Description

The Sonoff 4CH PRO R3 is a professional-grade, multi-channel smart switch designed for integrating advanced automation into residential and light commercial environments. It operates on 100-240V AC and communicates via robust 2.4GHz WiFi (802.11 b/g/n) with WPA/WPA2 security, ensuring reliable connectivity for remote management through the eWeLink platform. A key upgrade from previous models is the inclusion of an integrated 433MHz RF receiver, allowing for additional control via compatible wireless remotes.

This unit distinguishes itself with software-configurable operational modes—Self-Locking, Interlock, and Inching—which are set directly within the eWeLink app instead of via physical hardware jumpers. This flexibility allows a single device to manage diverse loads, from simple on/off lighting control to timed motor operations for blinds or gates. Its DIN-rail mountable design and compact form factor make it ideal for centralized installation in distribution boards, enabling the smart control of devices located away from traditional wall switches.

Key Features

  • Four independent relay channels, each rated for 10A/2200W AC load (40A/8800W total).
  • Dual-control connectivity via 2.4GHz WiFi and integrated 433MHz RF receiver for remote operation.
  • Three software-configurable working modes: Self-Locking (individual control), Interlock (one-at-a-time), and Inching (timed auto-off from 0.5 to 3600 seconds).
  • Full compatibility with Amazon Alexa and Google Assistant for voice control and smart scene automation.
  • Schedule timers, create smart scenes, and share device control with other eWeLink accounts.
  • Power-on state memory allows pre-setting device status (On/Off/Keep) to resume after a power outage.
  • Designed for DIN-rail mounting with a flame-retardant PCV0 enclosure for safe electrical cabinet installation.

Applications

  • Centralized smart lighting control for multiple rooms or zones in residential buildings.
  • Automation of motorized devices like garage doors, roller blinds, gates, and curtains using Inching mode.
  • Remote control and scheduling of high-power appliances (heaters, pumps, fans) in home workshops or sheds.
  • Integration into smart home ecosystems for voice-activated scenes via Alexa or Google Home.
  • Professional electrical installations requiring DIN-rail mounted, multi-channel relay control.

Frequently Asked Questions

How do I connect the Sonoff 4CH PRO R3 to my home WiFi network?

Download the eWeLink app, create an account, and power the switch. Press and hold the button on the device until the LED flashes rapidly, then follow the in-app pairing steps to connect it to your 2.4GHz WiFi network. Ensure your phone is connected to the same network during setup.

What are the three working modes and how do I set them up?

The modes are Self-Locking (independent on/off per channel), Interlock (only one channel on at a time), and Inching (auto-off after a set duration). Configure them directly in the eWeLink app under the device settings, removing the need for physical jumper changes on the hardware itself.

Can I control this switch without an internet connection?

Local control via the eWeLink app is possible if your phone and the switch are on the same LAN. For full remote access and voice assistant integration (Alexa/Google Home), an active internet connection is required. The integrated 433MHz RF receiver also allows control via compatible wireless remotes independently of WiFi.

What is the maximum load I can connect to each channel?

Each of the four relay channels supports a maximum load of 10 Amps at 220V AC, equating to 2200 Watts. The total combined load for all four channels operating simultaneously should not exceed 40 Amps or 8800 Watts to ensure safe operation.

How do I mount the Sonoff 4CH PRO R3 in my electrical panel?

The switch is designed for standard DIN-rail mounting (35mm). Simply hook the top of the device onto the rail and press the bottom until it clicks into place. Ensure all high-voltage wiring is performed by a qualified electrician in accordance with local regulations.
