- In this IoT project, I have shown how to make wifi smart home automation system with manual switches using NodeMCU ESP8266, Blynk, and relay module. With this internet of things project, you can control four home appliances from the Blynk app and manual switches with and without internet and you can also monitor real-time feedback in the Blynk App. So this is a very useful homemade smart home device that you can easily make with NodeMCU, Relay Module, Push Buttons.
For this ESP8266 home automation project, I have not used any custom design PCB. I have used the Blynk IoT applications to control the relay from the smartphone through WiFi. And instead of pushbuttons, you can also connect manual switches or touch sensors to control the home appliances.

There is no option like COM 7
It's not uploading wt to do
bro 8 channel relay ke liye code bato ESP8266
The subject aside, the way you explain is very well articulated. I can easily say that you are in top 3 in explaining technique in home automation in the world. Earned my sub.
anh là người chỉ dạy thật lòng nhất tui từng thấy,thực hành được 100%,chúc anh nhiều sức khỏe cảm ơn rất nhiều.
didn't even make this exact project but this was still helpful
Glad it helped
This is the new way to control our home appliances 👍and i think this the best way
wow! I've been looking for like this tutorial, direct to the point and very accurate. thanks brother! 1 thumbs-up for you! 👍 and a heart ❤
You are Welcome
Great video, to the point video
Thanks
thanks buddy for push switch option!
Welcome
Yes brother yahi chahiye tha
Can you tell connection and program for single relay module
Well explained IoT Project... Keep it up.....
Thanks for sharing👍👍👍👍
You are welcome
Thank you for the video, I have a question?
How do I setup a smart relay to a push button switch (door bell switch) so that i can switch it on using a phone app ?
In the example code I got from blynk the physical button doesn't work without internet. Sometimes it works for a short period of time but with a slow response.
Sir, In Place of Bulb, Can I Use 5V DC Motor?
Bro your video is super and made my own home automation using your guidance but only one problem I face, I have done as you done this project but 1 relay in 4 channel starts to work abnormal. (e.g. it's turning on and off automatically without any inputs). Can you guide in this difficulty..Thanks in advance
Hey bro
Check the relay module led with its respective channel
If its not working maybe the problem is with your relay channel
And if the led is working properly
Then the relay must be damaged
Nodemcu have more than 8 Gpio can I use it for control more than 4 relays.what is the maximum Gpio's can I use thank you
Very good & useful project 😍😍💕💕💕💕
Nice vedio so much informative
I have a question If I turn off wifi and change the led state once .
Then it will updated on dashboard when I connect to wifi again?
For eg-
*Wifi on*
0,0,0,0
*wifi off*
0,0,1,1
Will this new state be shown on dashboard as I turn wifi ON
Thanks so much for the incomparable & helpful video...Sir, tech studycell must be among the awarded learning platform in the world, by God's grace it will become one of among 10 in the. I love this platform. If I should have the opportunity to support or contribute to your platform I will, because you deserve a wonderful kudos from the people or Engineering students...
Very Good we are really enjoying learning new project can learn us hot to add a touch sensor instead of pus button
ok
Thanks for your exceptional good video, patience and the hard working behind all of these. Is it possible to make the AC Dimmer which runs both Blynk app by using slider button (or "+ve" & "-VE" buttons instead of slider ) and two physical touch sensor switches (say 4 pcs TTP223 or 1 PCS TTP 224 for controlling 4 steps ...etc. ) for manual Control (Increasing or decreasing the bulb intensity or fan speed ) , If so please make a video particularly in coding part, It is difficult to relating the physical two buttons with Blink slider in coding part.
It is more better to add 2 more button for controlling 2 ac loads (Just on and off ). Thanks
What if any kid pressed the recommended switch for a long time ? Will it not be reset ?
Sir, how to add voice control , IR control & display for the circuit.
I couldn’t get to set my esp8266 and esp32 running in my Arduino ide even after installing Python 2.7.3 and pyserial from adafruit. I have downloaded the drivers and installed the board in Arduino ide. The port is “com 28” and I think I used “nodemcu 1.0 module 12E” for esp8266 or there about! ( I am using CP2102 chip) The device manager shown that the hardware was properly installed and ready to use. If I try to open the serial monitor in Arduino it will never open, instead I will see “error com port 28 busy” If I upload code on the boards it pops out bunch of errors among which is “error opening serial port” or something like that.
I am frustrated, I need help please!
Instal a driver
After upload the code, the nodemcu wifi blue led not turning on although it already connected to wife
I connect ttp223 touch button but when I press it turns off normal but when I press again it blinking the light on off on off
bhai plz make a video of all in one, like 4 light and fan also with speed slow & fast with blynk app..
u made me biggest fan of ur interesting videos
No it can't use as a regulator , it's signal to relay for on and off
It would be cool to see it expanded with MCP23017 to 8 buttons and 8 relays, or even more with additional MCP chip.
