Sonoff Mini R4 – Extreme Wi-Fi Smart Switch

Transform your home into a smart home with the Sonoff Mini R4, an ultra-compact and powerful Wi-Fi smart switch designed to simplify your life. Whether you're automating lights, fans, or small appliances, the Sonoff Mini R4 makes it easy to control them from anywhere via your smartphone or voice assistant. With its small size and sleek design, the Mini R4 can easily be installed behind your existing light switches or outlets, ensuring that you retain control through traditional switches while also enjoying the convenience of remote automation.
The Sonoff Mini R4 works with your existing home Wi-Fi network (2.4GHz), allowing seamless integration with the eWeLink app, available for both Android and iOS devices. Once connected, you can schedule, monitor, and control your home appliances from anywhere, even when you're not at home. Plus, it works with voice commands through popular voice assistants like Amazon Alexa and Google Assistant, giving you hands-free control.
Key Features:
Two-Way Control: With the Sonoff Mini R4, you can retrofit your standard light switches to create a smart light system. The physical switch remains functional, but you gain the added benefit of remote control through the app.
Voice Control: The Mini R4 works with both Amazon Alexa and Google Assistant, allowing you to control your devices simply by speaking. Just say, "Alexa, turn on the living room lights," or "Hey Google, turn off the fan."
Compact & Durable Design: The small and sturdy casing of the Mini R4 makes it an excellent choice for tight spaces. With a dimension of only 39.5 x 33 x 16.8mm, it fits easily behind your existing switch or outlet without taking up much space. The durable PC V0 material ensures a long-lasting performance.
Multiple Control Options: Not only can you control your devices remotely through the eWeLink app, but you also have LAN control. For advanced users, the open device REST API allows you to connect and integrate the Mini R4 with your existing home automation system, such as Home Assistant, via LAN.
Smart Scheduling & Automation: Set up automated schedules for your appliances to turn on or off at specific times. Combine with smart scenes to trigger other devices based on conditions such as temperature, time of day, or motion detection. Your home becomes smarter and more energy-efficient.
Inching & Self-locking Modes: The Sonoff Mini R4 supports multiple modes, including inching mode (pulse control for push-button switches), edge mode (for SPDT switches), and following mode (for switches with ON/OFF marks and dry contact sensors). These flexible modes allow you to control a variety of devices like lights, fans, or even motors.
