4 Channel WiFi Momentary Inching Relay Self-Lock Switch Module,DIY WiFi Garage Door Controller (5-32V)

While this switch can be tricky to setup, perservering with it is worth the effort. It's not quite plug & play to setup and the auto-pairing mode did not always work, so I used the manual pairing which requires a few more steps using the App and worked well with different routers. I have purchased six of these switches to use in different projects and have discovered how versatile they are when using the IFTTT programming. The programming is not difficult (I'm not a programmer) and I have been able to program a channel on a switch to cause conditional actions on other channels on the same switch or to cause conditional actions on channels on other 4CH switches. The possibilities seem endless, but you need to invest the time to learn. Remote access to the switches I have installed over the past few months has been reliable and they have always come back on-line after power and Internet outages without needing to be re-paired with the router. This device is better than some other brand name products I have installed which sometimes need to be reset manually which annoyingly requires me to visit the remote location.

This was very easy to set up and was demonstrably working within minutes after downloading the eWeLink app. The device exposes four channels for controlling devices that require a contact closure to activate. My own garage door needs a pulse contact closure on one channel to open. It has a separate set of contacts that needs a pulse contact closure to close the door. This device has four contact channels that enables me to control two doors. The device offers a good range of capabilities allowing each channel to be configured to either pulse or switch or interlock and contacts are duplicated as normally on and normally off. ….. and all this for £17. Only one slight criticism is the documentation is a bit scant and best to print out the Amazon product notes and then everything is revealed.

When I bought it, Amazon warned me that this item has a high return rate. I also saw on various discussion groups that people complain it keeps turning off a second after you turn it on, which I couldn't understand either as it was happening to me. It is not mentioned in the documentation that the device has three modes, controlled by the mode switch. By default the device operates in pulse mode, so when you turn on a relay it pulses before turning off again. This is probably not what most folks would require! If you press the mode button, then it changes to static mode, meaning that when you turn on any of the four relays they stay on. This was what I wanted the device to do. If you press again then the device goes into interlock mode, turning on any one relay turns off all the others. Once I'd figured this out I was really happy with the device and recommend it as great value for money!

As per usual instructions are very lacking, but if you intend to use something like this then you should have an idea of what you are doing. Setup was very easy pairing to the Ewelink app. For my use it was to automate our electric recliner sofa. We are currently using inching mode set at about 9 seconds which sets the desired comfort level with one touch or by using alexa. All in all a great product would recommend it, need another one now to automate our vertical blinds.

Works well with garage doors and gates and very cost effective, and very easy operation with alexa .

This was super easy to set up and works perfectly. Garage doors begin opening the instant my voice command is completed. I can even say "Alexa, Open the pod bay doors" and all 4 begin opening at the same time. Thoroughly recommended.

This is a second unit to add on to my system been running now 24 hours a day for 3 years

Bought this to control two devices with Alexa. Works fine with all four channels separately through eweLink but if you use Alexa the commands it all of them only switch on or off channel 1. Meaning only one device can be set up with Alexa. This makes no sense it gives voice commands for each switch, but only fires against one. Setup was hard work it took five attempts for the pairing to recognize the device. But after successfully working getting it working with the phone and not connected to Alexa was not too difficult. Including setting inching settings. But as I only purchased this to add Voice activated commands to two devices it is useless unless I buy two one for each component. Also Amazon seems to have a version on prime for £12.99 where picture is exact duplicate of this one.

Je l'ai utilisé pour commander un portail. C'est parfait. Je l'ai même configuré avec GOOGLE HOME, et aucun problème. Très facile à configurer et à mettre en application. Que du bonheur.

I would pay 10x for something that actually worked perfect outside the box, from a US company and a better app/manual. But since it was under $15 I really did not mind getting more involved on the DIY side. I use this to open and close my commercial garage bay in my warehouse. Before, I had to use manual push buttons inside the door to operate. It's a 3 button system, Open (1 press opens door fully), Close (Need to press and HOLD to close), and STOP (emergency stop/used for when you don't want the door fully open). I setup relay one to click on for 1/2 second to activate the UP button. The second relay I set to inch for 18 seconds to close the door. The third relay I set to activate the STOP button- however this does not work as the STOP button seems to be wired in a different manner. I will update when I figure that out. 2 Things that I found difficult: 1- Initial connection was clunky. I do not like to allow location settings, but the app requires a precise location for initial wifi connection. After doing that I setup no problem. 2- The inching did NOT work at first. After several google searches, I found out that the "Mode" button needed to be pressed to activate this. I had to press it 2x to get the inching settings to work in the app. This I found totally pointless- why would you need me to press a physical button when the app allows you to set these times on your phone? It worked after doing this even after unplugging the unit a couple times. I was able to get this to work with Alexa no problem. So now, I can say "Hey Alexa- Open the Garage!" and my garage bay door opens right up. I have a camera facing the door just in case, and will install a wifi outlet to shut the relays off after business hours to reduce security risk. (ie, if a potential intruder shouts "Open the door" the relays would be totally powered off and would not respond). Another major plus- I have forgotten my keys before, and that means a trip home and wasted time. Now if that's the case, I can open the garage! And I can now drive my car right in to the warehouse on hot or rainy days without getting out of the car- provided I don't have too many pallets stacked up inside the door. Overall, it was a great solution to opening and closing a COMMERCIAL garage door. There are many, many ready to go options for RESIDENTIAL garage doors, but the commercial 3-button setups are sadly overlooked by most manufacturers.

Mit diesem 4-fach Wlan-Schalter steuere ich 24-V-Ventile zur Gartenberegnung. Das Gerät befindet sich seit 2 Jahren in einer wasserdichten Installationsdose sommers wie winters draußen. Ich hatte nie Netzprobleme damit.

Alles werkt prima. Ik weet alleen niet waarvoor ik het zal gebruiken. Gevolg van koopziek zijn.
