Ewelink WiFi Relay Switch,Self-Locking/Momentary Timer WiFi Switch Module,Compatible with Alexa Google Assistant (2CH)

I got this unit to switch the fan settings on my house air recirculating system. It does the job perfectly. I fitted this in the loft near the unit and take the main supply from a local USB supply/power socket. I’m using it for the units 5VDC switching lines to override the fan boost switches around the house. I struggle to understand why anybody would use it for power applications such as AC light & power switching, when there are other more suited devices on the market, i.e wifi switches. This unit is a relay based switch, so might seem similar (and can indeed achieve the same result) but does not have any of the appropriate cabling/enclosure requirements for 240VAC, so seems dangerous to use it for such. The photos on some of these reviews with it mounted on a wall adjacent to a room light switch and exposed AC wiring looping into it is truly frightening.Instructions are non-existent, but setting up the Wifi link was easy enough once I found a YouTube video on it. EWeLink App and Alexa link up is great. Really very pleased it’s exactly what I needed for this application and has transformed the way I can set up the system. The board is nicely enclosed too, for not much more money than others without an enclosure, so saved me having to source that myself. It was literally fitted and working within one hour of delivery.

This switch is easy enough to use and relatively reliable. I'd be worried if/when the eWelink service went down as it would be dead weight but for now it's working.If you find that interlock can't be disabled through the app or web interface it's because you have to do it in hardware. The app will show it as disabled but it will still interlock. Togglng the interlock hardware button appears to solve this.4 stars as the software has bugs and because it's unclear if there is a solution to operating this without third party cloud services.Some housing would be nice too, even if it's an additional purchase!

Was easy enough to setup and use, has options for power supply from either USB or another DC supply, worked pretty well through the app and website and the timings can be adjusted from the app should you need more than a momentary relayMy only gripe is that the buttons on the circuit board are not labelled, so you have to refer to the included instruction leaflet if you need to use them, not an issue initially but if you lose that leaflet it could become an issue. Overall, a pretty solid product, can't fault it.

I replaced a single channel relay switch with this 2 channel one. Connection to my network was easy once I solved my own security issue. Initially I couldn't get the relay to self latch until I saw another reviewer's comment about some configurations needed to be done in the hardware. This turned out to be the MODE switch. It now controls lights and a water pump (all powered by solar) to schedule and the relay switch is power by the USB input (5V) from the solar controller.

Followed instructions several times and could not get it to work, so returned it.

I bought a cheaper version of a Wi-Fi 4-Channel Board (a review of that is available elsewhere).I was 'Disappointed' with that design.On the strength of previous reviews here, I bought one of these 4-channel 7-32V devices to try, before buying enough to cover the additional 20 channels of control that we need.And I'm mighty glad that I did eventually buy this one!I need 16 channels of 'momentary signal' Normally Open outputs, to address some PLC Inputs, ranging in 'On' time of between 0.5 and 3 seconds.And a further one Normally Open Output to be programmed to close and then open every 1 second for 8 'pulses' in a 'Scene'.PROS:Very easy and intuitive to set-up.Firmware update was transparent - and didn't affect functionality.Each relay can be 'manually energised' by a physical push-button, accessible from the front facia. (= a useful 'Test' function!)Once wired-in, there is no need to remove the top cover: Changing 'Modes' (Inching / Latching / etc) are 100% accessible via eWeLink, and are stored 'on-board' the device.Good Wi-Fi range - this works even where my mobile 'phone shows virtually no Wi-Fi signal.A nice mix of Status (Blue) and Relay Energised (Red) LEDs on the board.This accepted the +24VDC Power that runs all of my other Garden Automation (PLCs / Dusk-To Dawn sensors, etc).This ignores the 5G being transmitted by our BT Router without having to turn it off.This 'Remembers' its settings (Modes etc) even when the power to it has been interrupted for a while (hours, so far).Seemingly, there aren't any 'Global Mode' issues: In 'eWeLink' it is possible to set each channel to 'Inching' or 'Latching', and the accuracy / response time(s) of the 'On->Off Inching' times is pretty-much 'Stopwatch' accurate.With this device, the above-mentioned 8-pulse 'scene' works like a dream(!)There is absolutely no relay 'chatter' or variable random on-off timing issues, irrespective of the 'mode' set for each channel.It comes in its own 'protective' Plastic Case, relatively easily wall-mountable.CONS:Access to the terminals is only possible when the device has been dismantled.Dismantling this device requires the removal of four screws, from the rear of the device.Ergo, if you decide to change the hard-wiring to / from the device, you will need to remove it from e.g. the wall.So, allow enough cable / wire 'slack' in your install, to enable this to be possible!BOTTOM LINE:After 'trialling' one of these devices, I've ordered a further four...!I will have to 'modify' the top-covers (e.g. drilling holes) to allow access for a thin 'Terminal Screwdriver' blade......so that I don't need to remove it from its 'wall-mounting' if I wish to re-wire.I understand that this design needs to shroud the 'potential' of LV for CE /Safety purposes.But as I'm only going to be running ELV (+24VDC or 12VAC) through these terminals, there will be no issues.Other than that, this piece of kit is AWESOME!Thanks for reading.*EDIT* One of the four units which I eventually bought, failed:I described the fault to the Supplier, who - after some additional testing / re-setting - agreed that the unit was U/S.A simple return to Amazon and a replacement sent / installed, and all has now been hunky dory for over one year.Wish that I could say the same about the eWeLink 'software' though.......I'm still having to run a one+-year old version, owing to the newer version(s) not being compatible with older Android installs...

This is incredibly fiddly to wire up, the screws to hold the case together are on the back and the circuit board is held in with them, so essentially you're wiring up a loose circuit board. The instructions aren't great and I initially assumed the common was hard wired but quickly realised I wasn't getting an output!Picture is with just one output wired in, I've since used junction boxes for the positive and negative.However, once it's done, it works brilliantly and does exactly what I wanted. I have it wired to a 12v solar controller to operate lights and an irrigation system. It has physical buttons so I can turn on the garage lights like a regular switch, the outdoor lights via Alexa and have an irrigation system set up on a timer.Great value and works really well, knocked a star off because of the fiddly wiring.

Istallazione semplice e prodotto perfetto!

Funziona alla grande, utilizzato per comandare due zone irrigazione ed i lampioni esterni tramite Hassio

Das Modul funktioniert besser als erwartet muss ich ehrlich zugeben, auch der Preis ist meiner Meinung nach völlig OKIch betreibe damit meine Dieselstandheizung im Garten und kann diese jetzt bequem von zuhause aus starten.Aber eine Frage habe ich dennoch an jemanden der sich mit Technik besser auskennt als ichKann ich das Modul auch mit einem Netzteil betreiben welches eine Ausgangsleistung von 12V 30A liefert ???Wäre super nett wenn mir das einer beantworten könnte
