MHCOZY 4 Channel USB 5V AC 85-250V Smart WiFi Wireless Dry Contact Relay Switch Module,Tuya Smart Life app Remote Control,Compatible with Alexa Google Home

I purchased this in hopes of controlling different areas of low-voltage lighting independently in my backyard. Most transformers are single channel and the multis are crazy expensive. I previously had a smart plug in the transformer to link it with my other lighting. Wifi signal out to the transformer was always a challenge. This unit has no problem staying connected and reacts instantly to Smartlife triggers. The wire ports are a little small but handle 12awg wiring.

Using it for Halloween props, skeletons that you get that have the momentary display push button, actually cut off the momentary button and wired the 2 wires to the N/O contacts on this device. So i can program all the eyes/lights to go on and off with the rest of the Halloween lights/props on a time cycle.

Nice module. Works well with SmartLife App, but no IFTTT support.

This worked out perfectly, connected to my automatic gate opener for remote access. Now I can open my gate, and turn on the light above the gate, remotely.

All ok AS expected

I am using this for two linear actuators for hatches above the stairs to a loft area. I have used relays before for single actuators. Love that this can operate both and incorporates Alexa, wifi, and a RF remote when the network is down. I am waiting for a different power supply so that it can power both actuators at the same time but so far looking like just what I needed.

Anything that looks even close to this and says TUYA, is a A PIECE OF GARBAGE, the board has Bluetooth built in configured only for pairing so you can't just use as a Bluetooth relay like advertised, the app is in Taiwanese it takes 6 hours to pair and the relays are NOT 10 amps they barely handle 3 amps before welding shut. Just GARBAGE