I will publish the ESP32 with 8-channel relay module in this week.
@@TechStudyCell That is good, but it is another thing than using expqnder chip which can be expanded to 128 GPIO if needed over just 2 wires. Pretty usefull. Think about it. ;)
simple & perfect!
Thanks

Cool brother, need a 8 channel with feedback as a upgraded version of this
For 8 channel you have to use ESP32
@@TechStudyCell sure, can u make a video regarding this
@@TechStudyCell can't do 8 channel in esp 8266?
please reply sir
Can we charge a mobile and show it in the school project
My nord mcu does not connect to wifi. Light stays on for 4seconds and turns off
It's not uploading for port com 8 or 9 as there is no option of com 7
I can say one thing, You'll gain a lot of subscribers. Just keep uploading this types of quality content. Btw, Can it remember the last state during blackout?
But how to control light dimmer or fan speed control?
How I'm manage different user with different esp with single app in home automation
Brother blynk application is updated and we don't have same buttons and processes
Brother i can not be able to upload my code neither on esp 32 and esp8266
Good explain, I don't know about nod mcu and programming, but want to make it soon, I think the mannual swich is bell switch. I can't understand the diagram
Hello Sir
Need your help
Program uploaded successfully but device not getting configured for Blynk IoT app, please help us
Thank you bhaya for the video...🙏🙏
Hopeless!! Blink is not working. It works with manual switches, but could not be controlled via internet, blue on bord LED not on, but I know it is connected (serial monitor shows "connected") What should I do?
Nice bro💘💘❤
Brother please tell me if main electricity gone after on the light or is the light on after electricity come back
Bro my node mcu is not connect the wifi
And not working
Please suggest solution
???
At which range of distance it will work? if we're not present in home n losed wifi connection then ?
my board is not showing "serial port COM7", there is only COM10, COM9, COM3, COM9. I have chosen the same board as you have shown.
Bro did you got COM7??
'esptool.FatalError: Failed to connect to ESP8266: Timed out waiting for packet header,' This error is Coming sir
Sir, in Data Stream
Int 1/255, it is coming sir, how?
Does this work if it’s connected to Wi-Fi at my house and I’m 30km away ??
i wanted to automate my house with dimmer as well but i wanted atleast 8 relays so i tried to edit the code but then saw that you used random digital pins and as i am no professional i couldnt find out which pin to use to add more relays
Bro I don't know how to thanks you.my circuit works 🙏🙏🙏🙏❤️❤️❤️❤️ 1000000 thanks
Great 👍
How about the code, If I use switch instead of button?
can we turn onn ac from this
or any high load electric applinces
How do I change old code to Blynk legacy code?
Very nice 👍
Thank you 👍
i want to connect this setup with pzem 004T energy device..can you provide me for this circuit diagram..& necessary code for measurement power,volatge,amp with pzem004t with nodemcu & 4 channel relay board
No need any arduino to programme the node mcu?
hello, I'm doing the esp32 project. I ran into a small problem, I would appreciate it if you could help. Please
Is there no way to stop the reset on a power on ?. Because all the relays are on.
excellent project friend, I only loaded a query to an esp but it does not connect to the internet, and I do everything but it does not work.
I want to use with touch switch with the led showing that it is on and off..... Dont know how to adapt to that project
After power cut does it remember it's last relay state or does it start new please tell me
Thank you for such a good video. I had one question. Which simulator did u use to make the circuit diagram?
Can you attach the links the library functions
Touch sensor apart from Bhai push button Can we do it and can get its code, brother
hello wonderfull project
but my 1 question how many switch connect in nodemcu (manual + blynk app)
please give me answer
Thank You
Hi, I can't flash the sketch. BlynkSimpleEsp8266.h: No such file or directory
Helo! Greetings from Brazil! Thank you for your sharing! Great videos!
Sorry for my ignorance, but I have a question. May I use (for example) two buttons as a "push" instead "switch"?
I've modified only on Blynk, but I noticed when I press (and hold) the physical button, the Blynk (virtual) button keep blinking.
Excuse-me! English is not my first language...
Thanks a lot!
Regards, my friend!
Thanks. If you want to use switch instead of push button, then you have to modify the code. For reference you can check this video ua-cam.com/video/Sx9akwBwK4g/v-deo.html
What name written for esp32s in sketch
Make a clear video for all connection, because I can't understad all wire connected to relay board for 4 relay
Thank you so much. What will be the code if I use EEPROM in this project. TIA
Great work but please i find it difficult to upload the code
Sir my push button pin is not working please send me solution
Sir can you please sale this Home Automation for my daughter's school project? 😢
How we can use mannual button instead of push button in this video code?
