Sonoff - The $5 WiFi Smart Switch That's Compatible With Alexa And Google Home

In this video I show you how to setup the Sonoff WiFi Smart Switch. This is a $5 smart outlet that allows you to automate pretty much any appliance. I use it with my google home mini to turn on and off all the devices in my electronics lab.
This is NOT a sponsored video. I purchased everything you see with my own money. See FAQ #5 for links to where you can purchase your own Sonoff switch.
Thanks to the suggestion of many comments, I learned that the Sonoff Pow model will report power consumption! I've ordered some of these and I'm excited to start using them! Thanks for those who have pointed out this information!
FAQ:
1) Is this compatible with iOS (iPhone) devices?
Yes, the iOS eWeLink app can be found at itunes.apple.c...
2) Is this compatible with Amazon echo (Alexa)?
Yes, a tutorial can be found at www.itead.cc/b...
3) I have an extension cord/appliance that has three prongs (live, neutral, ground). How do I wire up the sonoff?
Any appliance or device that has a metal chassis needs the ground wire to be considered safe. Appliances that have plastic chassis are safe (in the US) with only live and neutral. If you need the ground wire, I would suggest getting the Sonoff Pow model which has three terminals to accommodate the ground wire. www.itead.cc/s....
4) I don't feel safe having to modify an extension cord. Is there a sonoff switch that I can just plug right into the wall and use?
Yes, it can be found here www.itead.cc/s...
5) Where can I buy these for less than $5 and how long does shipping take?
The Sonoff can be purchased from the manufacturer's website. The price before shipping (at the time of this video) is $4.85. I believe they ship from China which may take several weeks to arrive where you live. I ordered several that took about 2 weeks to arrive in the US.

[@NewAgeServerAlarm]

Dont leave all that copper exposed on your connections to the screw terminals on your sonoff. Make sure the insulation goes right up to the terminals to prevent it from arcing between the bare copper.

[@bytesizedengineering]

Thanks for the tip!

[@Time4Technology]

Shouldn't you use cable shoes (if that's the correct translation) for AC power wiring?

[@TheChipmunk2008]

Georg, not sure what you mean but I suspect you may mean the crimp on ferrules that turn the stranded conductors to one solid length? They're not commonly used in many countries. Most of continental Europe uses them, but the UK mostly doesn't (I however like them) and I don't think the USA does either. The terminals on a Sonoff switch are fitted with leaf springs so it can clamp properly on stranded wire :)

[@EL34XYZ]

Yes, always make the insulation butt right up against the terminal. And I also like to twist the wire and then add solder to make the wire ends solid

[@TheLawrencestewart25]

EL34XYZ never solder a mains wire if it gets hot the solder melts and the connection becomes dangerous

I don't have enough thumbs up to thank you for this! So the only "bad" thing is that it cannot be controlled outside the WiFi network

[@bytesizedengineering]

Thanks for watching! When you setup the sonoff with the eWeLink app you can control the switch from anywhere with an internet connection. You aren't limited to being on the same WiFi network.

[@NoGoodPig]

I use these to control devices from another state, even with a Google Home Mini in a hotel.

[@Ed19601]

yes you can. You can do it with the official app and firmware, but also after you flash yr own software on it

[@TheHavoc09]

Great so everything connected is vulnerable to hacking. Is there a way to run Wi-Fi mode only?

[@slowrabbit3242]

TheHavoc09 - there is even a better way as in having OpenHab server running let's say on a Raspberry and this is how you get "your own cloud" and control panel

[@pastudan]

Awesome video! $5 is incredible... I looked at sourcing everything and making my own PCB to do something similar, but the AC-DC power components would have been more than $5 alone. I do wish there was an app that doesn't look like it's from some 3rd party chinese company, but I guess the integration is what you pay for in the more expensive devices.

[@bytesizedengineering]

Yeah same here. The components would cost more than $5, plus PCB, plus enclosure etc. These are great! As for not using the chinese app/server, you can flash other firmware (Tasmota) which allows you to create a local server. Thanks for watching!

[@bskull3232]

Sonoff is open hardware, with an FTDI cable and a broken warranty label, you can tap inside and flash your own firmware (or some pre-made firmware from other developers).

[@hueypilot1950]

I wish I had seen this before I started my home automation. My one thought after trying 4 different switches is, it is simpler to use only one brand. Having 4 different brands means 4 different apps and different ways to integrate into Alexa. Thank You byte sized, I will have fun with a couple of these.

[@Omega-CMMS]

Excellent video...For safety reasons however, I would avoid using wifi switches to control blenders, or any sharp spinning rotating blade that can come into contact with your hand.

[@AB-nb2ic]

Or, just don't put you fingers near the blade when the jar is on the base (motor).

[@Ed19601]

Nice devices. The con is that you are using a third party server that relays via china. All works... until someone decides to pull the plug on that service. fortunately the SonOff can easily be reflashed with your own firmware. That also has the advantage that somewhere someone in China can't keep track anymore of when you use your blender

[@GuruDanny]

I am interested to see how to flash these. Any info/links would be very appreciated. Thanks.

