Shelly i4 Gen3: Smart Wi-Fi Input Module for Advanced Control

Shelly i4 Gen3 is an intelligent, Wi-Fi-connected input module designed to provide extended control and automation in your smart home. This compact device installs discreetly behind existing wall switches, enabling manual activation or deactivation of scenes, synchronized actions, and complex trigger scenarios. With Shelly i4 Gen3, you can control other connected Shelly devices, sensors, or devices controlled via HTTP and MQTT.

Key Features:

• Four Digital Inputs: Connect up to four switches for versatile control of various functions and devices.
• Multi-Click Support: Each connected switch can be configured to recognize multiple press patterns (e.g., single click, double click, triple click, long press), allowing for up to 16 different commands or scenes from a single four-button switch.
• Powerful Processor and Extended Memory: Equipped with the new ESP-Shelly-C38F processor and 8MB memory, providing improved performance, faster response, and smoother operation. This also paves the way for future upgrades, including potential support for the Matter standard.
• Versatile Connectivity: Supports Wi-Fi (802.11 b/g/n) for network connection and Bluetooth for easy pairing and integration. Functions as a Wi-Fi range extender and Bluetooth gateway.
• Broad Integration Capabilities: Compatible with the Shelly Smart Control app, MQTT, Webhooks, HTTPS, UDP, TLS, custom scripts (mJS), and most popular home automation platforms and voice assistants like Google Home and Alexa. Also supports KNXnet/IP communication.
• No Hub Required: Connects directly to your Wi-Fi network without the need for a separate hub or gateway.
• Local and Remote Control: Control your devices and scenes locally at home or remotely via the internet. Also works without cloud connection for increased reliability.
• Compact Design: Its small size (approx. 37x42x16 mm) allows it to easily fit into standard switch boxes behind switches or in other spaces with limited room.
• Improved Terminals: Upgraded connection terminals for increased durability and easier installation.
• Scene Activation and Automation: Create custom scenes to, for example, turn off all lights and close blinds with a single click, or automate actions based on the status of other Shelly devices.

Use Cases:

Shelly i4 Gen3 is ideal for:

• Making traditional switches smart and integrating them into your smart home system.
• Creating advanced scene control for lighting, blinds, and other devices.
• Integrating motion sensors or other sensors to trigger automations.
• Expanding the functionality of your existing Shelly system.
