Zoenova Smart Switch 2.4GHz WiFi Smart Light Switch Compatible with Alexa and Google Home, APP Remote Control, Timing Function, Voice Control (No neutral Wire Needed) (NO Neutral Wire Needed, 2 Gang)

Found this so easy to fit Connected to the internet so quick and easy tooBut i wouldn't attempt fitting this unless you have some grasp on Electricity I'm a Plumber and found it easy to fit And looks amazing Little bit expensive But i love smart things

The smart switch has attractive features such as intelligent voice control, LCD showing time, temperature, network status, etc. The installation manual is clear and easy to follow. The product, however, has some limitations. A capacitor module (the unit at the bottom of the photo) needs to fit into the circuit to stop my LED lights from flicking. The manual says it is an optional unit, but I found that the switch will not be able to properly function unless the capacitor module is fitted. The problem is that there is no room to store the unit in the existing wall box. I have to replace it with a deep box. The design of the switch does not allow it to replace a two-switch combination typically used for staircase lights as it uses a common wire for L1, L2, and L3 (if fitted). For a price of £32.99, I expect a better design than this.

Disclaimer: I am not a qualified electrician. I am however a microelectronics engineer.On face value this looks like a really interesting product. Something that doesn't need conventual power to act as a smart light switch. However the deeper I looked into this, the more I became concerned.It's packaging is nice, and the information clear. This is a Wi-Fi controlled light switch with additional temperature, timer and physical buttons. It looks like it will swap out any existing light switch you have. So how does it work? Well it takes a very small amount of power that would normally go through the circuit and into the light (on the L1 circuit). It then has two relays for switching on L1 and L2 (and L3 if you have the three way version).There's a lot to say about this design. Firstly, it won't work on a typical staircase two-switch combination, because it uses a common wire for L1, L2 and L3 (if fitted). Secondly, while it looks like it would simply replace an existing double-switch, it won't as there's not enough room unless your wall box is extra deep. Fitting is also impacted by needing an optional capacitor module (included) to stop any LED lights from flickering (the instructions suggest this goes across your light fitting, rather than the switch). In fact, without it, the unit just powers off when a light is turned on. I was unable to turn that light off again with the switch if that capacity wasn't fitted.But its when I looked at the switches specification I began to become suspicious. No where on the packaging is a rating for current, despite it having a range of UKCA and CE marks. Digging deeper, the circuitry doesn't look like it has enough isolation for arcing, and runs its 5V circuitry very close to its 240V power. The relays are rated for 7A @ 277V, so in theory it should manage up to 1.9kW of power (i.e. large halogen lighting circuits), but I wouldn't trust it because of how close things are together. The Amazon listing says 10A, which even at 240V simply isn't true. There's also precious little space for heat dissipation, and I suspect this switch could easily overheat or burn out, beyond the basic electrical limitations. Electrolytic capacitors are known to age quicker when warm.I wanted this switch to be the answer for a connected home, but I don't think it is. The requirements on a relatively simple capacitor, dubious wiring isolation, and poor component management, coupled with a lack of amp rating labels, make me think the CE marks aren't genuine. The product seems unlikely to last a long time before component failure, and could be a genuine fire risk when installed in a wall.If you want to consider this product, I strong suggest getting the opinion of a qualified electrician, both for its suitability and installation.
