Frequently Asked Questions
Q: What app do I need to control this WiFi relay switch module remotely?
A: This WiFi relay switch module is compatible with the Yiweilian (Haoyi Micro Link) APP, available for download on iOS and Android. Once connected to your home Wi-Fi router or mobile hotspot, you can control the relay from virtually anywhere using the app.
Q: Does this module support both WiFi and 433MHz remote control simultaneously?
A: Yes! This module supports both Wi-Fi 2.4GHz app-based control and 433MHz RF remote control, giving you flexible control options — use the smartphone app for remote access or a 433MHz remote for hands-on local control.
Q: What is the difference between click mode and self-lock mode on this relay module?
A: In click (momentary) mode, the relay activates only while the command is triggered and returns to its default state immediately — ideal for doorbells or momentary switches. In self-lock (latching) mode, the relay stays in its switched state after each trigger, toggling on or off with each command — perfect for lights, locks, or appliances that need to remain on or off.
Q: What voltage range does this WiFi relay module support?
A: The module is available in two variants: a DC 5V model and a DC 7–32V model, covering a wide range of power supply options. The maximum load capacity is 2200W / 10A, suitable for most home automation and electronics applications.
