The SONOFF RM433R2 is an updated RF remote controller operating at 433MHz, equipped with an improved chip compared to the original RM433. Its 8 buttons enable independent control of multiple devices or multiple functions on a single device — such as adjusting fan speed, changing lighting intensity, or toggling a device on and off.

Pairing with a supported device requires only a single button press on the remote. The RM433R2 is compatible with SONOFF RFR2, RFR3, SlampherR2, iFan03, iFan04, D1, the TX series, 433 RF BridgeR2, and other devices that support the 433MHz communication protocol.
