Wait please...

Cancel

Follow the standard procedure as with other devices; finally, name the device.

If there is an error, check and repeat the action:

  1. You may have entered the wrong WiFi password.
  2. Ensure your smartphone or tablet is connected to 2.4 GHz WiFi with internet.
  3. Sonoff is too far from the router and the WiFi signal is too weak. Move the device closer to the router.
  4. The WiFi LED blinks green twice every second: The Sonoff device has connected to WiFi, but the connection to the server was unsuccessful. Check your network connection to see if your router allows it or has MAC address blocking.

Operating Modes

You can switch between three operating modes: Inching / Interlock / Self-locking

1. Self-locking Mode

In self-locking mode, you can turn on/off 4 connected devices independently. For example, if you turn on CH1, the connected device will continue to operate. If you turn off the device, the connected device will stop.

Switch Configuration

The switches are S5, S6, K6, and K5.

WARNING: If you are switching S5, S6, K5, K6, disconnect the power supply. Whether you use DC or AC input, make sure to always unplug the power cord!!! It is very dangerous if you do not interrupt the power; new settings cannot be activated, and you may damage the device.

Note: Cut off the main supply before changing work mode.

S6 interlock /inching&self-locking switch: Switching to (0) enters interlock mode; switching to (1) enters inching & self-locking mode.

K5 inching/self-locking switch: From left to right, 1, 2, 3, 4 correspond to channel 1 (CH1), channel 2 (CH2), channel 3 (CH3), and channel 4 (CH4). Switch the switch down (0) for the respective channel to enter inching mode; switch the switch up (1) for the respective channel to enter self-locking mode.

Please note that if the S6 function is switched to position (0), your 4CH Pro is in interlock mode, and K5 cannot be set.

K6 is used to set the delay time for inching mode. From left to right are 1, 2, 3, 4 corresponding to CH1, CH2, CH3, CH4. For example, with the Sonoff 4CH Pro, switch all switches down (0000), the ramp-up time will be delayed by 4s (400ms); switch all switches up (1111), the delay time will be 0.25s (250ms).

Pairing with 433MHz RF Remote Control

Learning the 433MHz RF remote control: Each gang can support 1 RF key, meaning each gang can remember the last learned RF key. Quickly press one of the switches below twice, then press one of the ABCD buttons on the remote control. If learned successfully, the button will light up red, and the corresponding status indicator light will blink green 4 times. You can press the button to turn on or off the respective channel.

Deleting the 433 MHz remote control coding: S5 is the button to delete the 433 MHz code. Press and hold it until 4 green LEDs light up on the display.
