Sonoff RFR2 Wi-Fi + RF Smart Switch

The Sonoff RF R2 is a smart relay that can be remotely controlled over the internet, with a built-in timer function, similar to the Sonoff Basic R2, but also supports 433 MHz RF/radio control. 

The device is a WiFi equipped + 433 MHz radio controlled smart relay switch that can be connected to any electrical circuit to switch on/off any connected electrical device. It supports remote control via smartphone with iOS (Apple) or Android app and also has a timer function (scheduled on/off). It also has 433 MHz radio remote control.

The device also has a physical button. You can share the remote control with your family. It is the perfect solution for smart control of household appliances that don't need to be used all the time and need to be switched on/off periodically (e.g. aquarium air pump). Using the smart switch, you can switch on your appliances before you get home and conveniently set the timer to switch off to save energy and costs.

It is often used in conjunction with 433 MHz RF remote controls and wireless RF switches to control electrical appliances and lights with a wireless switch.
