Shelly 1 Gen 4 Smart Wi-Fi Switch

The Shelly 1 Gen 4 sets an entirely new industry standard for professional smart home automation setups. The cornerstone of this fourth-generation micro-relay is its native compatibility with the unified Matter standard, guaranteeing instant and robust out-of-the-box interoperability with major worldwide automation platforms. This simplifies multi-brand ecosystem integration, ensuring minimal latency and high-tier reliability for both smart residential and light commercial projects.

Retaining its highly-regarded hardware asset — independent potential-free dry contacts —, the Shelly 1 Gen 4 offers unmatched field flexibility. It functions perfectly for standard high-power switching (up to 16A) such as household sockets and lights, while remaining the ultimate safe solution for low-voltage triggers including garage door openers, motorized gates, central heating boilers, and electronic irrigation. Its beefed-up onboard processor allows it to run heavy local automation workflows and script-based logic entirely disconnected from external cloud infrastructures.

Engineered with professional installers in mind, the Gen 4 chassis features minor structural design enhancements for smarter cable management and structural isolation in tight junction boxes. With comprehensive, native integration for Home Assistant, Alexa, Google Home, as well as MQTT and advanced Webhooks, the Shelly 1 Gen 4 is the definitive long-term building block for cutting-edge IoT projects.
