Smart Dimmer Switch 1 Gang 1 Way,WiFi Dimmer Switch Compatible with Alexa and Google Home,500W Smart Light Switch Black with Smart Life APP Control and Timing Function (Neutral Wire Need)

Couple of points :Firstly if you're not electrically skilled please seek advice before installing this.Secondly I see this time and time again - if you do not have a neutral wire terminated in your light switch this switch will not work !Thirdly the switch itself is fairly deep and you may need a spacer around the switch if you cannot replace the back box.I already had a Wifi dimmer light switch which works really well with Alexa and the Smart Life app. I hadnt tried this brand before and generally expectations of stuff like this is that they can be difficult to set up and instructions are poor - not so here all worked like a dream.Installed 2 switches in my Daughters redecorated room. First one was 1 gang 1 way replacement for a single way switch. Straight forward wire swap and connect to neutral. Powered up and switch worked ok with touch on and off. Then pressed and held for 3 secs and red light blinks, opened smart life app and connected to 2.4 Ghz WiFi network (doesn't work on 5 Ghz). Smart life app found the switch immediately and asked for my WiFi password. It was connected within less than a minute. I got a notification on my phone from the Alexa app saying a new device had been set up in Smart Life (nice !). I could work the device immediately from Alexa but I went in to change the name of the device.I set up the second device in the same way but this was slightly more complicated electrically because it was a 2 way switch. This is where novices should seek help (or watch you tube but I didnt say that !) I identified the live supply and the switched live to the light . I then discarded all the 2 way switching wires by coiling them up in the switch box. I then connected the neutral. With so much wiring the back of the box, depth was limited and I ordered a 10mm spacer to space the light switch off the wall. Set up was then as simple as for the previous unit.These switches operate 2 banks of down lighters in the same room. from 2 locations. Once set up in the app I was then able to group them into a room and gave the room a name (lets just say Fred). I could then say to Alexa turn Freds room lights on or off and it would operate both. I could also say turn on light one or turn on light two to switch the banks on individually. My daughter is very pleased with her new lights and bluetooth speakers in the ceiling which also connect to Alexa - all from Amazon :-)

Was easy to install, looks great and connects to alexa/smart life super easy

The instructions were not clear regarding the metal plate fitment. The back unit for the wiring goes through the metal plate first from the front of the plate. The rear of the plate has the "CE" and "RoHS" logo on the corner. Then do the wiring.When fixing to the back box, ensure the top edge of the metal plate is above the back box recess so the front glass plate can clip on properly.Only with the glass plate attached does it start flashing for the WiFi connection.Remember, if your WiFi name is shared for both 2.4Ghz and 5Ghz bands then you need to switch off 5Ghz temporarily so this device can connect to 2.4Ghz. Once connected you should be able to turn 5Ghz back on and unit should still function.I use separate Wifi names for 2.4Ghz and 5 so was easier to connect.I used the Smart Life app. Whilst the leds on the unit were flashing rapidly, the Smart life app found the new device automatically. You can try adding it manually if it does not find it by itself.As my Smartlife app was already linked to my Alexa account, Alexa then found this device automatically too.I prefer to use the Alexa app for device automations such as turning this devices switch for a light to come on automatically at dusk and turn it off at specific time.

Smart looking switch easily installed and easily connected to the Smart Life App. Both Google Home and Amazon'a Alexa picked up the switch via linking with Smart Life.The switch easily fitted into a 35mm back box. It needs both a live & neutral wire to power itself, as well as obviously the switched live going out to the lights. A lot of switches only have live & the switched-live and are lacking a neutral wire.My LED lights are fully dimmable and have worked fine with a manual dimmer for years, but this dimmer switch completely fails to dim the lights and the bulbs start to strobe/flash brightly rather than dim.Reading the reviews it appears that it works well for many, but quite a few report flashing lights. I'm unsure if the problem is faulty switch or some incompatibility with the dimmerable bulbs.

Excellent quality. Easy to install. Earthing required. Works well with dimming LED e14 bulbs.

Doest work

This looks great on the wall and we have even added an alexa switch to it so it can be used via that. However, it won't dim the lights....now I do think this is a light problem, not the switch, as we used a different switch and that's the same. Its about the power needed for the lights, mine are so low, no switch can go that low.I am thinking of swapping the lights, but not yet.m
