How To: DIY Home Automation with NodeMCU And Amazon Alexa

[@jcwire1685]

Great video, can you tell me if I actually need a echo device to discover the nodemcu. Right now I have a fire tv cube and using the Alexa app on my iPhone and it doesn’t seem to be able to discover it

[@fusionermx]

Cool video... Say if we had 2 boards say NodeMCU1 and NodeMCU2 how would you control those...

[@marlontroy6238]

Hello, Nice project but I would like to know how Alexa echo is connecting to this device if remote access is needed. Or some other API or MQTT is needed?

[@DevangsinghSankhala]

Amazing intro! What are your thoughts on how to integrate a temperature and humidity sensor like the HDC2010 to make it turn a swamp cooler on or off? I have been trying to look into it because I do not have a central AC so cannot use the Alexa thermostat.

[@Themakersworkbench]

Sorry for the late upload everyone. I ran into several technical issues while filming and editing this video. From camera focusing and audio issues to Premiere Pro telling me that my GPU (a Nvidia GTX 970) was not compatible, to days searching for a fix, it is finally out. Again, I apologize for the late posting, but at least its out there now. Hope everyone finds it helpful in some way.

[@sandychatterjee7457]

I am using a 8 Channel Relay but when I turn on the relay with 3v3 output and ground it just turn on the light on the relay but the relay dont turn off or on any solution to this ?

[@Themakersworkbench]

Hello Sandipan, Yes, the 3.3v is not enough to energize the 5V coil that is inside the relays you are using. You need to power them separately with a 5V 500mAh source.

[@sandychatterjee7457]

I tried it power it from a 5v of arduino but then also it dont work but when I changed the relay pin from node to arduino and uploaded a relay test code it worked.

[@Themakersworkbench]

Can you send me info on the relay board? Manufacturer, photo, etc?

[@sandychatterjee7457]

Yes how can I contact you ?

[@stevensnead4833]

Did not work for me a newbie at it though. The LiquidCrystal_I2C.h gave an error that it could not be found. I put it in the directory of the program but did not work. Seems like it going to take a bit to get your code going. Thanks for all you did.

[@jaynesjunction]

Great video - and appears less difficult to try compared to other articles I have read. Couple questions for you... do you know if it is possible to ask Alexa to read a value, and return it... such as if a door is open, motion detected (variable set), etc?

[@Themakersworkbench]

+Ken Jaynes Thanks for the compliment. At the moment I do not think it's possible to have Alexa read strings back.

[@jaynesjunction]

I am wondering if via home-assistant would work - home-assistant.io/components/binary_sensor.rpi_gpio/ via Raspberry Pi though, not Arduino or ESP8266

[@Themakersworkbench]

+Ken Jaynes I'm not yet sure.

[@Themakersworkbench]

+Ken Jaynes It's possible. I know the esp8266 is quite popular with the home assistant people

[@NathanHedin]

I used your set up and everything works great! However, I can't seem to get Alexa to respond to anything but ON/OFF commands, even by changing the call backs. I'd like to use this setup to automate my mini-blinds, but it sounds a little awkward to say "Alexa, turn off/on the blinds". It works, but it would be better if "open/close" was an option. I have a genuine WEMO switch and it will turn OFF/ON in response to a verbal command of OPEN/CLOSE, OPEN/SHUT, etc. Is there a way to get the emulation to follow these commands?

[@k6tf]

GREAT video! How did you get Amazon Dot to read the text?

[@consig1iere294]

Charles, thank you so much for the code and the tutorial. This works flawlessly! You are awesome!

[@WOnken]

Great video. I wish you could do a project on an Echo switching those cheap 433 MHz remote power sockets. This would be a great alternative to those expensive Smart Plugs, sold TP-Link and others. There are a couple of videos, where those get switched by a NodeMCU, but none that includes an Echo...

[@Themakersworkbench]

That is on my list, and I have the hardware to do it, I just need a few days to put it all together, but I have to get my next home networking video out before then. Thanks for following along, and thanks for the kind words!

[@tazmaniachill]

Brilliant job on the application, have done a few switching projects using this board and they work fine, but I really liked the idea of using the L.C.D screen (geek factor and all that..) I have downloaded the ZIP file but I am unsure with what to do with the 5 other files that are needed - where do I put them and how do I include them - plus where do I get WiFiUDP.h from? - also i am getting an error saying "error compiling for board NodeMCU 1.0 (ESP - 12E Module) - I am assuming this is related to missing files? - any help or advice would be welcome !

[@tazmaniachill]

Well after a fair bit of head scratching I finally got the main part of the project working and its talking to my echo dot nicely and switching the relays... however, the LCD screen just sits their glowing blue and showing two rows of white squares (as I understand it, its in reset mode?) it does nothing when rebooting the NodeMcu and I have spent most of the day looking if I went wrong anywhere with connection etc, the LCD is the exact same one in the tut here, so am at a bit of a loss, and as their seems to be no activity here I fear this will have to go on the back burner for a while and i'll look for an alternative. Not all lost though at least I think I learnt something :)

[@morneleroux9067]

how did you manage to get the WiFiUdp.h file working? Having the same problem now

[@himanshuhanda5608]

[@93Bananaphone93]

You could use a RF-Outlet so u dont have to have a relay and mess around with mains-voltage. Iam planning to do so. I had something like that but with no voicecontrol. It was just an icon on my smartphone that i clicked on. Worked well but wasnt that cool without voicecontrol.

