During the video, I have shared the circuit and code for this IoT project. So after watching the complete tutorial video you can easily make this ESP32 Alexa smart home project.
There is a limitation, the ESP32, and the echo dot smart speaker should be connected with the same wifi network.
Soon I will publish the complete article on my website and share the link here.
If you face any issues please let me know in the comment section.

This looks AMAZING!!! Thank you so much for showing us this and NOT using Blynk etc., but using Alexa app. Perfect!
Glad it was helpful!
Excellent, I tried it after ordering the PCB and it worked properly. Many thanks for your creative ideas
Glad it helped. You can also share some pictures of home automation project at connect.techstudycell@gmail.com, we will showcase those in our website iotcircuithub.com
Thanks for the video, you helped a lot !! Don't stop recording videos that teach you how to program and assemble the setups. Thanks!!
Glad it helped!
Very cool Project / A lot of work / The PCB looks very nice / It´s 1 of my next projekts. Thank you
You are welcome
That is exactly what I was looking for. Thank you very much.👍
Glad it was helpful!
I liked the most. Really wonderful as perform superb and at last all devices connected to Echo Dot. in this Home Automation Project, no need 3rd party App, this is the main features which is all above. Once again thanks a lot.
You solved my problem. you're fantastic. Thank you!
You are welcome
Very useful home automation project using Alexa. Thanks for sharing.
You are welcome
hi, could you please tell me the kind of connection that the light switch have so I can try find the same compatible, thanks...
Very simple and professional approach. Especially loved the way you designed the PCB. Kudos!!
Glad you liked it!
Excellent, thanks bro :)
Thanks
complimenti per il tuo lavoro. volevo chiederti se è possibile comandare anche i motori delle tapparelle? Grazie
You always amaze with your new videos now make next video on mit app inventor with control of home automation by both wifi and bluetooth connection without any third party
if the power goes out do the switches remember their state? i.e if it was on before power loss do they turn back on on power resume and vice versa?
excelente trabajo. saludos desde México.
Amazing product.thanks for sharing.
Welcome
How can we apply the same (getting the feedback) while using the manual swtiches (that take power from home service panel) ?
Thanks
Thank you sir for sharing
Thanks
Worth trying
Can you make video about linking esp32 to smartthings app
Excelente implementación ingeniero gracias por compartir, un cordial saludo
Great project
But I have a question
Agar hamne relay 1 ya 2 ya koi bhi relays ko on kar rakha h via manual switch or electricity jane ke bad dobara ati h to kya vo relay activat hongi jo hamne manually ya blink app se on karke rakhi thi ?
nice, how can you apply this to a real life situation? If the switch is turned off you can with the Alexa turn it on the lamp? thaanks
Awesome video !
Glad you enjoyed it
Can I use NODEMCU v3 instead of Esp32? What will be the changes in the code for it .
I want to use NODEMCU v3 board and control 8 channel relay without blynk or any IFTTT apps
you produce such great videos!!, how hard is it to add Blynk into this, as I am converting a camper van project and want Alexa voice control but also use Blynk that allows me to have battery status, solar charge status, turn valves on etc from a central iPhone/iPad screen in Blynk (just learning and your videos are a great help...
. thank you in advance for your help
I understand that we can control fr bothe places..BUT...what happens to the manual switch logic.. if turn on the manual switch and then switch it off from internet?

is it compulsory to have echodot to add this switches
Excellent
Thanks
Preciso disso para um projeto de automação. Onde consigo uma placa igual com 10 canais?
Ou vc tem no canal alguma automação com placa de 10 canais?
Pode linkar?
Abraço!
Bro can you modify this project with controlling all appliances with dedicated Android app and also entering wifi credentials through app not from the code. Please try this project
Can we use push button or electric switch with same code? Please reply
Wich programa you use to design your PCB?
hi buddy..as this video..its means the esp32 is powered with 5v?
please make a video on wi-fi universal remote using esp8266 nodemcu & Alexa
Hy. Is it possible that we make two 8 channel PCBs and use it on amazon alexa app to make 16 channel home automation ?? Or in other words can we use multiple 8 channel control boards with multiple esp32 to make many channel home automation
Can this same be used for powerplugs
thanks . but can we do this without echo dot? caz in the video the echo dot was restarted to identify switches. whats the use of echo dot in this project?
Hello, ROK!
I have no Echo Dot. I did this project using the Android app Amazon Alexa and the switches weren't found by the app.
My smartphone and switches are on the same wifi. And I restarted both (smartphone and switches). Alexa coudn't recognize the switches.
Bro the wifi in esp32 board not auto connecting when we switch off hotspot and on. is there any way for that?
hello, when I compile I get the error "
button1Handler was not declared "and so on with all of the following (buttonNHandler). I followed everything step by step, load the libraries. What could it be? Thanks excellent video!!
Impressive and super useful as usual.
Can you make a tutorial how to increase esp32 pins using 16ch multiplexer please ?
