## Customer Reviews

### ⭐⭐⭐⭐⭐ It works. Easy to connect to wifi.
*by K***A on April 12, 2024*

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

works, cheap, and easy to install

### ⭐⭐⭐⭐ Nice little DIY module
*by B***T on June 5, 2024*

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!
