Sonoff 4CH Pro is an ESP8285 WiFi module based 4 channel (4-way) WiFi wireless switch. It integrates with MCU ST32F030C6 and 433MHz receiver. Sonoff 4CH Pro supports to connect and control 4 home appliances, which can be separately turned on/off by app eWeLink and 433MHz remote. Users can switch among 3 modes: self-locking mode, inching mode and interlock mode. In self-locking mode, users can turn on/off the 4 connected devices independently. In inching mode, users can turn on connected devices for 0.25-4s.In interlock mode, users can turn on 1 device every time, and turn off other device at the same time.

The enclosure supports din-rail mount! A DIN rail is a metal rail of a standard type widely used for mounting circuit breakers and industrial control equipment inside equipment racks.

Sonoff 4CH is hacker-friendly! You can flash external firmware!

Specification

Hardware

Working Mode

Sonoff 4CH Pro supports to work 3 modes: self-locking mode, inching mode and interlock mode.

In self-locking mode, users can turn on/off the 4 connected devices independently. For example, if users turn on CH1, connected device keeps on. If users turn off CH2, connected devices keeps on.

In inching mode, users can turn on the connected devices for 0.25-4s. For example, users can turn on CH1 connected device for 1s, then auto-off.

In interlock mode, users can turn on 1 device every time, and turn off other device at the same time. For example, if users have turned on CH2, then they turn on CH3, CH2 will be auto turned off at the same time.

We will introduce how to switch among the 3 modes below:

CAUTION: Please cut off main supply before switching S5, S6, K5, K6. Make sure you have unplugged the power plug every time!!!

S6 is inching/interlock switch: Toggle to the right(0), it enters into interlock mode; Toggle to the left(1), it enters into inching mode.

S5 is code clearing button: To clear the 433MHz codes, please press and hold it until the 4 LEDs turn off.

K5 is inching/self-locking switches: From left to right, there are 1, 2, 3, 4, correspondingly for channel 1 (CH1), channel 2 (CH2), channel 3 (CH3), channel 4 (CH4). Toggle the switch down (0), the corresponding channel enters into self-locking mode; Toggle the switch up (1), the corresponding channel enters into inching mode.

  • Please note that if S6 is toggled to the right(0), it enters into interlock mode, it’s invalid to set K5.

K6 is used to set the delay time for inching mode. From left to right there are 1, 2, 3, 4, correspondingly for CH1, CH2, CH3, CH4. Toggle all switches down (0), the inching time will delay for 0.25s; Toggle all switches up (1), the inching time will delay for 4s. Please refer to the setting list below:

Pair with 433MHz RF Remote: Quickly press twice one of the switches below, then press one of the ABCD buttons on your RF Remote. If paired successfully, the button will lit up in red, and the corresponding status LED will blink in green for 4 times. You can press the button to turn on or turn off the related channel.
