Sonoff 8-Key 433MHz RF Remote Controller | RM433R2
The SONOFF RM433R2 is an 8-button 433MHz RF remote controller that works without Wi-Fi. It supports SONOFF products with 433MHz RF and other devices that use the 433MHz protocol, and pairs directly with the SONOFF D1 smart dimmer and iFan fan/light controllers.
Color: White
Control Without Wi-Fi: The remote talks to devices directly over 433MHz RF, so it keeps working even when there is no Wi-Fi connection and you don't need to find your phone.
Works With SONOFF 433MHz Devices: Use it with SONOFF RF-enabled products such as the RFR2, 4CHPROR3 and D1 dimmer, or with the RF BridgeR2 to bring the buttons into eWeLink scenes.
Quick Pairing With D1 and iFan: The RM433R2 pairs directly with the SONOFF D1 smart dimmer and iFan fan/light controllers, giving each button a ready-made function such as on/off, brightness or fan speed.
8 Customizable Buttons: Assign the eight buttons to different devices or scenes, so one remote can control several rooms.
Easy Installation: Fix it to the wall with 3M adhesive tape or screws, or mount it on an 86-type junction box with the RM433R2 base bracket (sold separately).
Who it's for / Works with: SONOFF 433MHz devices including the D1 smart dimmer, iFan03 / iFan04, RFR2 and 4CHPROR3, plus the RF BridgeR2 433 hub.
Good to know: This listing is the remote only; the RM433R2 base bracket for 86-type boxes is sold separately. It is for indoor use and runs on one CR2450 3V button cell.
