Frequently Asked Questions
Q: Is the RF433 wireless relay receiver module compatible with Wi-Fi or Zigbee smart home systems?
A: No. This module operates exclusively on the 433.92 MHz RF band and is not compatible with Wi-Fi or Zigbee networks. It pairs directly with standard 433MHz RF remote controls using learning-code technology.
Q: What is the maximum load this RF433 relay receiver can handle?
A: The module supports a maximum current of 10A at AC 85–240V. This makes it suitable for controlling LED lighting, incandescent bulbs, and other small electrical loads within this rating.
Q: How far away can I control the switch with the remote?
A: In open areas, the RF433 receiver has a wireless range of approximately 20 to 100 meters. Range may be reduced indoors due to walls and other obstructions.
Q: Can I use this module in countries with different voltage standards?
A: Yes. The module is designed to work with AC voltages from 85V to 240V at both 50Hz and 60Hz, making it broadly compatible with electrical standards across most countries.
