Easy to connect to wifi. - 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.

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! ## Frequently Bought Together - MHCOZY Tuya Smart Life app Dry Contact WiFi Relay Switch Module,1 Channel DC 12/24V AC 100-240V,Compatible with Alexa Google Home - Shelly Plus 1 UL | WiFi Smart Relay Switch with Dry Contacts | Home Automation | Bluetooth Gateway | Alexa, SmartThings & Google Home Compatible | No Hub | DIY Remote Control | Garage Door Opener --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/555349506-tuya-smart-life-app-dry-contact-wifi-relay-switch-module](https://www.desertcart.tn/products/555349506-tuya-smart-life-app-dry-contact-wifi-relay-switch-module) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-02*
