A lot of functionality for little money
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. â¦.. 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.

Very Versatile Programmable 4CH Switch
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.

Ok, but set up can be tricky
Can be tricky to set up. Can’t seem to disable interlocking / inching with app eWelink. Can do it with the buttons, then eventually get it to work. Shame it doesn’t work with smartlife app.

Before you return this item
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!

Mature product; works great and bought a second one; for programmers: has WEB API etc.
Once set up its trouble-free.For the computer programmers amongst us, there is a full API online.One of my better purchases and very happy with it.Usual problems with instructions – photo doesn’t match the product and non-sensical / bad English.

Alexa would only work on one channel
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.

Très bon produit, à voir dans le temps.La carte se connecte sans problème sur une box livebox avec un répétiteur wifi.Le câblage n’est pas compliqué, il y a 4 relais (contacts) sur cette carte, permettant donc de contrôler 4 appareils.Pour du portail, ou porte de garage, il suffit de mettre 2 fils sortant d’un relais (Normalement Ouvert) vers le boitier gérant l’ouverture du portail (pour l’emplacement exact, voir le câblage du boitier en question).Si pas de place, mettre les 2 fils en parallèle de ceux existant qui commande en temps normal.Pour ma part, j’ouvre mon portail, et mon garage avec soit l’application Ewelink, soit depuis la voix avec google home, ou depuis ma montre connecté et ça c’est fort;)TOP!

I was a bit concerned it wouldnt work after reading some of the reviews, however it worked fine when hooked up to DC, just ensure the polarity is correct as it likely doesnt have any protection if wired incorrectly. I tested using 12v and 24v DC and both work fine. Setup on Home Assistant via HACS Sonoff plugin, was pretty straight foward to setup. Installed the app initially to get it connected to WiFi and set a static IP in the router, the Sonoff HACS intergration pulls the local address and communications is locally rather than via the web.
