The RF remote controller from Sonoff is a handheld 4-button device that uses 433 MHz wireless signals. It quickly links to Sonoff RF smart switches, relays, or hubs. You can carry it, hang it, or mount it—no wiring or internet needed.

Each press sends a signal to control connected devices. You can turn lights on or off, activate scenes, or trigger alarms. This RF remote controller works even during power or Wi‑Fi outages.

It runs on a CR2032 battery that lasts months, depending on usage. The buttons use touch-cover protection, so they won’t activate accidentally in your pocket. This device is lightweight (about 30 g) and made of metal and plastic for durability.

You can pair it with multiple Sonoff RF products. It supports easy learning mode for fast setup. And it works reliably up to 20 meters away in open spaces.

For added convenience, it includes a small hook or keyring slot. As a result, you can carry it in your pocket, hang it by your door, or attach it to your keychain.

This RF remote controller is ideal for quick and local smart control. Use it to switch lights when entering a room, activate scenes from your bedside table, or control devices without a phone or internet.
