Sonoff 4CH Pro & Sonoff 4CH Pro R2

This product has been Discontinued.

Overview

Sonoff 4CH Pro & 4CH Pro R2 are 4 gang WiFi switches. They support switching among 3 working modes: interlock/self-locking/inching mode. 4CH Pro supports to set 0.25-4s delay in inching mode,  while 4CH Pro R2 supports to set 1-16s. This feature allows you to let your switch turn on for a few seconds then goes off, which works like a pulse switch. They integrate with a 433MHz RF receiver module, making them possible to be controlled by RF Remote. The Sonoff 4CH Pro smart switch is DIN Rail mounted.

Users can remotely turn on/off the connected lights/appliances by iOS/Android App eWeLink or 433MHz RF Remote. They can create 8 enabled single/repeat/countdown timers to automatically turn on/off at the specified time. The timers can run themselves even when the network is unavailable. To let the devices be controlled by their family, users can simply share the devices with their accounts and allow specified timers permissions. They can even create some scenes or smart scenes to trigger ON/OFF the switch.

In self-locking mode, users can turn on/off the 4 connected devices instantly and separately.

In interlock mode, users can turn on one device every time, and turn off other devices at the same time.

In inching mode, users can turn on the connected devices for 0.25-4s (Sonoff 4CH Pro) or 1-16s (Sonoff 4CH Pro R2) then auto-off.

Users can set some devices in inching mode, while the others in self-locking mode.
