You do NOT need a neutral wire in your switch for this to work. (Most UK homes do not have neutral wires in the light switches)

I got one and work brilliantly. Quickly paired with Google Home and also can set up scenes.

NOTE: The anti-flicker is required to connect.

Single Live Wire Design, Easy to Install

No need to rewire, directly replace your old wall switch

SONOFF T4EU1C is a 1 gang single live wire EU Wi-Fi smart wall touch switch that doesn’t require a neutral wire, being installed easily without rewiring your existing wire. It is compatible with tungsten, LED and CFL lamps. The unique toughened glass panel is heavily-duty enough so that it still keeps a new and clean outlook after being used frequently for a long time.






The LED backlight comes with a weak brightness based on the previous versions, which you will not be disturbed but quickly locate the switch at night. Designed with touch buttons which are tested repeatedly to ensure a superior sensitivity and make the switch always respond to your every touch quickly. App remote control support to manage home appliances to turn on or off at random where you are, making a lighted home ready to welcome to you when you come back home at dusk. The kitchen light is still on after a meal but you are immersed into the movies and don’t want to leave the sofa, simple to talk to the connected Alexa and Google Home, it will turn off the light instantly once listen to your commend.






Timing schedule is an absolutely decent choice at the moment you need to turn on devices in advance, or just forget turning off. Set a scene for your devices in your home, and tap the on/off icon once on the scene mode to turn on or off single devices or all devices of the entire home, no need to operate over and over again on APP. Plus, share the device with your family to grant the control ability to them directly, simplifying the pairing and adding steps. LAN control allows you to control connected devices even though there is no internet in your home. Struggle to recall whether you turn off light when on the go, just find the answer on sync status, on or off, know instantly.

Good for you. Now for those of us that were not so forward thinking or can't do that their now appears to be a solution. Good for us.

As a qualified electrician over 25 yrs , I wouldn't personally buy anything electrical from ali Express or likewise china, have experienced cheap and dangerous chargers and lamps/leds that are not to uk standard.
I have not used or reviewed this product and is my honest and open opinion.
I have bought products in the past and find it superior quality for the uk consumer. That sometimes is at a reduced 12v DC or 5v DC product.
This product is required to be installed at a 230V Ac mains at your home and I would warn anyone to be wary of the consequences of any failure in this type of product. My opinion.

I believe dimmers that do not require neutral are available as well (perhaps not from Sonoff, but who cares?)

Yes the switch.
And there's only 2 at my lights.
Clever idea but for me don't need this in my life yet

Have a look at the lightwave range. They do no neutral dimmers but bit pricey.

I was trying to soften the blow.
Just check before you buy you need a minimum 35mm deep back box for these.

I've just added some more switches to mine after initial setup and you have to unlink or re connect ewelink to Google Home, then setup your rooms again in Google, easy if you have a couple of devices in ewelink but if you have loads it's annoying.
Can you use one of these on a two switch circuit (e.g. one at the bottom of the stairs and a standard switch at the top)?
Does anyone know if it's now standard practice include a neutral wire available behind the light switch on new builds? I just opened up three of my light switches and they all have a neutral available in a choc block connector!?

Majority of the UK new built houses will have neutral at the light switch. If there's a neutral at the switch, you will have lot of options in the market.
This is for most of us not having a neutral to the light switch.

Not sure that's the answer to the question I asked. I have a light switch at the bottom of my stairs and one at the top. I want to know if I can replace one of the switches with one of these.

This is brilliant. Just what the market needs, as most UK houses don't have neutral at the switch.

Any 2 gang options? Most of my rooms have 2 or more switches. But great post. How have sonoff managed to do it without neutral and no hub?

I am also waiting for 2 gang, hopefully soon. 🤞

Beauty of this is you don't need a hub. And also the dirt cheap price for a smart switch.
miffyl11/02/2020 21:29

I haven't seen any. You are looking for a 2 way switch, which can be mistaken for a 2 gang switch. 2 way has 1 switch and not obvious and 2 gang have 2 visible switches on them and are commonly available. 2 way, not so common.

Yes it’s called feed at the switch. Its not only to make the capability of Wi-fi switches etc but also make life easier for the electrician not having to do the work at the ceiling level

So how does this work without neutral and a hub? Thought it wasn't possible? That you needed a hub if no neutral at the switch. Not complaining, just interested.
This model is highly likely to share the same code as the other switches in their range which means it will be compatible with espurna if you fancy removing the Chinese firmware from the device

I've been buying Sonoff devices since the original Basic switch and have a tonne of them around the house, but not a single one runs the stock firmware - not because I'm massively paranoid about the Chinese infiltrating my network (I mean, it'd be pretty boring if they did) but because espurna and similar custom firmwares offer more flexibility when integrating with other home automation technologies (such as out of the box Domoticz and Home Assistant support as well as MQTT and a native API).

EDIT: Oh and I ordered one (£10.80 using Revolut) so will hack the shiz out of it when it arrives.

How do these work with smart bulbs? Do they cut off power to them if "switched off" so no longer being accessible from the relevant apps?

I agree with you and judging by the comments on here - NOTHING - should be done on mains electricity without being "competent" (does not necessarily mean professional) I believe that is the law and people would find themselves in horrendous problems with insurance if anything serious goes wrong - fire etc or maybe worse.

Generally speaking if you have to ask questions on how to do it - you or not competent.

Looks like this is a 2 gang with no hub and no neutral required. Bit more pricey though but I might give it a go. I'd expect to be able to find it cheaper elsewhere.

I'd be interested to see the standby power consumption of this. I guess it must be quite high.

No it's not. It's a capacitor with around 0.33 uF. It has negligible power consumption.

Is it definitely based on the same chipset? I use custom firmware too but lately itead have been making a wider variety of devices eg zigbee which are not esp8266 chipset. A WiFi no neutral switch would have to be a very low consumption design so possible they would have to change the SoC.

Would like to know also, maybe it leaks some power to earth?
For those looking for alternatives, I've had better than decent success with the Xaiomi/Aqara ZigBee switches. No neutral versions exist but being ZigBee, they require some kind of hub, but for those of you using HA/hassio you can use zigbee2mqtt to deal with that part (which could possibly also eliminate your other ZB/hue/ST hubs if you want).

No hub. Connects directly to the app through wifi. Then you can get google/alexa to control it.
