4 Channel Smart WiFi RF Bluetooth Wireless Dry Contact Relay Switch Module,Phone app Remote Control,Compatible with Alexa Google Home (Tuya 4CH 5V AC/DC7-32V)

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!

I see in the description that Amazon states this is a "Frequently returned item". I suspect that a lot of the returns are that people don't really understand the device. For me, it is EXACTLY what I wanted. I need a WiFi switch that I can control my gate operator and garage doors remotely. This is GREAT for that purpose. I connected each of my garage doors to one of the 4 relays. I put the two wires from each to the "COM" and "NO" connections. I then set the control to "INCHING" for each and the inching time to one second. Now when I hit the app for one of the doors, the relay closes for one second then reopens. Just like hitting the button on the garage wall! As far as the review about it not being a "true latching" relay, I easily solved that by supplying power to this controller from the Uninterruptable Power Supply that I already had in the garage. Now it never loses power, so the relay always stays where I want them.

I run my drip irrigation with this. Few 12 volt water solenoids, some outdoor cabling, and the standard 1/4” poly tubing. Ended up being a whole lot cheaper than the 4 channel irrigation timer and I can control it from my phone. I’ll have to put it in a weather resistant enclosure of some variety, but it’s currently stuck to the bottom of a solar panel with the $10 charge controller that’s been out there for 3 years now. I have a second one that’s lived in the utility cabinet so I can control the water pump, the water heater, and a dump load that’s been going for quite a while too. Connects to wifi easy, easy to set up timers, and the relays on the board haven’t given up on me yet.

Well built. Paired with app without issue - Chinese characters aside. I purchased this to have a bluetooth backup for my garage door in the event the network was down (I have a Tesla so it automatically opens/closes the garage door via the MyQ device I installed years ago). DO NOT pair this with the Smart Life app - as when you can only use Bluetooth it does not work. The unit beeps instead of activating any relay. Use the Tuya app - it works properly. Note that in both apps, when you don't have internet - the naming of the device and buttons can't be downloaded from the server - so it shows default text.

I have two installed but replaced them several times already. When it works it works great. The WiFi part however is a weak part. The WiFi control is why I purchased this product. Not sure why it breaks down so easy. The Bluetooth keeps working fine and you can still use it manual but that’s not why I install it. If I find another similar product I would try that and hope the WiFi keeps working.

Device is easy to connect to your router using WiFi. Download the app and you can program on off times or operate any switch from anywhere in the word with your smartphone. You will need a very small straight edge screwdriver to tighten the screws for the wire connectors. You have a choice of normally closed or normally open Contacts? The instructions indicate that you can use Bluetooth but I left that off. The photos above show two screens from my smart phone one shows programming for switch one, and the other shows the four switches with the soft buttons to turn them either on or off. You can also rename the switches.

I use this to control contactors that switch off and on my electric patio heaters. Unit performs as advertised and was easy to integrate. The only issue is that occasionally the unit will lose connectivity and I have to power cycle it (flip the circuit breaker that provides power).

Works great for controlling devices with Alexa!

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.

Il est petit et s'intègre vraiment bien... Fonctionne parfaitement ,pour une ouverture de Garage et Portail. Installation rapide via Smart Life . C'est nickel je recommande .

MHCOZY 4 Channel Smart - Excellent switch that works well with Alexa. Four switches that can be controlled separately. Tuya App works great and connects it well. Instructions that are provided with switch are very basic, but Tuya App gets it sorted - took a bit of scrolling through Tuya App to get it right - but I got there and I am just a very basic novice, ie this is my first zigbee device.

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.
