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

I powered this from a 12v battery and it works great. The rf control works, but I use it via WiFi via the Tuya app and home assistant. I can’t vouch for the current rating of the relays as they only switch low current LEDs and larger relay for the main current switching. But so far so good. I would buy again.

I used this to control lighting in conjunction with home assistant. I do not trust this type of equipment to switch 240V so it currently is switching 24V contactors which deal with the mains lighting. Easy to pair to the familiar Tuya app and works great with home assistant. I'm sure you can reflash this if you really want local access but I have found this to be rock solid as it comes.

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

Works well in the Tuya app but for some reason which I can't work out, the instant you put the fourth channel on, no matter what sequence used to switch on (1-2-3-4) (4-3-2-1) (3-1-4-2) you get my drift. They stay on for about a second then all turn off. Even if using the manual on buttons. Any sequence of 1, 2, or 3 channels they will stay on until switched off. Put any 4th channel on and off they all go. ????

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 😉😎😎

Got this to remotely control my gate. Works great.

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

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.

As expected- ALL OK!!

I purchased this product to integrate into my pool pump to make it so that I can control from my phone. This device was very easy to set up and integrated it into the Smart Life app without any problems. I have it in a plastic waterproof container outside and have no connection issues to my Wi-Fi, even though the router is inside. Once to it. The quality is great and the product can be used for so many different applications. Automating a pool pump was so easy with this. After getting it working with the Smart Life app, I then integrated it into home assistant where I set up my schedule for automation. Couldn't be happier with this purchase!

Ürünü sipariş ettikten 1 hafta sonra elime ulaştı henıuz denemedim fakat ürün gösterildiği gibi .

Conexión vía WiFi a la APP Tuya rápida y sencilla. Lo alimento con un cargador de móvil. Acordaros que este modelo no se puede alimentar directamente a corriente de 230 v. Lo tengo en funcionamiento con 3 fases activas, 2 fases con 2 termostatos que encienden y apagan el quemador de la caldera de gas oil y 1 fase que enciende y apaga la caldera que es de gas oil. Funciona muy bien.

Parfait en parallèle du contacteur clef pour un volet de piscine. Je précise que la piscine est visible depuis la commande alexa. La tension d'entrée du moteur est de 24v ce qui convient bien (directement sur le + et - moteur), ensuite un des relais NO temporisé au temps de fermeture de la piscine + qq sec, et un autre relais NO à 2 sec pour l'ouverture. Perso je l'ai deporté via un 5 fils (24v+, 24v-, NO ouverture, NO fermeture, et COM) et mis dans une boite etanche plus proche du wifi. Reconnu dans smart life et alexa instantanément, je recommande. Garder le contacteur clef en cas de souci et bien élaborer scenarios et temporisation, sinon la clef ne fonctionnera plus (scenarios : la fermeture doit éteindre l'ouverture et inversement en cas de pepin + temporisation : le relais doit s'arreter une fois la piscine ouverte ou fermée).
