The Sonoff RM433R2 is an RF remote control with which you can easily operate other Sonoff products. The remote has additional functions when used with a Sonoff IFan03 Wi-Fi Fan & Light Controller and Sonoff D1 Wi-Fi Smart Dimmer.
The difference with the old model (RM433 ) is that the RM433R2 has a different type of battery. The R2 also has a new chip that ensures that the remote control can be used at greater distances.

This phenomenon is called 'ghost switching'. This can especially occur with Sonoff RF switches (like the RF R3, 4CH, T2 EU, etc.) when they are not linked to an RF trigger, such as a remote control, after installation. In this case, the device may inadvertently become paired with any nearby RF device that uses the same frequency. This problem can be solved by connecting the Sonoff RF switch with an RF device, such as the Sonoff 433MHz RF Remote, before it can connect with something else.
