LNL WiFi Smart Light Switch, No Neutral Wire Required, Alexa Light Switches Remote Control, Voice Control and Timing Function, Compatible with Alexa, Google Assistant and IFTTT (3 Gang-Single L Wire）

You need to set aside at least an hour to install and set this up and you will need to understand wiring diagrams. You may well need to install a deeper pattress as the switch is very large, 30mm +. You will need to remove the ceiling rose and fit the capacitor, this bridges L1 and N and without installation light will flicker and possibly not work at all. The only problem I have is, it still will not connect to Alexa but given time, and a few choice words, I will no doubt resolve this. I'm happy....so far

The media could not be loaded.  The design looks nice and neat, the problem is with the functionality of the device. I have faced several times where the lights switched off and on again by itself as well i have faced some blinking when the lights are off as shown in the video. Also sometimes the lights will be stuck on and no mater what i do it will not switch off either manually or using the app, which i had to switch off the main room breaker and on again to restart them. Overall im thinking of replacing them with other smart switches.

This double switch worked perfectly. I needed to change the light switch back box as these switches are quite deep (33mm) so won't fit in a normal depth backbox but that's clear in the product description. I didn't need to install the capacitor as it worked straight out of the box. Set up Smart Life app easily and created routines in Alexa app to control the lights. I'm really pleased it was that easy.

Once you realise the space needed behind the unit it is easy to fit and works well with Alexa. I am also impressed with the look and quality. Would buy again should the need arise.

Looks good, feels good, Wi-Fi. But not easy to connect. Haven’t found out about longevity yet.

This switch is great. Ordered the wrong one first time, this one doesn't need a neutral. Nice and easy to install. Fitted into the standard mounting box. I'm controlling it via the TuyaSmart app and it works perfectly. Will be buying more

What isn't clear from the product title is the amount of other things you will need to do if you don't have a neutral. I know how to replace a light switch but I don't know how to install a capacitor or repurpose other wires safely. If you're thinking this will solve your setup of not having a neutral - think again.

I bought one of these (2 gang) to operate my hall light and an outside porch light. The first one started to play up during the first day, eventually simply becoming non functional a couple of hours later. I thought the capacitor may have been faulty, so I bought a second complete unit (with capacitor) but only installed the switch as the capacitor was not faulty. After a few hours, the breaker tripped and when I switched it back on, one of the switches was still working fine and the other one just leaves the light on, whether the switch is on or off. I literally can't switch the outside light off at all now. Hopeless. So,I've now ordered a two gang switch from another supplier. Both of these switches will be sent back for a refund.