[@bytesizedengineering]

That's true. I want to keep my blender use as confidential as possible! Do you have a recommendation on firmware that you like?

[@bytesizedengineering]

I'm going to experiment with flashing new firmware at some point in the near future.

[@Ed19601]

GuruDanny open it up. Solder in a header in the ftdi slot you find and program with a 3v3 ftdi TTL adapter straight from an Arduino ide. Make sure u do not plug it in the mains while programming

How exactly does it communicate? Does the app on your phone send a request to some online server which then relays it to the Sonoff switch? Or is it over your local WiFi with both your phone and the switch connected to the same wifi network (like ... a wifi printer, say)? Just curious.

Nice Video, I also do smart home stuff and hate the prices of the equipment, so what gauge wire can you fit in those terminals? they looked a little small for 12 gauge. Looks like it should work with alexa also.

[@bytesizedengineering]

12 gauge would probably be too big, but if you're device needs 12 gauge wire it probably draws more than the 10A current rating of the sonoff switch. They make other models that can accommodate larger wire and more current.

[@bobbyzilla]

What about an earth connection?

[@breakinn403]

Polarized appliances don't require an earth or ground wire. But if you were to control something that did need a ground then you would just hard wire it around the control unit.

[@gozharry7404]

Nice informative video But..... Not wishing to rain on anyone's parade but I didn't see any of the type approval labels one might expect to see on a relatively complex mains AC automation device. At least one or more of FCC, TUV, or CE (meaning the real one, not the false CE alternative 'China Export' label). Also the build standard and quality control inside looks awful. I would be seriously concerned over risk of carbon and/or dendrite tracking between high voltages between copper/solder elements, which is a different failure mode to arcing via ionised air. It's a common problem on poor pcb designs where low resistance paths develop over time and guess what? It gets hot. Without UL qualified materials it may catch fire while you are 20 miles away playing with your phone while your neighbours call the fire engines.......! Be safe. Use qualified components/materials or do the work yourself to verify that the design & build will satisfy your statutory regulations. If you don't care about this then use it in a garden shed which won't burn your house down when things go wrong, which they inevitably will.

I think there is a version with CE but these sonoff devices are all tuya based which means they all run over a other chinese company. They also can pretty easy be hacked during setup, which means that you can flash some custom firmware like tasmota.

They are also available in bare module in populated circuit board to be power by 5VDC, 7 to 32VDC and/or 240VAC. Basically all Sonoff switches are controlled by eWelink App. If you have an Amazon Alexa device which is controllable by the App of the same name eWelink is one of the registered skill inside. Thus if you activate the eWelink with Amazon Alexa App it will copy the Sonoff switches data across so that you can voice-control any of them.

great device , Thanks for sharing. I have been an Electrician for the past 22 years, so I want to make a suggestion.

The Sonoff are great! The Sonoff version that you have got a small problem though, they don't have support for earth line, as the bigger ones have. The Sonoff 10 version are better in that way. There are also versions where there are a power meter inside. And one with two relays in one. The firmware in them are not open source, but there are some people that managed to reprogram it. Easy to install, if you DO NOT HAVE AC POWER connected when you program it. You can fry your computers USB port (if you are lucky, if not your computer and yourself). Always do it on a cold system, without hot AC power connected, and you will be fine. When the new firmware is in it, just connect it as usual. I have stoped used the Chines web service and use the TASMOTA firmware. Then I can use the Sonoff without needing to have a working internet connection. Just my local WIFI LAN and my Mosquito MQTT server on my RPi.

It's worth noting for an extra $5.50 the pro model you listed in the description can show your how much current is being used via the App. According to their website the pro model also gives you "monthly energy consumption summaries via App".

Thanks for the tip!

[@jhyland87]

Very nice - Subscribed! Im just starting to get back into Arduino and RPi. Videos like this are useful

[@MrNigel1340]

Thank you, a very informative video, have just purchased the Google one and this information on the switches will tie in nicely, regards Doc Cox

[@bytesizedengineering]

Thanks for watching!

[@koruki]

I would like them to add a notification when power is lost. This would make it perfect for deep freezers

[@GilVazquez]

OMG this blow mi mind! I really want buy one of these! Thanks to made this video

[@satyamchourey6120]

Well it works in monitoring and real-time Applications as well . For that you need to have use both subscribe and publish segments of iOt . Will suggest Adafruit to manually design . Also you can use Google assistant on IFTTTT now a days.

[@cottondai]

Awesome tip brother. You gain a new subscriber.

[@cfvgd]

i just putted these in every sealing lamp. Easy. Now my bedroom lamp lights up just before my alarm. So i wake up easier. :)

[@lfcbpro]

thank you so much, didn't know they connected to google using the home assistant, cheers bud :)

[@rmhutchins7]

I enjoyed your video. It was very helpful. Thank you!

Great way to muck up your wifi band!

