MHCOZY4 Channel Smart WiFi RF Bluetooth Wireless Dry Contact Relay Switch Module,Tuya Smart life app Remote Control,Work with Alexa Google Home

I was sceptical about these but they work perfectly! The App is a little clunky but easy to set up, works anywhere. I’m activating 230v mains devices and 12v DC . Many a prank to be made 😉😎😎

easy to pair with the tuya app (no hub needed) - would recommend

Got this to remotely control my gate. Works great.

This is used on an off grid setup.Most of the time there is only the 12v circuit there (power banks occasionally).So being able to switch on the led lights until the mains circuits are live is handy, lights on when leaving, more handy, and having routines so that you can have a PIR trigger the light coming on, in the dark (settings I'm the app)) makes this really handy.So the setup is a WiFi router that has 4G cellular and powered by 12v.This uses SmartLife so easy to add routines etc

Dodgy cheap Songle relays make it a timebomb waiting to happen. These shouldn't be sold or heavily recommended not to use at 240VAC. Plenty of reviews for Songle relays online saying they break, melt and are a fire hazard.Fine for low voltage, but that's it. Also don't use the 5VDC input, they tend to just smoke and melt.
