Brilliant, if you get stuck the UK support center is great. Don’t need a neutral wire, works perfectly with alexa and you can set up switches to work together without rewiring the house! I’ve kitted out the whole house now

I’ve since started installing quite a few of these throughout my home. Pretty easy installation, power off and switch the cables over. Noticed the recess wasn’t big enough so installed the enclosed spacer looks really good fitted actually. Works really well.
Tech support was brilliant when I had a query with automation, talked me through everything step by step and even checked it was done correctly. Absolutely brilliant.
Highly recommended!!

I’m very impressed with this technology to the point where I’ve now put LightwaveRF light switches in every room of my home and have started to change some of the basic electric sockets to LightwaveRF. I’ve been using the system for a number of years and they have have worked perfectly. It works seamlessly with my Google Home setup, where I have a NEST Hub Max in each of the main rooms. The setup is easy and there are fairly regular firmware updates. The app is easy to use, but to be honest I only ever use that to set up the devices and routines, I use Google assistant to control them either from my phone or the Google Home devices. I prefer LightwaveRF over some of the other systems as you can use your existing lights and light bulbs, in most use cases there is no need to change, which means you have access to far more variety of light fittings, than say a Phillips Hue system. You do need to also purchase a Link Plus device, which is the router that connects the devices to the internet. but you only need one of these per home for all of the devices. I have a fairly large home and it hasn’t failed to reach every switch.
I can’t recommend the system enough.

I have installed two of these.
One operating with a neutral is perfectly silent, and offers energy monitoring.
One operating without a neutral works perfectly fine, however a slight capacitor whine noise is audible when you are next to it, and energy monitoring is not available.

The smart functions work flawlessly with Google assistant, however the buttons feel a bit flimsy for the price.

I initially bought one of these as my room. Was being decorated

Ended up buying three as the dimmer was easy to install and can be controlled with your phone or voice via Siri or Google..

I will be buying more as I upgrade the house

Easy to install well written instructions. Did have an issue with one side of the switch would switch off and on but the lights remained on, thought it was a faulty switch so managed to get a replacement (great service) fitted the new one and still had the same issue. Wish I had checked bulb compatibility as this proved the problem, basically I had two lights circuit controlled by the 2gang switch when you swapped the wires around you still had the same problem. I found it worked fine if you have a combined load of over 10 Watts so I used dimmable led bulbs @ 7w each. Very pleased with it. The whole system with the link plus was easy to setup and works great with the echo. Dot.

Use the correct bulbs

I have been using the Lightwave switches for more than a year now in my Apple HomeKit environment and their performance has been rock solid. The connection has not dropped even once. The app allows to customise a lot of features including changing the colour and intensity of the LEDs. I have also been able to use them as multi-way switches for my hallway lights which have three switches controlling the lights. They require a hub attached to your router which is a downside.

We have a number of these installed and they work well. Ours are linked to Google assistant enabling us to control our lights by voice. Only negative we have found is that if the switch is controlling a single bulb it can struggle with certain bulb types if the electrical resistance is too low. This can cause the light switch to reset itself and need recalibrating. Solution is to find a suitable bulb or get your electrician to add resistance in the circuit.

It’s as far as I’m aware the only smart dimmer switch available that you don’t need to use a neutral wire for.
Installation is easy and the the switch reports it’s status back to the hub.
Auto calibration is a bit hit and miss but easily adjust using the app.
I get on with it perfect. All that said it is a very expensive system.

Good quality, works well but ensure you read the entire manual – we have one set of lights controlled by switches in two locations (either side of a room) and hadn’t realised that we had to replace BOTH switches with Lightwave ones.

Great product, easy to set up and use…. Works very well with Google home… I tried a few cheaper products out before this one and had so many problems. Lovely switches, I have already re purchased.

Thanks

I was worried this would be the most complex switch to install. Turns out it was actually very simple and I found it the easiest to install. That could be down to me leaving this to the lady and having learned from my previous installs.

This was the white metal switch and I love it. Looks amazing on the wall and with the LED’s set at the dimmest level it’s unobtrusive in the room.

Easy to install, good looking for the home.
Setting up was a little frustrating if changing dimmable lamps, turning the power off and on from the fuse box and pressing the required within 5 seconds takes two people. Has some nice new features.

A little fiddly to get 2 way switching setup but once it’s working it’s brilliant and seems to work with all good quality dimmable LED bulbs. I’ve got almost 15 of these in various guises and am very happy

If you purchase a Lightwave L21 from Amazon and it is faulty. The Lightwave Technical Support Team are very good in replacing it with a new Lightwave Dimmer Switch. Excellant serivce and guidance. Would recommend as they have a solution to all problems.

I live in a rented flat and the light fittings are sealed units with 15 spot lights in four zones in the lounge. Replacing all of these with Hue or other smart bulbs wasn’t an option for me. After a little too-ing and fro-ing with tech support to figure out the wiring diagram against the standard UK home wiring setup (it’s not quite as logical as you’d imagine but makes sense once explained) to a complete novice, I now have 4 zone smart lighting I can dim from anywhere. I’m using the LightwaveRF (autocorrect is on form today!) hub as well. I’ve hooked these up via Google home so I can use voice control. My LEDS aren’t supposed to work with this type of dimmer and flickered during initial setup but some fine tuning of the top and bottom end of the dimming range has cured this.

