***Important Links:
Download Code for the ESP32 & NodeMCU home automation project from the following article.
iotcircuithub....
Blynk Cloud sign up: blynk.cloud/da...
Important points:
1. In code, you have to change the virtual pins according to the microcontroller numbers.
2. You can use different WiFi networks for each microcontroller, but the Authentication Token should be the same for all the microcontrollers.
3. Here Blynk cloud will treat all the microcontrollers as a single device as we have used the same AUTH token.
4. If the Wi-Fi is available, the ESP32 or ESP8266 will automatically connect with Blynk cloud and the status LED (blue) will turn ON.
5. If you use latched switch, then during reset the switch-2 (D3) must be turned OFF.
**Please take proper safety precautions while working with high voltages.
During this Blynk IoT tutorial video, I have explained all the steps to configure the new Blynk 2.0 platform for any IoT-based smart home automation system. If the NodeMCU or ESP32 is connected with the WiFi then you can control the relays from anywhere in the world from mobile, and monitor the real-time feedback in the Blynk IoT applications. So with this internet of things project, you can convert any home appliances to IoT devices and control them through the internet.

This is the reason I love this channel.
He shares every details,no custom pcb,no paid plans.🥰🥰
Thanks for the feedback.
Really it is a great opportunity for me to start watching ur valuable channel & wishing u all success.
Hi there, I am a big fan of you and watch your every video for almost 4 years. I appreciate your hard work and effort behind your all projects. I have seen more than one year, you do a lot of jobs behind home automation projects based on Blynk and another platform. It is very much appreciable. If you add a digital fan regulator with those home automation projects controlled by the Blynk app then it will be a great achievement for home automation. we see some beautiful good-looking sonoff or another wifi-based Chinese Fan regulator with touch switch panels which can be controlled by both App and touch panel switch (or physical buttons when the internet is not available) to control fan speed. still, now no RUclipsr/project maker makes such this type (physical Touch Panel+Zero Crossing Ckt+Blynk app) of project. As a fan, I hope you will make this for adding your existing home automating project and will give that project (full home automation)as a gift to your viewers if you have time.
confused between nodemcu CP2102($300) and CH340($235).....which one to go? can use the cheaper one??? are those function as same
Sir esp8266 is connect but esp32 is not connected automatically
Hello! i made the board for node mcu but im having a little trouble getting proper power? ANy suggesti9ons or have a better way to dm?
great video, use two ESP32 but response one at a time, plz hlp
@Tech StudyCell sir what do I need to change in sketch to use touch switch using tp223 instead of push button?
Sum time our network down problem the system is not working manual and auto
Hi and thanks for the video. I was wondering if it would be possible to use the sort of technilogy you are using to push a button on my mobile phone to activate horn or a buzzer on my car providing the car has no internet service to it. Say the car is parked in a large paking lot and l need to find it. Cheers
Thank u very much brother, can you refer best and quality electronics components where can we purchase please.
Dear sir sum tim link fail tha system is not working auto an manual
super and nice easy understanding all u projects i am happy😍
Thanks
Compilation error: blynk simpleesp8266.h: no file or directory
Very nice video. Can you suggest me what is the cheapest microcontroller that I can use for my IoT project? I need to connect with it through a SIM module. What is the best SIM module that will work perfectly with Indian SIM card?
Thanks in advance.
your video is very good, i am a big fan of you, hope you do video bynk 2.0, 8 relay, bluetooth and switch
There are some space issue. Will try again.
@@TechStudyCell I will support and accompany you, your channel is so good and useful
Nice project usefull for future home thank u sir u done great job
Thanks for the feedback
@@TechStudyCell I have suggestion can we use solid state relay instead of mechanical relay and is that enough to supply load to celling light celling strip light or ironbox wall plug what are thing do in solid state relay
If we use 4 esp32 then what are gpio available total 38 gpio available what are pin we can use relay and latch switch can u tell i have design my own pcb
i have completed the project its working but there is an issue that relays are turning on when switches are of and turning off when switches are on from both sides manual switches as well as from blynk app.... any one can help me here?
do you know if there is a way to made a button shortcut on my cell phone out of blynk (withouth launcing it)

This project is very useful, thank you
Welcome
Error: "Code_NodeMCUs_NEW_Blynk_4Relay_Button.ino:27:21: error: variable or field 'button1 Handler' declared void"
Line 27 is used to remember the prev state. "bool fetch_blynk_state = true;"
Then why this error getting?
