Sonoff 4CH R3 WiFi Smart Switch:

• Sonoff 4CH R3 is a Wi-Fi smart switch with four groups. It is also intended to enable you to incorporate smart control into your current house. Moreover, it features four gangs that allow you to simultaneously control lights and other household appliances in four different rooms of your house.
• It is crucial to remember that the 4CHPRO R3 and 4CHR3 differ significantly in that the latter is built with an extra feature for RF control.
• In contrast to 4CH R2, self-locking, interlocking, and inching mode are immediately accessible through the application.
• To make things easier to use, customers can now set these three functioning modes on the eWeLink APP rather than the hardware itself.
• You can therefore activate the following modes: inching mode, which activates one connected device and causes it to turn off automatically after a predetermined amount of time (0.5 – 3600s), self-locking mode, which turns on and off four connected devices independently, and interlock mode, which turns on one connected device each time and turns off the other devices simultaneously.

Features:

• Utilize the APP to remotely manage linked lights or devices in three different working modes: inching, interlocking, and self-locking.
• Allow for timing scheduling so that gadgets turn on and off automatically
• Create personalized smart scenes to enable the linked device to activate other devices via a switch.
• Give other accounts access to the device's control permissions so they can operate together.
• Use your smartphone to check the ON/OFF state of gadgets in real time.
• When a device is in the power on state, users can configure its On/Off/Keep status before to a power outage and make sure it stays in that configuration after power is restored.