[@chityuulay]

Can you make step by step tutorial for using Alexa/Google dot controlled nodemcu to control relay that can put in computer on/off switch that can make computer shut down or turn on ? should be simple but i am totally new to this field.

[@americanpsychosis11]

Nvrmnd. I figured it out. Just made the extra tabs and pasted the files there. Not done yet, but seems like it might work.

[@joaonetocz]

Hey, do you have the wallpaper of your desk? so cool!

[@Athens428]

This may be a weird question but I am trying to wrap my head around the circuit in a house environment. I am planning on using a few of these relays around the house to make some of the wall outlets smart. When these get hooked up, is the circuit parallel or series? I am trying to make sure everything in my house stays to code and nothing will draw more than it should without tripping the breaker.

[@Themakersworkbench]

If you want to stick to code, you will want to buy something like Sonoff switches and work them into a separate utility box in your mechanical / electrical closet. Using open relays like this inside of a wall is very dangerous, and unless they are UL approved, and in a fire safe box, it will not be up to code.

[@Athens428]

I was planning on putting them in the attic (with the rest of my wiring) and inside proper electrical junction boxes. I was mostly concerned with load on the circuit breaker and if these would keep the same amount of load as the original outlets that are in parallel. Edit: As a note, i am planning on having an electrician verify my work.

[@Themakersworkbench]

Benjamin H these particular relays are only capable of 10a of current each and I would not put more that 8.5 amps on each one. Typical wall outlet circuits are on a 15a circuit breaker which is able to handle 15a across that who circuit.

[@Athens428]

Right, most likely none of my lamps will draw more than 8.5 amps heh but i definitely see your point. Maybe the Sonoffs can pull more or a higher amperage multi-relay might be safer. My main question though is still the circuit type. A typical wall circuit has the outlets in parallel. My concern is that if one of the relays goes out that all of them will stop functioning.

[@travismicolichek8438]

Well thank you very much. I have 10 devices that are running with my echo. one of them is my garage door. There is one problem and that is that I cant figure out how to get the echo to respond to "Open,Close" commands. I can say "Garage door on" and "Garage door off" works fine. If you could help me that would be great.

[@Themakersworkbench]

+Travis Micolichek this is something I am trying to figure out as well for a new video. When I have it worked out I will share the details.

[@travismicolichek8438]

I have figured it out. I hooked an nodemcu and a relay to my garage door push button. I used a digitalWrite(relayFour, HIGH); delay (500); digitalWrite(relayFour, LOW); delay (500); digitalWrite(relayFour, HIGH); You don't need to change the code for open/close commands. You can use open/close command instead of on/off but alexa is picky about what you name your device. I tried "Alexa, open garage" and it works fine. If you say "Alexa, garage open" it dont work. You can also say activate and deactivate to control devices.

[@patrickbarrett211]

Is it possible to set the relays to pulse? So on the on command it switches on for 1 second and then switches off again?

[@himanshuhanda5608]

@TheMakersWorkbench My alexa is not discovering my NOdeMCU, i can see in the WIFI that nodemcu successfully logs in? Can you let me know what could I be missing out on?

Hello, Can the echo be used from a remote network to control nodeMCU that is connected to the home wifi ?

+Justin Jose I am not sure if this is possible and I believe that Amazon has security measures in place to prevent this exact thing. I could be wrong though as I have not spent any time researching it.

[@siddhantshah4587]

Does this need Internet to work ? Or just the WiFi Connectivity (I mean what if i disconnect the CAT6 cable from the Router but keep it Running, so will it work without connecting to the Internet ?)

[@dannymartin4225]

Why did you change the relay from the LinkNode R4 to the Sainsmart relay? I made the other project using the LinkNode R4 and have had trouble with the relay going on and off?

[@Themakersworkbench]

I'm not really sure what you are asking. I made this video to show people how to use the Node MCU to do the same thing that I did with the LinkNode R4.

[@dannymartin4225]

My question was, were you having a problem with the LInkNode R4 and was that why you changed to the Sainsmart relay? I wanted to know since I had built the first version using the LInkNode R4 relay and got everything working great with the Echo. However after the outlet stayed on a little while the power would cycle (on then off then back on again). This happened all the time the outlet was on. I changed to another LinkNode R4 only with the same result. I have contacted the seller and am awaiting a reply. I just was curious if you had a similar experience and changed relays. Thanks

[@Themakersworkbench]

I have the Linknode running the poweroutlet to my PC right now, and it has been solid for 15+ hours a day of use for the last two weeks with no issues. I am not sure what could be causing it to reset like that.

what low voltage device is at each light/receptacle

[@Themakersworkbench]

Dean D'Aiuto I'm unsure of what you are asking.

[@deandaiuto]

you have a low voltage wire running to each light/receptacle. what is that connected to to communicate with the arduino?

[@Themakersworkbench]

No, those are not low voltage. The black wires are the Hot wires from the 120V mains, there is a Neutral wire and Ground wire traveling to each from the main junction box as well, you just can not see them. The Hot wires (Black) travel from each gang box to one side of their respective relays, and then the other side of each relay is connected to the mains 120V hot wire in the main junction box. The only low voltage on this project is the 5V that travels into the NodeMCU from the USB adapter, and then the 5V that powers the coils in each relay. Please, if you do not understand how mains voltage wiring works, do not attempt to build this project. It can and will kill you.