[@bytesizedengineering]

Are you talking about having lots of devices connected to my network? WiFi was designed from the beginning to support lots of devices on a single network. Also the sonoff devices use little to no bandwidth most of the time. I've seen no impact on the performance of my network.

[@philr2664]

I have tried these and Gosund SmartLife. Gosund does not make an in line switch , but the wall plug is a much better device. They are both very easy to set up, but the Sonoff is twice the size and depending on where the plug needs to be placed, can waste a wall socket. Also you can get Gosund on Amazon in two days. It took two weeks for Sonoff to arrive.

[@MarzNet256]

Great review! I am gonna try hard wiring this into some lighting circuits.

[@alexcomp99]

I just successfully wired a lamp in my entertainment room using one of my newly acquired Sonoff switches.I have some observations which I think will be useful to anyone contemplating ordering and using these switches.They are quite tiny and this could be a good thing if your intention is to insert them into an existing electrical box but it does create challenges. The insertion points for the wires are tiny, in fact the device itself is tiny. This means that there is no chance you would ever get standard 12/2 Romex wire connected to this device directly. Ceiling lights and standard switches will usually be wired with this 12 gauge wire. This means you will need to create an interface to this device where the 12 gauge wire is reduced to allow for connection. I'm looking into a good way to do this and have some thoughts but it can be a problem.Standard lamp cord is 14gauge sometimes 16gauge and can be inserted only just barely. The holes are tiny and the little bitty screws tightening the connection are also tiny. I just found inexpensive connector blocks that will easily connect 12g wire to smaller and is re-useable. If you're going to do a bunch of these switches and will need to interface larger gauge wire you really want these. Here's a link www.kinequip.com/wago-222-412-50-pk-compact-splicing-connector-2-conductor-terminal-block.html The way these switches are rated is puzzling to me. Voltage times amperage equals power so if they are rated to pass 10 A on 110 V circuit, that wattage would be approximately 1100 W. Yet the device itself is rated only 2200 W. I'm not sure why the discrepancy but would be very interested to understand what the real capacity of the switch is. I have smart plugs controlling nine amp pumps in my Koi pond and they are doing fine. I don't think I would want to try using these switches on such a heavy current draw even though they do say 10A. Would really like to have a better understanding of this. Any thoughts?

[@bytesizedengineering]

I agree that the power rating is confusing. I would suggest sticking to a 10A maximum load. The relay inside is rated at 10A and won't handle much more current than that. However the relay can switch loads from 90V-250V AC. Some countries like the US use 120V and (most) other countries use 240V. The relay is still limited to 10A regardless if you're switching a 120V or 240V load.

Thanks for sharing this, great video, very clear and good information!!

[@wolfgangzeisig6313]

thanks for keeping it simple

[@davidalanmedia]

Awesome tutorial, definitely going to give that a try.

[@bytesizedengineering]

Thanks David!

[@kopshopper]

Great video. Informative and a great idea to save money!

[@bytesizedengineering]

Thanks for watching!

[@JaredJanhsen]

LOLZ, your video triggered my Google home "Sorry I don't understand that."

[@bytesizedengineering]

whoops, sorry about that!

[@rice0009]

If you really want to play with Sonoff units, look into Tasmota. You can flash the Sonoff firmware so it doesn't have to be directly accessed by the Internet. BYW: Sonoff now makes units that can monitor the current being drawn by the devices connected to them.

[@FrancisLitanofficialJAPINOY]

Even the smart switch has multivoltage, please check your voltage appliances before plug it in. Step down transformer with smart switch can also useful.

[@matt4193]

Cool and nice! Enjoyable to watch, and very informative! I'll look forward to more content. Cheers

[@TheAgenTWorm]

Thanks for the video , Very cool ! I just bought one off eBay.

[@RichardBronosky]

If you think of this thing as a cheap WiFi enabled relay, you can find tons of uses for it. It can be used for anything where you need to press a button. You could use the relay to close the same contacts that signals your garage door to open/close. You could use the relay to close the contacts of a mute button on a $3 universal remote. Then instead of being angry that your Apple TV can't mute your TV, you can (with the help of IFTTT) say "Okay Google Mute the TV"

[@bytesizedengineering]

Those are great suggestions!

[@RichardBronosky]

Maybe you can do a video showing how to cut the mains traces going into the relay so that the relay can be used for closing other circuits. (I have a dozen coming but I am pretty terrible at finding the time to edit videos.) Great work, BTW!

[@JoeVinson]

I have some of these, but I thought they had a low max amperage? I suppose I should look again. I bought several and never have used them. Thanks for the video!

[@tbarkalial_saafy2594]

Man that's what I was looking for. 👌👌👌

[@captaindadpool7904]

This is awesome! I am going to try this out

[@davidwagner2626]

Good video! I'm not sure if you have looked lately but I saw a few different Sonoff Wifi switches with power consumption measurement on ebay.

[@bytesizedengineering]

Yeah, I've since learned about the sonoff pow model. It can measure power consumption. Thanks for the heads up though!

[@dranilsaxena]

Very nice explanation.
