Lightwave LP21MK2 Smart Dimmer with Energy Monitoring, 1 Gang, Stainless Steel - Works with Alexa, Google Assistant, HomeKit. iOS & Android Compatible

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.

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.

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.

Ordered two switches which arrived promptly.First impressions were they looked stylish and modern just what I was looking for.Installation: simple enough but needed an electrician due to old school wiring, took him no time at all but gave me peace of mind of a job done properly.Functionality: well I’ll be honest this is where I was disappointed!Firstly the front plate has no apparent fastenings to the case therefore it is effectively balanced in place and prone to falling off despite rigerous attempts to secure it. Certainly not what you expect after paying £150 for 2 light switches!!The manual calibration works great to get the optimum light output but fails to provide a lower cut off, instead the lights merely switch off when dimmed to the ‘calibrated’ point.Alternative to hive or nest?Absolutely not !! The hub required for full functionality is laughable in price! £150 for a WiFi router is beyond a joke!£150 gets you a hive hub, thermostat and fitting and is often offered at £99 as was mine! You then add on the extras as you wish!Unlike Lightwave who come in at the top end of most sensible people’s budget for the bare foundations of a smart home so you can’t develop your own system for months or even years!This product will never be a rival to hive or nest until they review their frankly ridiculous pricing strategy!

Overall the best I’ve used, and the included app keeps getting better with more features. Buttons give a soft but firm click when pressed. They do wobble a little (not a bother to me). Integration with HomeKit is very easy. The customisable LED colours are a great touch. I’ve had mine for 4 years now and no issues to report.

Been quite reliable , easy to setup with Alexa . Mind you , this requires a pro hub to connect to WiFi . Without hub this is a standalone manually operated switch . But with Alexa the automation options are numerous .
