Tuya Smart Life app Dry Contact WiFi Relay Switch Module,1 Channel DC 12/24V AC 100-240V,Compatible with Alexa Google Home

Tiny, runs on 115vac, paired up first time with wifi using Bluetooth as well. I’m planning on using it to replace one of the switches in a 3 way switch setup for outdoor lights so I can control them as I arrive at night. Bench testing indicates setting “Remember last status” to OFF and “Switch Type” to RESET allows a push button switch to turn it on or off and the app does the same thing. No instructions on how to get to these settings. Touching the picture of the switch then settlings gets you there. My switch box happens to have 115v & neutral in it. Check before you buy. If there are 2 switches in your box, the other one may have these. It also behaves itself during power interruptions. Just close the app and re-open it to get it to synch with the relay. More later.

works, cheap, and easy to install

I have a lot of projects where I've used Arduino Nanos and relays for USB control of different devices, but I've been slowly migrating to things I can tell Alexa to do for me! I also have quite a few Wi-Fi smart switches based on the Tuya platform and have generally been happy with the capabilities and performance of their cloud based interface. Thus, when I saw this, I just had to grab it for my next project. To be honest, I haven't actually found its final application, so I can't comment on how long it will last, etc. but I don't have any reason to be skeptical on its overall performance. I think some of those one star reviews I saw were just people not knowing what they were doing. One of the pitfalls of DIY/hobby applications!

This switch was easily integrated into Alexa and was simple to wire into the remote leads for my gas fireplace. Nothing as nice as just saying "alexa fireplace on" or "off"

This works great! Even has some features we did not expect. Ordering another today!!

Like needs a fan, kinda hot. Totally defeats the purpose.

Great when it works but after a couple hours it drops off network. I then have to reset it to get it accessible again.

This works well and I like how small this is however with a tight or full switch box, you will have trouble fitting this in the box. Also, you are forced to use stinger wires with this, it's typically not a bad thing however, if you don't have extra wire lying around it becomes inconvenient. The only thing I do not like which is why I removed 1 star is how this makes a noise when you turn on or off through the app. It makes a single beep and it's kinda loud for me. This connects with the Smart Life app perfectly and through the Tuya integration or the Local Tuya app in Home Assistant. It works perfectly with no issues.

funciona correctamente y no he tenido que instalar una aplicación ya que tenía Smart Life y lo ha reconocido nada mas abrirla en mi movil, de momento satisface mis necesidades para activar un pequeño motor remotamente.

Fonctionne parfaitement,simple a mettre en place , utiliser pour commander un portail automatique

Ottimo relè wifi utilizzabile con applicazione SMT Life o Tuya, gestibile con Alexa. Non ha solo il comando da app o tramite Alexa, ma ha la possibilità di collegarsi a pulsanti fisici dell'impianto elettrico per essere comandato. Il relè è alimentato da corrente 220v ed ha un supporto per barra Din (quella dei quadri elettrici), e le istruzioni che lo corredano spiegano come fare i collegamenti sia per alimentare impianti 220v (massimo 5 ampere) oppure contatti puliti e basso voltaggio. Alla sua inizializzazione parte come relè bistabile, ed è possibile impostare se quando torna la corrente dopo un black out parte da acceso o spento. È possibile però impostare la funzione inching che lo temporizza a 1 secondo, comodo per comandi di apertura come cancelli. Riassumendo è facile da installare, è corredato da istruzioni dettagliate, è piccolissimo (ideale dentro le 503) e funziona bene. Lo consiglio

Funktioniert bis jetzt gut, bin gespannt wie lange

Great item small easy to connect works great