If you just want a route into smart lighting and can’t replace every bulb or live in a rented place you want to easily remove the switch from when you leave this is a great produc

I have bought the LightwaveRF Gen2 light switches, sockets and a Link Plus. No problems setting the devices up, good quality products with a nice design. So far all works happily with the app.

Purchased with a few more items of the Lightwave products.
I am an electrician though and found the install very easy.
Used with remote switches and the hub it can easily be controlled.
Only issue I have with this item is the cost.
I had to two way my set of switches so required two units.
That’s costly. Also you require a supply to this so it can work.
Beauty is though a standard switch can be swapped for this and made into a 3 Gang.
Great product..

Looks great and works great providing you use compatible bulbs, specifically if you are like the rest of the population moving to Led’s. Need to check that your leds are compatible as there are more that are not than those that are. Check the lightwave website first…

Easy to fit, even easier to setup. No need to change how you normally use a light switch, so guests and family don’t need instruction on how to “use” your house when visiting.

I’m surprised, given the mixed reviews, but this works exactly as described and worked first time. I’ve just ordered another three for other rooms.
Setup was painless, I just followed the 4 steps in the poster it arrives with.
I chose this to replace our Philips Hue as having multiple light switches in each room was confusing for the family, and a limited choice of expensive bulbs wasn’t ideal.
Very happy with Lightwave as an alternative – its much simpler for everyone to use and seems to work with our existing regular bulbs just fine. 10/10.

Great switch, only one I have found for use in the UK without neutral wires. Works great with HomeKit. If I’m being fussy, the buttons could feel better when pressed, but quite robust and works well. Saves buying lots of smart bulbs that require switches to be left on.

I did get flickering lights from one of the switches, although a simple firmware update on the app fixed the issue and not seen it since.

Excellent easily installed product, a surprisingly small profile inside the box, the lightwave app works really well but the killer feature is the compatibility with HomeKit, with this switch you can turn any dumb light into a smart light, I even cut the plugs off of some floor standing uplighters and attached this switch to a pattress box, then wired the uplights through this, giving control from anywhere in the world with full dimming control of any lights in the house.

The only automatable dimmer I could find that does not require a neutral connection. Simple to wire and using the supplied spacer allows it to be used with a shallow wall box. I even used the spacer on a deep wall box as I think it looks nicer.
The only down side is it doesn’t support remote controls or integrate with other automation systems easily although it does support IFTTT and Alexa.
Having the two way communications does mean I can easily see if a light is on using the App but I wonder if I should have gone with the Generation 1 version as it has wider third party support and remotes.
Hopefully in time LightWaveRF will provide an API to support third party integration and extend the range but time will tell.

Beautiful design, simple(ish) to install, unless you’re trying to fit a 2-way switch which Lightwave convenient doesn’t mention in BOLD that if you wire it like you would a normal switch you would irreparably damage it, but luckily I realised before attempting to do so. The wiring symbols are also completely different to conventional UK light switch diagrams, would be great if there was some comparable guidelines for wiring. Something simple like: COM = L, L1 = X, L2 = S. There, I saved them the trouble! Very responsive control from the app though, but the hub is enormous and hangs off the router like a tumor. The metal buttons on the switch itself feel a little loose too. Just missing out on the 5th star due to the lack of examples for various wiring setups (e.g. 2-way, UK standard symbols etc) given the cost.

A very solidly built two button smart switch. Simple to use either smartly or locally via the buttons (tab either button to turn on/off or push and hold a button to adjust dimming).

If you’re going into a backbox with much less than 35mm you will need the spacer. It’s a great finish but does make the switch protrude a little – it doesn’t bother me but if you want a flat-against-the-wall switch make sure that backbox has plenty of room.

The instructions for fitting in the box are good for the electrical size of things and the warnings on how to wire and not to wire. Getting the switch to sit in the spacer and “snap” all four corners of the chrome front plate into place was a sodding nightmare, and eventually took two of us to apply a ton of pressure all around (and the handle end of a screwdriver behind a cloth) to get the last damn corner in. This was despite having removed and checked out alignment, flatness against the wall/spacer and so forth.

Once it’s on, looks really does look great and that finish is solid and polished – I’m really happy with it.

Pairing with the hub is easy (although in my hub setup originally Alexa couldn’t find the switch until multiple hub resets and calls to LW support – but that’s a hub issue not a switch issue), and if their is a pairing problem it’s easy to reset them (although that instruction isn’t in the box – if you need more info there’s various docs on the LW website)

The only slight niggle I’ve noticed is that when at the switch you tap the down button to turn it off, the light flicks off, comes back a bit and flicks off. I’m using Phillips bulbs, and there are many posts from Gen 1 that talk about the need to use good quality bulbs – so bear that in mind. Turning on the light however, no issues at all.

I’ve not put one in a bedroom yet, but be warned that the blue LED on the light between the button goes red when it’s off, and stays red whilst it’s off. It’s not hugely bright, but in a pitch black bedroom, may annoy folks that are light sensitive.
