Sonoff RF R2 with eWelink wall panel 1 gang

Is Sonoff RF R2 compatible with eWelink 1gang wall panel or switch? I tried Sonoff Basic R2 and it cannot be paired with the wall panel switch which I think is RF!

I am trying to use 1 Sonoff RF R2 switch with two single gang wall switch panels. How do I pair them together like they do in eWelink Basic R2 using QR code?

Basic R2 is based on Wi-Fi while RF R2 is a RF bridge, they are two different protocols
Wi-Fi device → Wi-Fi router
RF device → RF bridge → Wi-Fi router

Got it! Now pls tell me How do I pair 2 RF switch panels to RF device?
