MHCOZY WIFI Wireless Smart Self-lock Momentary Interlock Relay Switch,DIY WIFI App Bluetooth Remote Garage Door Opener Controller

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.

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.

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 !

Bought this to replace a 4 channel switch which used the ewelink app which was limited to 8 timer functions but could be upgraded for a n annual subscription of around £10 so as I already had numerous switches on smartlife decided to find an alternative device , am using the to control garden sprinklers and a pond air pump which was limited with the other device to one operation a day as each on off was 2 timer events , this unit has a limit of 30 events which is a great improvement, the pairing operation was amazingly quick and seemed to be automatic with little interaction needed , have had to buy an enclosure , will have to see how this performs. Update seems to keep losing network connection but being less than 16 inches away from netgear wifi booster which manages to reach a camera 45 feet away I can only assume the unit is faulty , rather than sending back I will see if it is teething problems, update still has network problems but works all the same with the built in memory function so will keep as the connection comes back after short time and works ok .update still keeps losing network connection and needs to be turned off and on , so am returning back to amazon.

I am using this in my campervan to control lights and a heater for my lithium leisure battery. Has good range and uses the same phone app as my maxpeedingrods diesel heater which is based on the smart life app. Easy to set schedules and delays etc.It's a fantastic piece of kit and so cheap.

Set up is very easy, just open smartlife app and it configures itself seems to work seemesly.All names can be changed and customised.Lots of various timing functionsHighly recommended
