About Product
- This Sonoff 4CH Pro R3 switch contains 4 separate Sonoff (RF) switches with a number of very useful features.
- In addition to the mains voltage, the Sonoff can now also be connected to direct current (5V to 24V) and can be placed in both locking and interlocking (1 relay switched on at the same time) mode.
- A timer from 1s to 16s can be set to switch off the relay.
- In addition, the time schedules will no longer be confused when the internet goes down, because this Sonoff keeps these settings offline!All channels can be individually controlled via the eWeLink app.
- This switch is based on the well-known ESP8266 and works over a WiFi connection with which devices can be switched on and off via the cloud. In addition, it is possible to control these switches 'smartly', for example the automatic switching of devices based on time.
