SONOFF 4CH Pro R2 DIY 4-Way WiFi Wireless Smart Switch Remote Control

Sonoff 4CH Pro & 4CH Pro R2 are 4 gang WiFi switches. They support switching among 3 working modes: interlock/self-locking/inching mode, and both supports to set 1-16s delay in inching mode. 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 433.92MHz RF receiver module, making them possible to be controlled by RF Remote. The smart switches are 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 others, users can simply share the devices to other accounts and allow specified timers permissions. Users can even create some scenes or smart scenes to trigger ON/OFF the switch

• Upgraded: Sonoff 4CH Pro supports to set 1-16s delay in inching mode now ( 0.25-4s before)
