SONOFF RFR2 - สวิตช์อัจฉริยะไร้สาย WiFi พร้อมตัวรับสัญญาณ RF สำหรับบ้านอัจฉริยะ

I'm not much of a tech person, but wiring this into the middle of my lamp's power cord was way easier than I expected, and now my old 433MHz remote controls it from anywhere in the house. Even when the Wi-Fi drops, the RF still works, which is a relief since I use it for my garage light.

The 433MHz RF receiver picked up my existing remotes instantly, so I wired it into the power line and now I can switch lamps on from the sofa. It’s nice that it works even when the WiFi drops, which my other smart plugs can’t do.

Paired it with my old 433MHz garage remote and it flipped my lamp on from across the yard without any Wi-Fi involved—that offline RF pass-through is exactly what I needed. Setup was a bit fiddly getting the wires seated, but once it clicked, it's been rock solid for a week.
