IoT based ESP8266 projects using Google Assistant Alexa & Cadio

In this IoT project, I have explained how to make IoT based ESP8266 projects using Google Assistant, Amazon Alexa and Cadio to control relays with voice commands and manual switches. I have used all the free tools for this IoT-based home automation system.

During this Internet of things tutorial video, I covered the following topics:
00:52 Quick demo on ESP8266 Cadio Home Automation system.
02:45 Required components for NodeMCU ESP8266 project.
02:54 Circuit diagram of ESP8266 IoT project.
04:59 Download Cadio firmware for ESP8266.
05:12 Install the Cadio firmware to ESP8266.
05:59 Configure ESP8266 using Cadio app.
08:23 How to Add Timer in Cadio app.
09:09 Connect Google Home with the Cadio.
09:37 Connect Amazon Alexa with the Cadio.
10:19 Update WiFi details through OTA

Important points:
1. Download the latest firmware from the Cadio Download Center.
2. In Free Plan, you have reupload the firmware after every 500hr
3. Reset the ESP8266 and wait for 30 sec to go to Config mode.
4. To change the WiFi details, Go to config mode, then enter the WiFi credentials from Cadio app.
5. The Boot will fail if the D3 (GPIO-0) (switch-2) pin are connected with the ground during booting.
6. If you use Switch (latched), make sure the switch-1 & switch-2 should be OFF during the ESP8266 Boot.
7. You don't need any Echo devices.
8. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltage.

During the Cadio tutorial video, I explained all the steps to make IoT based home automation system using ESP8266 NodeMCU and Cadio. This is the most easiest IoT platform for beginner, as it required no coding skill. You can do all the configuration from Cadio mobile app.
You can also add timer or create schedule in Cadio app to control the relays automatically. The NodeMCU can also remember the previous states of the relays.

If the NodeMCU is connected with Wi-Fi, then you can control the relays from anywhere in the world with Cadio Alexa and Google Assistant. And you can also monitor the real-time feedback on the Cadio, Amazon Alexa, and Google Home IoT applications. So with this smart home project, you can convert any appliance to IoT devices and control them through the internet.

So, now you can just ask Alexa or Google Assistant, "Hey Google, turn on lights" that's it.

Hi! Thank you so much for your detailed instructions of controlling my esp32 by alexa thru cadio apps. I am sure i will enroll to your tutorial course soon.

[your.free.electrons]

Hi, will this project work with the esp8266-01 module?

[muhammadnor]

I really like this project, it's easier and more complete, thank you sir for sharing your knowledge

[anhtuanngo]

Can you guide use IR control 4 relay with cadio ?

[ankitjha]

I have esp8266 v3. Push 1 with gpio 10 (S3) is not working with push btn. I tried 5-6 times.

[domnick]

is there a way to turn on all relays at once with 1 command??

[bhaveshk_]

Sir, 1 question.

Which use jumper wire typ?? (Male to female ya male tomale) answer

[sumantsagar]

Is the manual switch two way switch(spdt) or one way (spst)

[wsnjpln]

hi, after configuration device is not showing in cadioapp can u plz tell me why its not showing to me and sometimes com port also not showing for me

[arbaaz]

What if internet connectivity failure, How can i switch to normal switch

[musayyibkhan]

Thank you for sharing such a beautiful video. Please guide me because my one switch is working but other is not. I checked the wiring and configs but no luck. Same switch works in case wiring is switched between both switches.

[udhayakumara]

What it means showing "trial"? Do we need to pay after trial period?

[yuvarajnaidu]

Can we combine this Project and ur universal remote problem... Please reply is yes what pins should I change

[SarathiGhosh]

How do you know GPIO address for Configuration is D8 - 15 ? Can you also let me know GPIO address for configuration for ESP-01 ?

[yuvarajnaidu]

Hi, I'm really looking for same, can I have a same circuit with touch sensor ttp223

[nk]

Sir I have a question why we use only 5V relay and not 12V or 24V relay. sir why we don't use relay with optocoupler. Sir I want to automate my bathroom geyser since it is high power.

[yuvarajnaidu]

Hi, small request can you please share the diagram printout layout to make using acrylic sheet.

[aroadtosuccess]

Sir,
Problem is in code sinric pro.h error.Please tell me
I copied you code after some changes.

[jeffordjameslogrono]

hi can i use this esp 8266 for 8 relay?

[BeautifulEarth-qmov]

can i use more than 4 switch? if answer is yes then how
