I have my son controlling all the appliances in my home. I just tell him when I want an appliance on or off and he does it. Simple!

If you really wanted an authentic experience, you could rename your son. "Hey Google, turn off the living room lamp!"

[@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

[@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.

[@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

[@Ed19601]

byte sized many people use tasmota software (on github). I prefer github.com/computourist

[@slowrabbit3242]

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?

[@bytesizedengineering]

Thanks! That is very kind! I put a lot of effort into making my videos, and it's always great to hear feedback like yours. I'm still learning and trying to improve so any tips are greatly appreciated.

[@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).

[@someonefar5600]

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.

[@bytesizedengineering]

The switch connects to a server over wifi.

[@hotsauce7362]

What if you don't have your phone with you... and just want to use the blender...? Is there like a reset manual on off switch to this sonoff?

[@bytesizedengineering]

There is a small button on the sonoff switch that turns it on and off, independently of the app.

[@DaniloMajhenic]

and also independently of internet connection.

[@HOWDOI]

so the normal power button will n longer work???

[@wildonemeister]

Correct.

[@darrellcollins877]

great device , Thanks for sharing. I have been an Electrician for the past 22 years, so I want to make a suggestion. The device is rated for 10 amps, so you need to use a chord that is rated for that amount of amps. The extension chords like you show probably isnt rated for 10 amps. size 18awg wire is rated for 10 amps, for an extra bit of safety edge I would use nothing less than 16 awg wire on this device.

[@bytesizedengineering]

Thanks for the helpful feedback and doing it in such a respectful way! You'd be amazed how how many comments are just plain disrespectful! I believe the cable is 16AWG, but I'll double check. I'm not connecting anything that draws more than a couple of amps anyway. Thanks for watching!

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).

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.

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.

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.

I have tried these and Gosund SmartLife. Gosund does not make an in line switch , but the wall plug is a much better device.

It took two weeks for Sonoff to arrive.

Quick question... When you energize the switch, what is the default state? Does it automatically turn off? Or automatically turn on? Basically if I used sonoff to turn off the light in the basement, would I need to fumble around with my phone the next time I'm down there or could I just power cycle the wall switch to turn the light back on?

Thanks for the video. Is there a way for this switch to connect directly to a Raspbery Pi? I mean if I have one central application on a mobile phone that connects to a Raspbery Pi for home automation, can I integrate this switch within this system?

Great thanks a lot!! After watching this I had to have So quickly set about clicking away And through your links I'm now $81.80 for an 8 pack poorer But hey can't wait.

[@bytesizedengineering]

Hopefully they work out for you. They're $4.85 ea on itead's website.

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.

Nice job on that! How would you wire it if you're like me and live in Australia with a 3 pin plug and 240v? Are those switches suitable for 240v devices?

[@Geebax2]

Just go out and buy a switch made for australian conditions, like TP-Link, from Bunnings

[@olmianhcaoln]

Thank you your simple but detailed explanation about the neutral was great

[@bytesizedengineering]

Thanks

So was the blender plugged into the wall or the extension cord?

[@pvv1171]

Hey ! Can you try to use it with air-conditioner? thanks

[@skybesky]

Hi mate. Do you know if I could us it for controling something that use power bank to work? If not, do you know anything that I could use instead?

[@marcoserat3610]

Use the switch to control a relay that can handle the power that whatever you wanna connect it to requires

[@dakdur1126]

Can this be used with Apple HomeKit Also can this be used direct in line of the power cord of the item rather than running an extension cord for each and every item?, this would be significantly cheaper than buying 25 Wemo Outlets but I don’t want to buy this and extension cords for everything, especially when cords I currently am dealing with are already too long

[@bigtom388]

I was thinking of getting a couple of these, only question i have is do you have to use a extension cord or can i splice it into the cord coming right off the lamp

[@gsuccidesign]

Awesome! Question: how would I use the app without having to log in? There is no technical reason why i should not be able to control the switch with no internet connection, but just using wifi... You know, privacy...

[@woofinu]

Great job. Does this switch work with 220V?

[@hutchyx1]

Can it run in parallel in a wall cavity or does it have to run in series? also is there a thermal protection on the device?

[@PTTY100]

Very simple productive idea, do you have any idea about electric consumption by using that device !! Does it keep light current through the connected machines?

[@Yggdrasil42]

No, it breaks the connection via the built-in relay. Of course the device itself uses a bit of power for the Wifi and chip, but that shouldn't be much.

[@alanlarsen4191]

Loved your video - thanks! Do you know of a smart switch that will work with low voltage? I want to switch 24VAC on and off...

[@GurinderSingh]

Is both of device connected same wi fi routers I say can I connect my mobile directly to switch without any third wi fi support

[@MapleSyrup9181]

You're awesome. Got my Sub. I just got interested in home automation and about to pull the trigger on an Alexa Echo 3rd Gen, then starting looking at smart plugs and they are at the lowest about $8.75 ea and that is because it is Cyber Monday week. I"m sure they'll go back up so this is no brainEr. I'll be watching your channel as I can see you have a wealth of knowledge about electronics, software, and a DIY heart.

[@Sahta99]

Can these be put in the wall? Behind a regular plug or a light switch?

[@mohsin12300]

Great video thanks If we have to run 2 devices like fan and light do we need 2 devices oe 1 can handle that ?

[@byronstrohm3288]

Any recommendations for iphone users?
