MHCOZY Updated WiFi Wireless Smart Switch Inching Self-locking Relay Module,Set Inching Time from 0.5 second to 1 Hour,be applied to access control,DIY WIFI Garage Door Opener (1CH Smart life app)

Having lost a fob to the garage door, I explored these wifi switches and I am so glad I did. 2 of these, total cost of just over £30, has now given me wifi control on my phone and it was easy once you identify the connectors you need to connect to (just one common and then the other 'Normally Open' connection to the relevant connector (up or down). Note, I needed 2 because my old garage door shutter (a 20 yr old elero) is controlled by a fob (no wall switch) but clearly it had to be switched somehow. I did explore the 'Meross' route but had a 'lazy' reply saying they couldn't confirm if their product would work. Having explored a bit further, I was convinced this would work and indeed it does perfectly. My type of roller shutter door has a connector strip numbered 10 through to 17, with 12 being the common, signalled by a continuous solid line underneath on the surface mounting, 13 to bring the door down, signalled by a 'switch' icon and 14 to lift the door up (signalled by another switch icon) all icons printed on the surface mount backing. The app was easy, just scanned the QR code and installed. I had no problem with needing to change router settings to 2.4ghz, it just worked first time for me. Set up both switches on the app, named one 'Door Open' and the other 'Door Close'. Changed the inching settings under the 'Timer' function to 2 seconds so the switch immediately turns off once activated, because on my old door the fob had just 2 buttons which needs the alternative button to be pressed to end the action of the first button. Finally put the wifi relays in a separate box under the current controls to prevent any issues by trying tocram in the relays to the original control box. So far so good, great value for money.

The item arrived in one of those card envelopes that fit through the letter box - there wasn’t any box, so I was half suspecting that this wouldn’t work. I wanted a switch to control an actuator / motor via an App, eg, turn the motor one way and then the other. Firstly, ignore the wiring diagram in this listing and draw your own, it’s easier. Once wired up, it worked first time. If it doesn’t work, press the ‘interlock switch’ in the circuit board once, this will solve the issue forever. You can control the motor (or whatever you have attached) via the micro switches in the board, however, installing the App is so quick and surprisingly very easy. It literally took 2 minutes to connect and using the App, I was surprised as these things can be fiddly. I’d definitely buy this again. Oh, don’t forget, this is a 4 channel device, so if like me you’re operating a motor, don’t forget you’re only using this to hall did it’s potential l as you’ve another 2 channels free. Happy project building !

I bought this to install inside my garage door opener specifically because this can not just turn on or off like a normal switch, but because you can specify the duration - meaning you can send a momentary 'push' of a button. And it works perfectly. It was simple to install, and easy to configure. The only catch and caveat is that it really struggled to connect to my wifi to start with because my router (like most routers nowadays) is dual band and 2.4ghz plus 5ghz. This device simply would not connect and I was really struggling. I ended up having to disable the 5ghz band on my router just to set this device up, and then re-enabling the 5ghz band once it was setup. Once done, the device connects every time to 2.4ghz but it was a bit of a faff to have to reconfigure my main house router just to get a device to connect in the first place. Going forward, if the makers could supply this in 5ghz also it would solve this niggly issue. Overall, I'm happy with the device and it works perfectly for what I got it - just be aware that setup might be tricky if you have dual band wifi :)

This was very easy to install and get working with HomeAssistant for use with my garage door. Great quality of build and working flawlessly. Once powered up it takes a matter of 3 or so seconds to connect to the WiFi and be ready to activate. Highly recommended if you are looking at this item. :)

Looks like I managed to connect in the end. I got it yesterday and set it up fine but today it could not connect to wifi anymore. It was because I set it up far away from the router where 2.4G was strong while today I moved it next to the router where 5G was stronger. So it got confused. I had to change the wifi name for 5G so it will not be picked up by mistake. I linked it to Google Home and all works fine so far.

So easy to install and it's connected to Google so can open on voice command. Setup the Chamberlain ML1000EV to automatically close after 30 seconds, so even if opened in error it will automatically shut. I have safety sensors installed at the base off the garage door which means by placing something in between them, I can leave the door open indefinitely if I need it open for longer. Edited: Device only works with eWelink (who charge a subscription to link with ITTT) meaning you cannot automatically opener the garage door based on your location (driving towards your house). Will still work via Google (or Alexia).

Was a pain to pair. Was about to give up. However eventually I got there and it works well.

I have a pair of recently installed electrically operated garage doors, which are operated by a 'bell push' type button. I have been looking for a smart switch which would provide a simple closed contact operation i.e., not one that passed mains electricity through it and would work with Amazon Alexa, this does both. You can adjust the duration of the 'contact close', which the device refers to as 'inching' from 1 second upwards, I use a 1 second duration, which works fine i.e., it closes the contact for 1 second then opens it again automatically. The instructions are simple to understand and it is quick and easy to pair with Alexa. You can use a standard 5 volt usb cable or a an open wire connection to any dc source between 7 and 32 volt. I use the Smart Life app to operate it as I already use the Smart Life app to operate other devices i.e., you don't need to download the Tuya smart app if you don't want to. I have nothing against the Tuya smart app, I simply didn't want another app on my phone. My only minor criticism and this is an Alexa criticism which is that it doesn't understand the instruction 'Open or Close' it only understand 'On' or 'Off', so the command is "Alexa Door 1 On" to open garage door one and "Alexa Door 1 On" to close the door.
