Smart WiFi LED dimmer switch module

Let me just start off by saying I’m a professional lighting control engineer, so I’m all too familiar with the flickering of LED’s when dimming them. I never usually leave reviews, but if this can be of help to anyone then it’s worth writing.I was looking for a smart dimmer for a new pendant chandelier in my house, something to integrate with the ecosystem of smart products I already have - but that could also have a physical switch station for the wife or guests.I first purchased a touch dimmer by another brand - which flickered and flashed anything I attached to it. I tested this with all manner of LED loads and load adapters and nothing settled it down, so back it went.That bad experience was replaced with this product, which I bench tested before installation. This managed to dim a single 7W squirrel cage LED lamp with a more than adequate range. Once connected to 3 of these7W lamps it’s dimming became even smoother.Installation does need a neutral, and some space. I got it into a 35mm pattress with minimal difficulty, but I did have the added height of over plaster which added another 5mm or so.Set up was also easy, the device goes straight into pairing mode when first powered. You need wifi AND Bluetooth on, which allows smart life to use its new auto finding function. The device popped up to be added without any searching or anything. Putting the device back into pairing mode requires a steady 5 pushes on the reset switch you have attached. If you are using a standard light switch / rocker switch, this translates to 10 switches. I think that may be where some people are getting confused.The type of switch this uses is a reset / non latching / retractive / press switch. Any of these terms will get you to the same thing. They are readily available at Screwfix ect as they are a standard item for doorbells or electric gate/ garage door contacts / press to exit door systems in the UK.All in all, a very impressive product for the money. I will be buying more of these.

Works brilliantly for controlling wall light with led dimmable bulbs. Flawless tuya and alexa integration.

Does what it claims well!

These little modules are great if you have the room to put them in the ceiling above a downlight, a ceiling rose may be harder as once you make a hole big enough to fit this in the ceiling you might struggle to refit your light fitting.I recently rewired my house and wired switch wires back to a central location as I knew I wanted to have a smart switch that would work along side my day to day switches. The fact that these switches know the status of the light is fantastic, for example if the light is on and you tell alexa to turn the light on it doesnt change anything and visa versa if it is off.Other devices don't know the status of the light, so if the light is on and you tell it to turn the light on it actually turns the light off, which is annoying, but this module has over come that by using the S1 input, it is always monitoring the status of the lights.Connecting to Alexa was really easy, I have loads of smart devices so my wifi is already set up to accept 2.4Ghz devices. If this is your first smart device you will want to watch a Youtube video to make sure you can set this up on your router first.Once you know that you can do that and you are confident you have the correct cables in place using the handy wiring diagram above, crack on and order one. I did, now I have two and am about to place another order for a further 6. This really makes all your normal lights smart. I just wish it could dim the lights as well.

Wired in correctly. Worked perfectly for about two days, then spontaneously exploded one morning!An electrolytic capacitor, part of the high voltage circuit, failed spectacularly, blowing the plastic case open (as I discovered when I extracted it from behind the momentary switch).Hopefully, just a one-off failure. Replaced with a two-gang version (one-gang was not in stock).The replacement has been working flawlessly since installing several weeks ago...

I managed to install this behind an existing light switch to all it to be Alexa controlled. It took probably an hour to install and works like a charm. Was a bit worried it might struggle to get a good WiFi signal in a metal box with a metal light switch in front of it - but doesn’t seem to have any issues.You do need probably 35mm depth to be able to fit behind a switch, but also depends how deep your switch is. Mine was 2 gang 2 way (single width ) in a new build house and it fit, just.Amazing way to add smarts to your house without being unsightly or complicated to use - the old switch still works fine!Update:Still working flawlessly. Have also purchased the dimmer version, which also works extremely well (requires a press switch rather than on/off switch) both manually and with Tuya/Alexa.

I had real challenges on getting a suitable smart switch - usual challenge, no neutral at existing switch, is it 2 way/3 way etc I chose this device as it was rated highly and was small. Installed to ceiling rose quickly, only issue was my existing wiring kept popping out of the terminals, which was not a problem with the device. All installed now and paired immediately. Great Product and will buy again.
