Couldn't load pickup availability
Ultra-compact at 29 × 34 × 16 mm, the Shelly 1 Mini Gen3 home automation relay switch fits into the narrowest switch boxes without compromising on performance. Powered by the new ESP-Shelly-C38F processor with 8MB of flash memory, it supports up to 8A at 240V AC, operates without a hub, and can be controlled from the Shelly Smart Control app, Alexa, or Home Assistant.
Scripts, MQTT, webhooks, and KNX: total flexibility for advanced installations
What sets the Shelly 1 Mini Gen3 home automation relay switch apart from classic relays is the breadth of its protocols: MQTT, WebSocket, HTTPS, UDP, TLS with custom certificates, webhooks with up to 20 actions and 5 URLs per trigger, and KNXnet/IP communication for professional installations. Up to 20 configurable schedules and an integrated scripting engine allow for complex local automations without relying on the cloud. Its Wi-Fi repeater and Bluetooth gateway functions also extend your installation's network coverage without additional hardware.
The Shelly 1 Mini Gen3 home automation relay switch fits in a standard flush-mounted box
Weighing 19 grams and designed for small spaces, the Shelly 1 Mini Gen3 home automation relay switch can be installed behind an existing switch without modifying the electrical panel. The potential-free dry contacts offer compatibility with a wide variety of loads: lighting, shutters, heating systems, or any circuit up to 2000W at 240V AC. The Wi-Fi 802.11 b/g/n covers up to 30 meters indoors and 50 meters outdoors, and the integrated Bluetooth 4.2 serves as a gateway for nearby BLE sensors and devices. It operates from -20°C to 40°C, making it suitable for less heated technical spaces.
FAQ
