Sähkörele Shelly i4 Gen3 oranssi Wi‑Fi 2,4 GHz 1 W 110–240 V 4-kanava

The Shelly i4 Gen3 is a compact Wi‑Fi operated 4‑digital input controller designed to be installed behind standard wall switches. It provides manual control of scenes and devices, supports multi‑click actions and scripting, and connects directly to a 2.4 GHz Wi‑Fi network without a hub. With wide voltage support (110–240 V AC), low power consumption (typical 1 W), and a small form factor (42 × 37 × 17 mm), the orange Shelly i4 Gen3 is suitable for retrofit installations and integration with other Shelly devices or third‑party products via HTTP and MQTT.

Advantages

Shelly i4 Gen3 offers Bluetooth and Wi‑Fi connectivity for easy setup and operation, up to 16 configurable actions via multi‑click support, and full mjS scripting for custom behavior. It uses Shelly’s own Gen3 chip with 8 MB memory for improved performance and smoother future updates, and is designed to be upgradable to Matter. Virtual components in the Shelly Smart Control app allow integration of non‑Shelly devices into a unified control interface.

• Retrofit installation behind existing 4‑button wall switches
• Triggering scenes and automations for lights, blinds, and security
• Controlling other Shelly relays, sensors, or devices via HTTP/MQTT
