Frequently Asked Questions

Q: What devices can I control with this 433MHz wireless relay switch module?

A: This relay module can control any resistive or inductive AC load up to 10A at 90–240V, including LED lights, incandescent bulbs, LED strip controllers, small fans, and other low-current appliances. Always verify the load current does not exceed the 10A rating.

Q: How do I pair (learn) a new remote transmitter to the receiver?

A: The receiver uses 1527 learning-code technology. Briefly press the learn button on the receiver module, then press the button on your transmitter — the receiver will store the code. You can store up to 15 different remotes. To clear all stored codes, hold the learn button for several seconds until the indicator flashes.

Q: What is the effective wireless range of this RF 433MHz module?

A: In open space the range exceeds 50 metres. In typical indoor environments with walls and obstructions you can expect 20–30 metres. The superheterodyne receiver design provides strong signal sensitivity (>97 dBm) to maximise reliable operation.

Q: Does this module work with other 433MHz remotes I already own?

A: Yes — as long as your existing remote uses a 433MHz learning code (1527-type), it can be paired with this receiver. It is not compatible with fixed or rolling-code protocols used in some garage-door openers or alarm systems.
