Review: Perfect Solution for sn old roller shutter - 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.
Review: Great device for controlling a motor/actuator via an App - 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 !

## Questions & Answers

**Q: Is there anyway to get it to reconnect to wifi? It seems if it loses the wifi connection for any reason it won't reconnect unless I power cycle it.**
A: Its reconnect automatically, maybe is the router/AP or wifi signal quality.

**Q: to reset my cable modem by removing power and let it come back on, can this unit complete a momentary cycle without internet connection?**
A: You must have wifi for this to work with Google or Amazon or Native app. With out internet or an application you just have a on/ off switch

**Q: once a momentary command issued over internet, can it complete if i remove the internet connection?**
A: If you remotely access it and send command once the command is received it will activate command.

**Q: Is there anyway to attach an external wifi antenna to this thing?**
A: it already has its own integrated wifi 
an additional antenna is not possible, its not designed for it

### ⭐⭐⭐⭐ Good, small, wifi switch - with caveats
*by R***S on 7 September 2021*

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 :)
