Frequently Asked Questions

Q: What devices can I control with the KEBIDUMEI 433MHz RF remote control switch?

A: The KEBIDUMEI 5-in-1 RF remote control switch is compatible with a wide range of devices, including LED lights, ceiling fans, electric doors, automated curtains, and general home or commercial appliances running on AC 90–250V. It is suitable for use in homes, farms, offices, factories, laboratories, and supermarkets.

Q: How many transmitters can each receiver store, and can one transmitter control multiple receivers?

A: Each receiver can be paired with and store up to 20 individual transmitters. Conversely, a single transmitter can be paired to control multiple receivers simultaneously — making it easy to manage several devices from one remote. Transmitters and receivers must be paired before use.

Q: What are the three operating modes, and how do I switch between them?

A: The KEBIDUMEI relay receiver supports three operating modes: Momentary (output is active only while the button is held), Toggle (each button press alternates between on and off), and Latched (output stays on after pressing and remains until pressed again). You can configure the desired mode via the setup button on the receiver unit.

Q: Does this RF switch work through walls and other obstacles?

A: Yes. The 433MHz RF radio frequency signal is designed to penetrate walls, floors, doors, and boards. In open, unobstructed environments, the operating range extends up to 70 meters. Obstructions such as thick concrete walls may reduce the effective range somewhat, but the high reception sensitivity (>–105dBm) ensures strong, stable performance in most real-world installations.
