How To: DIY Home Automation With ESP8266 and Amazon Alexa! 

Jody Cochran thank! glad I could help

Thanks!

Thanks!

Thanks!

+Terra-Ignition thanks!

Thanks Nolan!

Go it working. Thanks.

Thanks!

Thanks Becky!

Check back on 2/10/2017 for a Node MCU and 4-channel Relay Board tutorial.

Made it and it's running. Thanks very much.

I get this error too on both the Linknode and Node MCUs. I usually have to unplug the serial cable, and the power from the unit, plug it back in and all seems to work fine. Make sure the programming jumper is in the right configuration.

+Stuff With Kirby from what I can recall, GPIO16 does not stay high.

Thanks for becoming a Patron Alan! If the Echo can not find the Node MCU make sure it is connected to your WiFi and that both devices are on the same SSID. If the Echo is on a 5GHz and the Node MCU is on the 2.4GHz SSID, they will not find each other. In the past two weeks I have seen some reports of people having to enable the WeMo skill, on their Echo first, but it was already enabled by default for me. I am not sure if it comes disabled in the latest update or something.

I will have it ready in a few weeks. A few other things to finish up before I can get around to it.

Could you use this instead? www.amazon.com/Blue3D-Ft232rl-Serial-Adapter-Arduino/dp/B012YUANZK/ref=sr_1_8?s=electronics&ie=UTF8&qid=1490558089&sr=1-8&keywords=FTDI+Serial+TTL-232+USB+Cable

I simply had to ask "Alexa discover devices" and it worked fine, but some people are having to enable the WeMo skill first. It use to be enabled by default, but it appears that is no longer the case.

In the switch.cpp file you should be able to change the device serial number to something unique to each device, and that will allow multiple units. I am not sure if the WeMo skill is limited to 14 switches total or if it is limited to 14 switches per device though.

Worked great on the 8266-01!

Awesome!

You did a great job

Thanks Darrin!

I will see what I can do over the next couple of weeks.

subbed, look foward to that video...

I am not sure if this will work with EchoPi. I have yet to try.

+韋凡陳 I'm not sure. Sorry.

Make sure that none of the sentax has changed. I just downloaded my code from github and it's working fine for me. I am not sure what could be causing that error.

Thanks for the reply. After some time looking into it, i found that the compiling error was caused by the main library folder needed to be renamed and simplified to where it does not contain any characters other than letters and numbers.

Yes ...no problem

Yes, in fact that is how I came to find the Linknode R4. I was looking for a pre-built ESP8266 4-channel relay board. I had previously built a DIY relay and ESP8266 solution.

+Raymond Bradshaw Unfortunately not. The Wemo app will not recognize the device running the Fauxmo code.

I didn't necessarily mean the wemo app, I notice you linked to the LinkNode R4 Android APK for remote control, is it possible to retain this code and control it from this remotely as well as by Alexa? That would be the icing on the Cake!

I'm sorry I guess I misread your original question. Technically the two pieces of code could be merged, but as it sits right now, it is one or the other. If you check out my github, a few people have forked the code, and are working on a better solution for the WiFi, so maybe once their fork is finished, we can fork their code to include the Linknode R4 App code.

That would be great its a long time since I did any coding etc (Z80 machine code in the 80s). Have been quoted 20 to 40 days for delivery from ali-express as they don't seem to be available in the UK. So I have plenty of time to brush up my skills.

The LinkNode R4 can be bought on Amazon and has Prime too! amzn.to/2iB9C1P

Technically it should still work as long as the WeMo skill works on the Pi. That may be a future video if there is interest!

yes plz, when you will upload the same video

Hey Luis, Are you trying to control relays with bluetooth? Give me a little more info, and I will see what I can do.

Could u give me ur mail to send you more info?

Sure shoot me an email at themakersworkbench at gmail

I have updated the link to the R4 that appears to be back in stock at $10

In theory, yes.

That video will be out tomorrow! Thanks for watching!

Thanks for that I will subscribe and wait for it.

So any updates about that tomorrows video?

I get this error too on both the Linknode and Node MCUs. I usually have to unplug the serial cable, and the power from the unit, plug it back in and all seems to work fine.

I finally fixed it, but I basically just kept moving around the jumpers and doing things to reset it. It just seemed to randomly work once every 20ish times. Anyways I have it set up now and it works amazingly thanks so much!

As far as this project goes, you can set the trigger words in the code, and they can be anything you want them to be. If you are talking about Alexa trigger words in general, a quick google search will come up with dozens of different words, phrases, and skills you can use to do many different things with Alexa.

