Wi-Fi Relay Module - Channel and Supply Options

Add app-controlled switching to a properly designed installation. This Tuya/Smart Life Wi-Fi relay board comes in one, two or four channels, with separate low-voltage and mains-supply versions.

✅ Control matched relay channels from the app - The compatible Wi-Fi setup lets you operate connected control circuits through Tuya or Smart Life.

✅ Make switching part of a timed routine - Supported scheduling and inching functions let the relay operate according to the configured timing.

✅ Add a separate handheld control option - The RF function accepts a compatible 433MHz learning-code remote when one is supplied separately.

Build the Control Around the Circuit

Choose the channel count around the functions that need separate control, then match the board supply to the selected version. These relays provide switched contacts rather than supplying an output voltage, so the connected circuit needs its own correctly designed arrangement.

The current board has no USB 5V input. Use the selected 7-32V or 85-250V supply version exactly as its markings and wiring diagram require, with a suitable enclosure and competent installation. This module does not provide the complete safety system for an automatic door or other moving machinery.
