## Long description

Sonoff 4CH‑PRO‑R3 is a 4‑gang smart Wi‑Fi switch designed to control four separate electrical circuits from a single device. It provides remote operation via the Sonoff mobile app, supports RF remote control and integrates with popular voice assistants for hands‑free control. Each channel can be switched independently and scheduled to run automated tasks, making it suitable for managing lights, sockets and small appliances in home or office environments.
Advantages
The device combines multiple control methods — Wi‑Fi app control, RF remote support and voice assistant integration — to provide flexible operation. Independent channel control and scheduling enable precise automation and energy management. Compact multi‑gang design reduces the number of separate controllers required and centralizes circuit control in one module.
Suitable for
Remote control of lighting circuits in residential rooms and corridors
Automated switching of wall sockets and small appliances
Integration into simple home automation scenarios and timed routines
Centralized control of multiple loads where independent switching is required
Key specifications
Four independent output channels for controlling up to four circuits
Wireless connectivity via Wi‑Fi for app control and remote access

Scheduling and timing functions for automated on/off events
Compact multi‑gang module form factor for installation in junction boxes or distribution enclosures
How to use
Install the unit according to local electrical regulations, connecting supply and load wires to the corresponding terminals for each of the four channels. Use the Sonoff mobile app to add the device to your Wi‑Fi network, configure each channel, and create schedules or scenes. Pair an RF remote if local wireless control is required. Enable voice assistant integration through the assistant’s service or skill to control channels by voice. Verify wiring and functionality after installation and test scheduled events and manual controls.
Usage recommendations
Use the switch for lighting circuits and low‑power appliances within the device’s rated load limits. Ensure installation is performed by a qualified person and verify that loads do not exceed the switch’s capacity. Keep the device’s firmware and mobile app updated for reliable operation and compatibility with voice assistant services.
