Cheapest it's been for a while. Very easy to wire and a cheap way to make your devices 'smart'.

I picked a few of these up on eBay a couple months back. They're fiddly to wire, they don't accommodate an earth, and since Christmas they're very unreliable. Up until December they worked around 80% of the time. I don't know if it's because too many people bought these for new echo devices received at Christmas, but they rarely work now. They're fiddly at the best of times. Even with the wires soldered in, using 2 core wire, and a 5amp fuse in the plug, I won't leave one switched on at the wall when I leave the house. Before I was weary of them because of the cheap Chinese build; now that combined with the fact that they rarely work and their own app often fails to find them, I'm sticking with my tp-link smart plugs. Yes, these are a LOT cheaper than the tp-link (usually £6 on eBay). And up until recently they worked surprisingly well (if you could manage to wire them up). But like I say, physically shaky tech combined with massively unreliable software...I guess you get what you pay for. I prefer to shell out for a tp-link and feel more comfortable leaving them switched on at the socket when I leave the house. No disrespect to op, thank you for posting the deal, I just wanted to offer my experience with this product.

Amazing all the electrical deals I have been looking at lately

I keep hoping the S20 sockets come back down to about this price again, I got a bunch last time but want to get some more, I could replace some of my devices with these at a push.

One thing I have been desperately looking for to no avail is a Wi-fi controlled dimmer. Slowly replacing all my 433Mhz stuff with Sonoff and need a Wi-fi dimmer for my terrarium...

You just kinda...cram the earth off to the side. I replaced all mine with 2 core wire, I also soldered the wires in, and I still don't really trust them.

Why don't you get the Sonoff RF bridge, around £7, and will control up to 16 433MHz devices I believe, as well as sense 433 PIR and Door sensors.

And if you want to get rid of all your 433 devices, send them my way, I'm going to add them when I get my RF Bridge.
it doesn't appear to have a CE mark on the device, so whilst it may be safe, it's not legal to sell (imported) electrical devices in the EU without it (worst case if there was a problem your insurance wouldn't pay out).
These are quite good for devices which don't require an earth, eg lamps.
I got 3 of them last Sept when they were £2.30-ish each.

If you get the larger ones, they are earthed and allow a higher ampage, and will also monitor the power usage.
I spliced mine into a mains extension, everything still fused.

The good thing is that you are encouraged to hack them to allow local netowrk access, eg from Home Assistant or Domoticz.

I won't use cloud based services such as Alexa.
If you want local voice control, try Snips or Mycroft.

I got laughed at the the last time I posted these (although that was probably because I suggested them as a DIY option over a NEST device). They can be bought for about the same from the official site ($4.85), although they charge P&P which makes them more expensive than this...
Heat added btw.
I know this is HotUKdeals, however I thought it worth mentioning that these are really easy to integrate with Alexa (Echo dot)! That YouTube video is an example of how to wire it up dangerously - it's best to put these things in a project box if they are going to be exposed - yes it'll double the cost, but it adds an extra level of safety, especially if the mains lead gets pulled out!

Try this YouTube video on how to do it safely...

I already have a 433Mhz bridge - hence having a ton of them already.
It’s a Telldus Live, but of late has become terribly unreliable with their servers going down.
Sure I could DIY my own 433Mhz sender, but biggest drawback is only 1 way comms, so no guarantee that triggering the device over 433Mhz actually did anything. Sonoff I have 2-way comms and state in my Home Automation is always correct if triggered from source external to my HA system.

The information is on their web site. It might be worth noting if are going to use these in your own projects you should consider reflashing - especially given the news about the server outage.

Agree, did not even plug mine in without flashing new firmware to use MQTT instead, but this is going to be daunting for majority that just want a plug which works with Alexa!

I don’t trust anything designed / manufactured out of China that is Internet connected! Or many other places for that matter until I sniff what it does!

And the Sonoff Bridge can be configured for local-network Home Assistant too can't it?
So your 433 devices are 2-way comms then? What about the Energenie Raspberry board 2?

I'm only going to set up dumb devices in the greenhouse, but also need to start reading my 433 and 868 weather stations.
Eventually my raspberry pi would like to look like a Homey amazon.co.uk/Ath…DDP

I’ve not come across any 433Mhz switches/dimmers which are 2-way comms. They all just receive some encoded signal and react to it. They are OK, but as I say no guarantee they are in that state for a wider Home Automation system. It’s done me well for 4 years, but now Wi-fi ones are cheap I’m gradually switching them out.

Tasmota and home assistant, these things are great. What's often overlooked is you can multipurpose them with the gpio. I have one that controls the shed light but also has a sensor attached to record the outside temperature and warn the missus if she needs a coat, one on a table lamp in the lounge also has a light sensor so I can set my sunset automations for when it actually gets darker. These are only limited by your imagination.
Sonoff servers in Europe have with been hit with DoS attacks and have been down. They are working on a fix. Follow ewelink and itead on facebook for updates. I have 7 sonoff devices and love them they worked perfectly until the last few weeks. I will be eagerly awaiting a server fix. For earth wiring you can use a junction box, put sonoff inside and just use a block connector to join the earth from plug side to the appliance side. I wouldn't exceed 8amps with these or around 2Kw though as its about as much as they handle. When they are working they are more instantaneous than wemo.
Not at the bloody minute it doesn't! Hope they get sorted soon. My smart home is dumb!

When I wired mine I bought a trailing socket and got an old kettle lead and spliced the switch into the lead keeping the earth wire unbroken, and fitted the trailing socket to the end, Maybe not the most elegant solution but it did the job. If I see it around i'll take a picture.

There’s a guy on YouTube whose overloaded one of these well over the 10a load.
these ones are meant to used in an enclosure.

If it’s not working, crack it open, solder on a header and flash something like tasmota on it.

I received a Sonoff Dual last week and it is CE marked.

Of course it's never worked owing to ewelink server problems

Is it an official CE mark or a China Export Mark
Is there a zwave equivalent of these?
Looks like a LV light transformer.
Dreadful devices tbh weak terminals, dreadful registration process and constant server issues.

You either find a way of running an earth around the switch or you buy the three wire model.

Flashed these work perfectly with Smartthings. I use them to power my cameras which are two wire only anyway.
Have some heat.

Have you got wall switches, I have ordered one awaiting delivery keen to learn from your experience
16A version has a earth terminal
Edited by: "cigbunt" 6th Jan
Have just fitted two of these to control my landing and hallway lights, flashed with tasmota so I could use with the original wall switches.

I started buying 433 rf wall switches, but I don’t like how they look and wanted the original look.

They are quite a pain to wire up, I enclosed mine inside a 2g back box with cable clamps and fitted a blanking cover over the top.

Don’t bother with EWeLink or the stock firmware it’s crap, I control mine with alexa using node-red on pi 3, they work great!
