📡 433MHz RF Remote Control — 4-Button Wireless (Works with SONOFF 4CH PRO R3, RF Bridge & More)
A simple 4-button 433MHz RF remote control for wireless control of any 433MHz RF-compatible device. Each button sends a unique RF code that can be paired (learned) with SONOFF 4CH PRO R3, SONOFF RF Bridge, Slampher, and other 433MHz learning-code receivers. Compact keyring-sized design with a sliding cover to prevent accidental presses. Battery not included (12V 27A).
433MHz RF remotes:
⚡ Key Features
- 4 Independent Buttons (A / B / C / D) — each button transmits a unique RF code; control up to 4 different devices or channels from one remote
- 433MHz Learning Code — works with any 433MHz receiver that supports learning-code pairing (SONOFF 4CH PRO R3, RF Bridge, Slampher, generic RF relay modules)
- Sliding Protective Cover — prevents accidental button presses in your pocket or on your keyring
- Compact Keyring Design — small enough to attach to your keys or keep in a drawer near the front door
- No WiFi or App Required — pure RF signal; works instantly even during load shedding as long as the receiver has power (e.g. gate motor battery backup)
- Long Range — typical range of 20–50m through walls (open air range even further); ideal for controlling devices from another room or outside
- Works with SONOFF 4CH PRO R3 — pair each button to a different channel to control 4 gate motors, lights, pumps, or appliances from a single remote
- Works with SONOFF RF Bridge — the RF Bridge converts each button press into an eWeLink smart scene trigger, enabling hybrid RF + WiFi automations
🏠 Perfect For
Gate & Garage Control
Pair button A to your driveway gate and button B to your garage door — both via a 4CH PRO R3. Works during load shedding when the gate motor runs on battery. Keep it on your car keyring.
Light Switching
Assign each button to a different light circuit via an RF-compatible relay. Walk into a room and press A for the main light, B for accent lighting — no rewiring, no app, no WiFi needed.
Elderly & Non-Tech Users
Physical buttons are simpler than phone apps. Give a remote to elderly family members or domestic workers so they can control smart devices without needing a smartphone or WiFi knowledge.
RF Bridge Scenes
Pair with a SONOFF RF Bridge to trigger eWeLink smart scenes. Press button C → all lights off + alarm armed. Press button D → garden lights on + gate opens. The RF Bridge converts each button into a WiFi action.
🔀 This Remote vs SONOFF RM433R2
Both are 433MHz RF remotes with learning codes. The generic 4-button remote is compact, keyring-sized, and budget-friendly — ideal for gate/garage use. The SONOFF RM433R2 is a premium 8-button remote with a wall-mount base, longer range, and a more refined design — better for whole-home control from a fixed location like a bedside table.
