SONOFF 4CHPROR3 4-gang Wi-Fi Smart Switch

The Sonoff 4CHPROR3 is a powerful 4-gang Wi‑Fi smart switch that gives you full control over four different devices from one compact unit. It’s perfect for automating lights, appliances, fans, garage doors, or pumps—whether at home or in your workshop.

With support for 4 independent channels, you can control each device separately through the Smart Life or eWeLink app. Set timers, create schedules, and automate scenes easily from your phone. The switch connects to your 2.4GHz Wi‑Fi network and doesn’t need any extra hub.

This smart switch works with Alexa, Google Home, and other voice assistants. You can turn devices on or off using simple voice commands like “Alexa, turn off pump 2.” It’s ideal for hands-free operation when you’re busy.

The 4CHPROR3 supports three control modes: interlock, inching, and self-locking. This lets you configure how each relay behaves depending on your needs. For example, you can use inching mode for momentary actions like garage doors or interlock for safety controls.

Installation is flexible. It supports both AC (100–240V) and DC (5–24V) power input, and it includes DIN rail mounting support for easy setup in electrical panels or enclosures. Each relay supports up to 10A, making it suitable for high-load devices.

Safety is a top priority. The switch includes overload protection, fire-retardant housing, and manual control buttons for quick access. Even if the Wi‑Fi goes down, your saved schedules and timers still work offline.

Whether you’re automating a greenhouse, water system, or multi-room lighting, the Sonoff 4CHPROR3 is a smart, reliable choice. It brings professional-grade automation to your fingertips.
