WiFi Wireless Smart Self-Lock Momentary Interlock Relay Switch,DIY WiFi App Bluetooth Remote Garage Door Opener Controller (4ch)

Easy setup and reliable so far. Integrates well with Google Home.

I have an AC unit in my garage and loft. The thermostat has been in the loft. I had to go up and down the stairs whenever I wanted to change the settings. When I had the house built I did have the builder run a control wire from the AC unit to the lower wall in the garage. So with this wifi switch I was able to run the wiring from both thermostats, and from the AV unit to switch, for the control to the thermostat I wanted.The needed APP works OK. Only issue is when you select all on or off then the individual switches are displayed (nice) then you have to hit the OK before you can make another selection. You actually can name each switch, but have not yet found how to change the name (or add a name) to the ALL switches. I would like to name the "All On" to lower Control etc.

This review is for the MHCOZY Updated WiFi wireless unit.Not that difficult to set up, the eWeLink app is easy to use, and this thing is tiny. Neither of mine would pair with the default mode, but worked perfectly with the alternate pairing method used by the eWeLink app. My recommendation: if Pairing times out twice, just go straight to the alternative pairing mode (using the device as a wi-fi network). It will save you time and frustration.One thing worth mentioning... if you’re having difficulty setting it up on your Alexa, just use IFTTT and then link it to your Alexa as a routine. Super simple and seems to be more consistent.I have two of them, one for the driveway gate and one for the garage door. No problems with either. The gate control is soldered to an extra remote and the garage door is attached directly to the overhead unit. I have inching mode set at 1 second for both.This is so nice because I can set up a scheduled routine for opening and closing, or trigger either remotely.

This thing is awesome. I originally had a hard time connecting it to Wifi with the app, instructions were correct, but it just wouldn't connect. After doing it 2 or 3 times, it finally worked and I was excited to then install it for my garage door. Wiring it up was literally the easiest thing. I added more wire to my original garage door button that went in to the wire terminals on the side of it and now my garage door can be opened with Alexa and with an app on my phone anywhere in the world. I might also wire 5v to it from the garage door button itself. I would have to bust out my digital multimeter to see if it's outputting enough power so I can ditch the USB-Micro and have it tucked away behind the original button.The Micro USB cable I used (Not included) came from a Raspberry Pi Zero W kit I bought on Amazon as well and it has a switch on it for power On and Off so if I'm going away for awhile or if I'm worried something is going wrong with it, I can just turn it off at the power source instead of having to disassemble everything.I might buy more of these for small projects around the house. If you're on the fence with buying this because you aren't sure if you'll be able to understand the electronics, it's unbelievably easy and I even had my daughter put the wires in and screw the terminal clamp down.

Had a bit anxiety when I received the product since I didn't know how all of this worked. The manual was concise but enough. I used the Smart Life app instead of Tuya since I've already got an account. Everything worked out and now I can voice control the heater loop in my house. How nice..

They put DIY but they put crappy Tuya firmware on it. There is a USB port on the device but its ONLY for power. If I wanted to use the cloud to control my thermostat I would of gotten an beautiful Ecobee. You have to solder wires for a flasher to flash Tasmota and am waiting for that to arrive I will follow up but as it stands its not really worth the price. My board is a CB3S and you need use CEN pin 3 to ground to pin 9 turned on first and pin 15 UART1_RXD and pin 16 UART1_TXD an power 3.3v is pin 8.Update got the flasher was unable to flash tasmota maybe I am an idiot or Windows 11 ended up ripping a bunch of pads trying to get the device off the board to try to flash it maybe I can salvage part of the board with the relays but main and maybe just cut half of the board off with the other logic. Such a shame this board doesn't offer a direct ability to flash it since it has a USB port on it...

Bought this for a project I created for a video doorbell that didn't support my original/standard chime out of the box. It does require some DIY tinkering, but afterwards it works great for connecting to my original chime! For the DIYers out there this relay device (at the time of writing) does come with a PSF-B01 wifi module, which makes it compatible with Tasmota/ESPHome. Also just in case anyone was wondering, mine did come in a nice little plastic housing case, as well as a 4-button keychain remote (battery not included). Anyways, this has been well worth the purchase price, and very deserving of a positive review!

yes, easy to connect

Excelente lo utilicé para controlar la puerta de garage de mi casa y todo al 100

Made a 120v AC block heater controller for car with this awesome little device. Was confused about how the Bluetooth/ wifi worked, so here it is….Once device is linked to your wifi you can control it from anywhere in the world (if it is connected to your home wifi network). You can also use it without any wifi by using Bluetooth capabilities in its Bluetooth range with your phone. This device is working flawlessly through 3 walls of house and across yard to back alley (about 65-70 feet from router to device. Will definitely buy more of these for future automation projects 👍

Comes pre flashed with a software compatible with Tuyasmart. I haven’t done any extensive testing yet, but it has 4 pins to activate the relay via a 5v signal. Makes it easy to integrate into an Arduino or an rPi.I’ve used this to make a traffic light functional in my garage with the plan of integrating it into a parking sensor. Great product

Ottimo, funziona bene sia con wifi che con telecomando 433, alimentazione sia 220V che microusb. Morsetti non particolarmente capienti, diciamo che il filo massimo può essere da 0,75 mmq, più che sufficiente per l'utilizzo classico.

Funciona muito bem, com a aplicação Tuya, que também é muito boa, estou muito contente.
