Create and trigger your own scenes with a single tap. Shelly i4 Gen3 handles precise control of four independent inputs and, thanks to the Multi‑click feature, lets you assign up to 16 different actions (single/double/triple click and hold for each input). The modern ESP‑Shelly‑C38F processor with 8 MB flash ensures lightning‑fast response and reliable operation.
The device works without a central hub — configure everything in the Shelly Smart Control app over Wi‑Fi, and quickly add new devices via Bluetooth. For advanced integrations, MQTT, WebSocket, HTTPS, UDP, and TLS encryption with custom certificates are available, including KNXnet/IP for building automation.
