Extremely compact smart switch with potential-free contacts, Wi-Fi repeater, and Bluetooth gateway functionality – ideal for retrofitting without a hub.
The Shelly 1 Gen3 is an ultra-compact smart switch with potential-free contacts, perfect for integration into conventional flush-mounted boxes without a neutral wire. It also serves as a Wi-Fi range extender and Bluetooth gateway. Thanks to the powerful ESP-Shelly-C38F processor with 8 MB of memory, it enables control and automation via scripting, webhooks, MQTT, WebSocket, HTTPS, UDP, TLS, as well as integration into platforms like Alexa, Google Home, or Home Assistant – all without a hub. Matter support is available starting with firmware 1.6.0.