@jineshcr3324
Brother can u decode that bug pls tell me how to do it
Your pcb with nodmcu built-in is available with you ? I want to buy, is it possible?
How to on/off all module a single click?
Hi friend! Can you make video and introduce this idea: in room N1 we have temperature sensor (DHT) connected to esp32, which is sending data to blynk server. other controller which is connected to the same blynk server and controlling relay using temperature measurements from room N1
hello friend, can I add a voltage sensor and add a water level sensor to monitor by the app
un proyecto exquisito, enhorabuena, podria pedirte por favor dado que no controlo arduino el sofwar pudieses publicar el codigo para un esp32 8 reles pero escrito con esphome? gracias
Great video 👍👍
Can we not add infrared control to this project? If yes how?
Please reply brother ❤️🙏🏻
In my esp blue led isn't blynking
Is it possible to control multiple ESP32s with one Arduino IoT Cloud dashboard?
im your fan thks
Can someone give tell one industry where the can use these abilities to make a decent living. I am trying to motivate the younger generation.
bro please make a lock using esp32 cam,fingerprint sensor of your phone and don't use solenoid lock please use servo in place of lock 👍
Отлично . Все получилось . Большое спасибо
What's program that your drow circuit ?
Great video
love it ♥♥♥
Thanks
Still it can do in blynk
Can we control these appliances from anywhere?
Well explained... Thanks for sharing👍👍👍👍👍👍
My pleasure
Will the code work with nodemcu v3
Bro it is asking for Blynk confi auth while uploading what to do now?
please reply ASAP
if you add wifi reset button. wifi login on phone will be great
Add LED for connection status (up time) on the app
Awesome !
Thanks!
Bro I need your help to make
My university lab automation project
I want to control 70 appliances
Can you help me to make this project possible
Please Guide me
Hi bro can we use any other pins than D3 so we don't need to worry if the pin is grounded or not for the node mcu to boot.
Can we use D4 instead of D3?
You can. But D4 has its own limitations. It is better to use ESP32
@@TechStudyCell I tried using D4 but same problem.Board wont start when D4 is low.
Then i tried another pins and my configurations are.
Relay
D0,D1,D2,D3
Binary Sensing
RX,D7,D6,SDD3
So far i have not been facing any issue while booting with all input pins grounded or any other issues while running.
Is this ok to be used for long time.
Hii sir can you please add remote control and voice control in this project, if possible please make it sir in next video
Thank you sir
TQ SO MUCH WORKING COOL
Welcome 😊
Can use each room node MCU only
sir please develop a voltage and ampere metre using node MCU or ESP 32 iot project
Can we need transformer???
LIGHT OFF NAI HO RAHE WO KASEY CHECK KARUN KUN NAI HO RAHE
Nice Project 👌👌👌
Thanks
Thanks a lot, i'll try soon
Great
Nice video bro
Thanks
is this need alexa
Hii.. can you add a circuit for controlling the speed of fan wirlessly by mobile
What's the magic word ?
Muy bueno saludos desde España
Muchísimas gracias
Sir mai electricion hu. Delhi pitampura se Mughe aap se bat karni hai please help
Sir kha yea automatically connect Wi-Fi say hota hai yea reset Karna hoga
It will connect automatically.
@@TechStudyCell hi esp32 switch code is not connect automatically
In it necessary to connect data cable to node mcu
No. Just provide 5V supply
@@TechStudyCell but When I am not connect the data cable from laptop it not working.
You have to give 5v across vin and gnd pin.
can using two esp8266 with blynk in the project ??
Yes. You can connect any number as per your requirement
@@TechStudyCell yah thank you
Here's my small doubt ,
Why are you (and also other RUclipsrs) limiting the project to only a few modes of operation?
Like wifi+manual (no infrared & no Bluetooth control & no voice assistant )
Wifi+manual+infrared (no Bluetooth)
What is the limitation here?
Please clarify..
I'm trying to make it for my home
And i need as many controls as possible
Please reply soon 🙏🏻🙏🏻
Connect and control it Google assistance ✌️
Use IFTTT, already made video on new Blynk and IFTTT
@@TechStudyCell ok boss.. i got it ✌️👍
Bahi 433 MHz receiver and transmiter bnayoo and manual
