office, new automation projects, smart lighting, garage doors, and more.