Ok as long as I say "Alexa, turn xxxxxx" on or off right ? Because if I say "Alexa, T.V. on" She can't understand it. What if I what to use "Alexa, turn channel up" .... what would be needed to do, for recognize the "up" word ?

+Tim M is your TV compatible with alexa? Im not sure what you are asking. Do you have the linknode connected to your tv? If so, all it can do is turn on the power going to your tv, not the tv itself. This tutorial is more so for things like lights, fans and other on/off type things

Ok sorry for the crypto question :) My goal is to use Alexa to turn on my infrared things, such as TV, amplifier aso. It's a expansion of yours and 3 other project ...Heres a bit of my sketch : /* Declare Samsung TV callbacks (on-off) */ void SamsungTVOn(); //Samsung TV toggle ON/OFF void SamsungTVOff(); //Samsung TV toggle ON/OFF void SamsungMuteOn(); //Samsung TV Mute void SamsungChannelUp(); //Samsung TV Channal up void SamsungChannelDown(); //Samsung TV Channal Down void SamsungVolumeUp(); //Samsung TV Volume up void SamsungVolumeDown(); //Samsung TV Volume down void SamsungCH1On(); //Samsung TV Ch 1 void SamsungCH2On(); //Samsung TV Ch 2 void SamsungCH3On(); //Samsung TV Ch 3 /* Declare Marantz callbacks (on-off) */ void AmplifierOn(); //Amplifier ON void AmplifierOff(); //Amplifier OFF void AmplifierVolumeUp(); //Amplifier volume up void AmplifierVolumeDown(); //Amplifier volume down void AmplifierAuxOn(); //Amplifier Aux input void AmplifierTunerOn(); //Amplifier Tuner input void AmplifierTvOn(); //Amplifier TV input void AmplifierDVDOn(); //Amplifier DVD input void AmplifierScourceUp(); //Amplifier Source up void AmplifierScourceDown(); //Amplifier Source down void AmplifierMuteOn(); //Amplifier Mute toggle void AmplifierMuteOff(); //Amplifier Mute toggle /* Declare Mile callbacks (on-off) */ void VacuumCleanerOn(); //Vaccum Cleaner toggle ON void VacuumCleanerCornerOn(); //Corners ON void VacuumCleanerGoOn(); //Go Go Go void VacuumCleanerBaseOn(); //Return to home But I'm having troubles getting Alexa to understand the UP/Down commands. Probably because she don't know them. I think I will have to create a Skill for her to understand UP/Down commands. (Or find a skill who will match) I'm also planning to use dimmers for the light, but it will come later. You can see some of my project here: github.com/tvixen/Wemo-for-Alexa I just thought that you might have a list over words we can trigger Alexa with, In this context?

+Tim M try the words tee vee instead of TV

Nicholas Lenzo its self contained.

Fan Freaking Tastic. Awesome. You made my day!

Nicholas Lenzo awesome! can you give a hint about your project?

Its most likely going to be a Base station that uses esp8266 or ethernet to listen for Alexa, then send out to cheaper units that control outlets using the nrf24l01. I have several lamps in my house that are very annoying to turn on/off. Probably going to make a Website to control it as well.

look into the home assistant project. I'm working on a tutorial now on how to use those cheap remote controlled outlets from Amazon using an esp8266 and alexa

I will see what I can do over the next few weeks.

Good deal! Or you could still include your Raspberry Pi, MQTT, and Home Assistant to have multiple ways to control this!

On my echo I did not, but I have seen a few people say that they had to enable the WeMo skill on their echo dot that was purchased within the last month. So I am not sure if a software update disabled the WeMo skill or not.

Yes - i got that far this afternoon. The Wemo skill used to be one of the available skill selections but apparently it is now built in to the Echo Dot so it cant be selected and I think the assumption is made that these devices will work by default. Unfortunately, while it might work for genuine Wemo device, I have no way of knowing, it doesn't for this project. That is a shame. Where do I go from here?

Alan Powell, Were you able to make it work?

I didn't have to enable anything on my Echo (about a year old) or a new dot. Just had Alexa search.

Not in this version of the code, and I am not sure if anyone has successfully modified the fauxMo code to set a timer on WeMo switches yet.

hi. hello great video... i got mine woking fine. istrate away.. i used a esp-12E . and a seperate 8way relay board.... ( sorted all woks 5star) is it possible if you could tell me how to add to the code so that im using the esp-12e ( 8) gpio pins to switch 8 individual outlets.. on the relay board please... im not to sure about the port area numbers... 81/82/ ..... then to add another 6 thank you. i
