"Alexa, turn off Echo power." 😂😂

[@Mikomanus]

Very nice. The only thing i would change is to replace the 220VAC to 12VDC with 220VAC to 5V and then remove the 12V->5V AMS regulator to save some power. Too bad those SSR require 5V to operate. Otherwise i would go with 220AC > 3.3V DC directly. Also you can change the ESP frequency from default 240MHz to 80Mhz in the board menu. This will also save some power. And 240Mhz is not needed. Its not much but if you want to run this 24/7 its always nice to reduce the consumption as much as possible.

[@sunsethorizonstudios]

Imagine making a function “alexa hack Microsoft* 😂

[@gtcollection6933]

So sad this project is all arduino oriented (yet again) and not based on the official ESP-IDF/Eclipse libs and compiles. I think Espressif should have never SDK for arduino and leave that weak platform for what it is. What a mess. Great channel/host and efforts none the less.

I followed the instructions and received the error: Arduino: 1.8.19 (Linux), Board: "ESP32 Dev Module, Disabled, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), 240MHz (WiFi/BT), QIO, 80MHz, 4MB (32Mb), 921600, None" Build options changed, rebuilding all In file included from /home/jpmh/Arduino/libraries/FauxmoESP/examples/fauxmoESP_Basic/fauxmoESP_Basic.ino:7:0: /home/jpmh/Arduino/libraries/FauxmoESP/src/fauxmoESP.h:64:26: fatal error: AsyncTCP.h: No such file or directory compilation terminated. exit status 1 Error compiling for board ESP32 Dev Module.

[@sainathreddy753]

same for me, tooo

[@LeLaboDeHarry]

Nice video! Maybe you can implement Over The Air on the ESP32 (for remote code upload)

[@prahadeesh_mk]

Do a video about matter with esp32 it will help a lot . 😁

[@madhukeshnp]

Yes. That would be really good.

[@ramarastogi922]

One more masterpiece❤! It would great to see this aplication for Extension boards, Since most of us are not allowed to play with mains. BTW Great content❤️❤️

[@ignition_electronics2520]

🔥🔥Thats cool 🔥🔥🔥

[@PhG1961]

Awesome ! Now a similar project with the ESP, this time for Google Nest...

[@bobrowles43]

As always thank you for the content... very interesting. Two questions. Assuming the Arduino is using PWM to control the variable power on the green LED? If so I'm guessing PWM would not work through the relay? Second question. I use the pico and MicroPython for my projects. (haven't really embraced Arduino system). Any chance you might branch out to include more pico / MicroPython content? Thanks again!

[@ELECTRONOOBS]

The SSR should work with PWM for a basic incandescendt light bulb but it won't work for LED bulbs since they already have their regulating circuits. Normal coil relays won't work with PWM but a SSR module works more or less.

[@djokinac]

Greetings from Serbia I have one question, actually two do i have to have an alexa device or is an android mobile phone enough? and another question can it be made with an esp32 alexa device, but I don't need a speaker and a microphone it is enough to detect devices such as these switches or sonoff thank you very much in advance

[@CemeteryLarry]

My Alexa is going crazy because of this video lol

[@colinmcintyre1769]

That's cool, great invention. Can I put a US plug on that and plug it into the wall? I think my house was like 116 volts when I tested it. idk 🤷‍♂️.

[@NguyenDuong-lr9uk]

Hello sir I have connected wifi esp32, alexa and my phone to the same wifi like you says. But alexa doesn't find any new devices can you please help me with this?

[@FARMAN68]

How can i turn on off and speed up or slow down an AC Fan without using multiple relays?

[@prebengranberg2971]

Very interesting masterpiece :) Will be possible to upload Longitude and Latitude to show a map of the position in the near future ?

[@Dstilgenbauer]

Awesome! Thank you for sharing, great vid

[@OnkarJadhav-ik7kt]

What should be the TCP port for Echo 4th gen, as I am not able to find the device in alexa app

[@roycas3]

My devices started to misbehave. Could’ve muted the Alexa word.

[@drelectronics13]

Are you lacking bro ,this things are made by most of the youtubers ,it would have been better if you wud have written smooth working code for rainmaker

[@dennyfox3139]

I live in the USA, will your PCB run from 120VAC? Cool project! I have been getting Alexa control with ESP8266 and ESP32's using Tasmota and the Belkin emulation Tasmota provides.

[@ahmedabdulwaheed9877]

He is using a switch mode power supply to drop the Mains AC Voltage down to 12v DC and most of these supplies work from 85v AC all the way up to 250v AC. Just make sure you use the one that supports 120VAC input and you are good to go.

