Yes, the famous IoT (Internet of Things) from Sonoff/Itead Studio is finally here, on Cytron Marketplace. We like it because it is an actual consumer-grade product that can be used right out of the box, and because it uses the famous ESP8285 (which is similar to ESP8266) on the device, it can be hacked too :) Although you will void the warranty of the product, it never stops the maker spirit. So what is Sonoff Smart Switch, it turns your devices into the smart item. This RFR2 smart switch can also be paired with RM433 remote controller. Check this video for the unboxing, easy setup, pairing the RFR2 with eWeLink, and also the RM433 remote control, in less than 5 minutes :)

* Video shows the pairing using RFR3, is the same as RFR2

This is a WiFi Smart Switch that is possible to control connected devices via the eWeLink directly from your smartphone or ask it to turn on/off devices with Amazon Alexa and Google Assistant.

Unlike the BASICR3, RFR2 provides you extra control helper - the matched RM 433 remote controller. Just choose the control way you preferred, simply set a timer to let your devices switch on/off automatically at a pre-set time through a day. For example, prepare your coffee maker in the evening, and a cup of coffee is ready for you the next morning. Compatible with the IFTTT function, and you can make more actions happen to trigger other devices or receive a notification on your phone once the action was triggered.

Along with support for smart scenes, just set a device to turn on/off to make another or a boatload of devices turn on/off. The LAN control is designed for situations which no available Wi-Fi connection, or an unsteady Wi-Fi network environment. A convenient option that is share control is capable of allowing you to manage the same device with your family or friends together, simply share it on the eWeLink app to try.

Note: Sonoff RFR2 comes with a 433MHz RF receiver module. If you want a smart switch without RF function, please get yourself the Sonoff BASICR3.

Note: Sonoff RFR2 DOES NOT come with the 433MHz Remote Control, please get it separately here.

Note: As this device deals with HIGH VOLTAGE Electricity, please be cautious when using it.
