Review: Brilliant Kit…… - LightwaveRF has been around for a long time, love their kit and is very reliable! Just wish they would add a fuse spur to their range and also a basic socket and switch that doesn’t include the automated side as there are some places I want matching sockets and switches but can use the smart switch. Just want everything in my house to match… But a brilliant product!
Review: Fantastic SMART Home Lighting and Sockets - 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.

## Questions & Answers

**Q: If i just want one of these in my house do i need the hub to make it work with homekit?**
A: The (annoyingly expensive) NEEDS the Link Plus to work with anything smart, but if you want it as a dimmer switch, then they "work" solo - I'm actually removing mine as it overheats like a SOB and the lights occasionally turn on for a fraction of a second even when nothing has requested it...
If you want a brutally honest opinion, then AVOID THESE LIKE THE PLAGUE!!!

**Q: Does it work with samsung smarthings?**
A: Yes but only via the link plus module.

**Q: will it work as a 2 way switch (3 gang) with another switch that isn't the same (dumb 3 gang on/off)?**
A: I would probably wide them line in to this as switch with strippers from L1 and L2. Strappers into L1 and L2 of the 'dumb' switch and common out to ceiling rose or luminaire - simples!

If you're not sure about this, then perhaps best to get a sparky in to (gsi not diy) to comply with part P of the building regs.

**Q: Does this work with Hue ambient GU10s**
A: Not directly no, ie you can’t wire these directly to fittings with smart bulbs. However, if you have Apple HomeKit (using an iPad or Apple TV as a “Home Hub” and either (a) have  a neutral wire at the switch , or (b) buy a dimmer with an extra gang (eg 2 gang or more) with the first gang feeding regular bulbs, it is possible to use the dimmer as a remote control for Philips Hue bulbs (provided you have the Hue Bridge of course) or any other HomeKit compatible devices. However this is currently limited to on/off actions only, not dimming.

 The Hue bulbs should be on a lighting circuit that is always on ( not switched using a light switch) so should probably have a separate isolation switch somewhere. Then in the Apple Home app you add the Lightwave dimmer and Hue bulbs as accessories. Finally you would add some automations to link the two using the Lightwave dimmer as the “trigger” to turn the bulbs on and off. Sounds complicated, and it does require 3 “hubs” (Lightwave, Apple, Hue) but it provides huge flexibility.

If you want a simpler but less flexible option (ie only works with Hue bulbs), maybe look at the Friends of Hue wireless switches (Niko, etc).

### ⭐⭐⭐⭐⭐ Genuinely brilliant piece of kit
*by A***R on 28 May 2024*

Working on making my whole house smart and I needed great smart switches. These are brilliant I found compatible aurora bulbs dimmable there is a list of compatible bulbs . The light switch is easy to fit. I’ve also incorporated into my home assistant and it works great. Ofcourse these are definitely expensive so I can’t afford to do the rest of my house for quite some time but I think they work really well and I’ve actually had no issues with them at all. So as a brand these are brilliant, I mentioned to a friend also and he fitted his entire house with them too as he was renovating. For those geeks who want to kit out their home with smart lights these are a great buy and later I plan to also have sensors so lights come on and off as and when needed aswell . And I like the fact it’s a clickable button too.