[@edwardfletcher7790]

The 5V is what's important, just use a local plugpack for your countries AC power.

[@LegitLeeVelez]

hello sir I went to your website and downloaded your ino file and I changed the ssid and password like it says in the code but alexa doesn't find any new devices can you please help me with this?

[@MikesTropicalTech]

I want to do this, but with Google or an independent voice recognition service. Then I want to have it drive a motor to crank up or down the window screens in my new apartment. I'll dive into the project once I get back to Barcelona.

[@kennic5382]

You make similar to the Google and Alexa controlling relay

[@iam726246]

I have a Bose brand speaker and it never detects the device, it never detects the device, does anyone know why?

[@colormaker5070]

You have great videos but please edit out Alexa wake word.

[@overbuiltautomotive1299]

why would any one need or want alexia or any of that nest camera stuff just odd

[@NETBotic]

It would be funny to make some prank bulbs where you tell Alexa to turn it off and it comes on.

[@telsonlancycrasta]

Chatgpt on ESP32 ?

[@Eckmuhl29]

Lol I was thinking about that lat week, but with a google assistant

[@tanishq.this_side]

hey brother love your project, recently I have a request can you make thermostate for alexa which means a stand alone device with an oled display and an encoder to set a temperature using temperature and humidity sensor bm"e" 280 sensor and feedback from esp to alexa where we can get the current room temperature from alexa and use it to control the smart plug of the air conditioner to turn off when it reaches set temperature and turn back on again when required. I am struggling

[@alistairmurray626]

I couldn't compile mine, i couldn't find the "esp32" library, so i downloaded the "Arduino_ESP32_OTA" one instead, didn't work though :(

[@ELECTRONOOBS]

Eso is not is library, is a board. You have to install the board from the boards manager and to find it add the json link. I have a guide on my website

[@alistairmurray626]

@@ELECTRONOOBS Thanks for the reply! I had the board already installed it turns out, i read the ReadMe file, and it said you also need to install the "AsyncTCP" board as well! so i did that and it works now!

[@anonuser2640]

Woww same project with me but I’m working with HomeKit

[@sainathreddy753]

same works for esp8266?

[@sammichael25]

You should upgrade this project to use Matter so you can control from Google and Apple etc. Plus there aren’t much tutorials online at the moment on the subject

[@ttssoon1975]

Why after i followed all your instructions and both alexa apps and esp32 connected to same wifi network, the alexa still cannot find the esp32 device eventhough how many times i tried? Can u advise?

[@afredzhou]

I also can not find

[@AkshatAgrawal-ld8bn]

Have u found the solution yet?

[@natureloverJ]

Awesome! what is the Alexa generation 3/4/5 in this demo ?

[@juanestebanrodriguez9742]

Tks for sharing your knowledge Electronoobs.

[@ingjuanz8624]

Excelente pero no me gusta desperdiciar tantos salidas del esp tengo algo parecido usando thasmota usando 8 reles

[@BeitEssentials]

you are amazing ❤❤❤

[@aliemlek]

👌👌👍👍

[@dinismaia]

Another very nice project 😃😃 5 🌟

[@jashuvasabbavarapu4053]

It's very amazing. We want complete tutorials of esp32 with different modules and different projects

[@NETBotic]

You should suggest something specific.

[@qqpp6017]

오

[@rahim9568]

Thank you, but do have any ideas to make it without the alexa-hardware maybe just as voice recognition software because the hardware it's not allowed in my country. I would appreciate it in advance, thank you again.

[@ELECTRONOOBS]

I might make It but with a raspberry pi instead...

[@rahim9568]

@@ELECTRONOOBS thanks for replying

[@revanthr3959]

Pls make a video on Cadio

[@AMoktar]

Awesome bro. Thanks

[@drelectronics13]

Do you know about Cadio iot platform

[@ELECTRONOOBS]

Nope

[@salufuabdullahi5828]

Very nice Project

[@teddyjamilonatefreire8797]

Is it possible to control brightness of any bulb?

[@ELECTRONOOBS]

Only incandescent bulbs, since LED bulbs already have their own regulating voltage circuit inside.. So if you want to control LEDs, you need to add a MOSFET and your own LEDs and not a stock LED light bulb

[@stevenA44]

I wish you and everyone else that makes stuff like this that are controlled by Alexa, would take into consideration that MANY MANY MANY people have The Alexa devices and when YOU ALL say Alexa, it activates OUR Alexa devices! It's really annoying! It is a cool project though.

[@ELECTRONOOBS]

Use headphones, hahaaha LOL
