First of all I want to thank you for the tutorial my friend! Second, if you want to use NodeMCU, u need to delete these 3 lines "#include " "#include " "#include " and replace them with these 2 lines so the code can use other libraries. "#include " "#include " It worked for me
Hi sir , I remembered while you said that you don’t like switch reversing like sonoff and you made fix the Manual switch position. But sir as of now we all using two way switches which are like sonoff switch no fixed ON /OFF positions. As per this whenever we connected the manual switch and automation then it’s like two way control only so please allow the switch reversing as this more useful. And when the physical switch turns on the device app get feed back as ON and if we turn of with app then the physical switch still in same last position only ...hope you got my point
yeah, I am thinking about the same problem. The only solution that I found to be useful here is that remembering the past switch position using EEPROM and a pushbutton so, it would be same if you used a regular manual switch. if the internet goes and comes back again then the led which were off would be off and those who were on would be on.
Thank you so much sir for this project, sir I kindly request you to make a video on AC dimmer project along with this home automation project using Blynk IOT platform.
Excellent, i am ameen from pakistan i have seen your NODE MCU ESP32 video. In which you have controlled the electric power. I have a problem. I would like to have a 3 stepper motor. clock and anti clock ways. Can you please tell me the circuit?
Hi Sir, Thank you so much, sir, for this project, sir I kindly request you to make a video on Like Make Wifi as a Hotspot and Control the devices offline, Also it will respond with physical switches. Control with local server.
Thanks for information! Please make a video on how to use blynk slider with ESP32 to use pwm function or make MIT app with slider.. hope to see from you soon. Thanks
It is possible to use internal pullup (inputpullup) fuction to 4 switches ... Plz tell it affects the board during pressing the button .. Im using nodemcu ( esp8266)
Sir I saw your best home automation project and it was best and you have used esp-32 wifi module but it is quit expensive than esp-8266 wifi module so instead of esp-32 module can I use esp-8266 module
Hello .. Facing a issue with nodemcu i made a home automation module as you stated in video .. Everything works fine but after an hours or two it goes in offline/sleep mode...how to fix it ??
Sir very informative video you made. Sir it will be wonderful if you add dimmer for fan also. And operate it on local blynk server. Your efforts are always appreciate by me. Thanks
sir iam using nodemcu 1.0 while compling the code their is error #error This code is intended to run on the ESP32 platform could you help me, i need this project
Thanks a lot but can you try to make it with ttp223 instead of normal switch and 1 thing also I wanted to know that will all coding s will be same for ttp223 as well or it'll be differ and if so pls let me know the circuit diagram & code, I'll be more thankful to you....
Amazing...one qns though...Why there are 3 LEDs to let us know the connection status of board can it be just single ? Like if connected it will turn on if not it won't?
Nice build bro 👍👍👍 Is that anyway to get the wattage consumption of individual load to relay. That will help us to calculate the exact electricity bill.
Hello, i am planning to install it on an existing lighting circuit. I am currently thinking a way on how i can get feedback from the existing local switches. There are circuits that uses 3 ways and 4ways switches. My plan is to replace thos 3ways to 4 ways so i can introduce an SPDT relay that is controlled by the microcontroller. Any thoughts about this?
Hi Buddy.. very Nice project bro.. definitely the work appreciated, i have a concern like If esp failed.. the manual switch will also fail.. didn’t you prevent from that ?…
Hi Sir, There is a bug in your code, in setup section, while device powering on time if internet is not available the code stucks on there and even physical switches not works, need a query "while wifi.begin " along with your without_internet function, so please update in github too... need to call the below function in setup function if no internet is available at boot up WiFi.begin(ssid, pass); while (WiFi.status() != WL_CONNECTED) { without_internet(); delay(500); Serial.print("."); }
Hi, may I know few details about the electrical wiring ? I guess I see that the line/live is connected to the appliance/light. Only the neutral part is controlled by the board. Is that safe /allowed ?
hello bro i need your help i am trying to make home automation using esp32 and i'm using your code and circuit diagram but i got a problem bro when i'm giving 5v supply esp32 is getting power but it is not connecting to my wi-fi when i removed the vin 5V supply to resistors/switchs then it connecting what i have to do ? please help me bro
Dear I hope you are safe and healthy. I already make the project and tested it's working well. I want to fix a small issue on this project. example: if connect to the relay1 Fan and turn on from blynk app while running the Fan disconnected the internet then it will turn off the Fan. so please how to fix the problem need your support. need to stable the relay previous state I hop your reply Thanks
Hello Sachin, need a favour, need your help in pcb, wants to control 10 control appliances means 10 relays and want their live feedback, please help in coding, circuit diagram and pcb design asap.
hello sir I was having a problem in connecting to my wifi cuz its port is 8080 and the default blynk port is 80 but due to blynk .config function I am unable to change the port to 8080
Bt problem occurs whn u turned a pin high and cut off power supply and again supply (simply on restart) now pin is actually LOW but indicator will not show it. It doesn't have feedback..
Bro I tried this with one relay but my relay is constantly turning on and off. I think I have an infinite loop somewhere. Could you please help me out?
That's what I want.....it's a nice idea bro... Keep going....make this kind of awesome stuffs.... God bless u bro... stay home stay safe And....i got an idea, can u make a corona monitoring system that displays the affected,cured number's of people people' in india on a lcd module live from the internet ...I think it's possible right..
Actually....wat if nodemcu doesnt work due to some issue....but still in this condition u cant access the onoff using switch..... Wat i meant is...can we make this feedback circuit without going through the nodemcu....then it can work if nodemcu has a fault in it. Hope u got my point.
Great hard work sir, After watching your video i think u like a tony stark. I one request to u sir plz Plz make same project which run on local host ( device and mobile phone both same local network without intrrnet) and with internet ( if device in home and mobile phone app in remote place in that case by using internet we run device)
hi bro i aslo want make such kind of project but i want control 12 devices with both manual and internet but pcb board should be small and it should fit in that box .there is any way to make the small size pcb with more devices ..bro if you find any related information in real time .......
Thank u so much brother. If u r using esp32 it has a dual core CPU. This means u can execute different code on different cores, i made a home automation kit with dual core,. Core-0 for blynk & core-1 for Bluetooth control,
Hello techiesms, could you help me. I would like to know how do I get blynk to return the status value in the Google URL. Post, I have Jarvis IOT and he recognizes when a device has already been activated, but for that I needed the Blynk URL page to return some value of the button, example (off or on) and (0 or 1).
Sir plz can you make video on home automation without internet (means nodemcu has wifi router and by connect ur phone with nodemcu wifi range you can control ur appliances)
Sir in esp32 can we automatically change wifi and bluetooth in home automation....?if it is possible means 1st priority is given to the bluetooth...if bluetooth fails automatically connected to the wifi....how to do that...please explain and upload code for 4 relay
I turn on the device which is connected to the board while the internet is turned on as soon as the internet is disconnected the devices turned off what to do to stoping this.
Dear, I have 4, 8, 16 channel relay, I would like to use it with physical switch and with wifi, I have esp32. Please guide me so that I can use it with both, Thanks in adv.
First of all I want to thank you for the tutorial my friend!
Second, if you want to use NodeMCU, u need to delete these 3 lines
"#include
"
"#include "
"#include "
and replace them with these 2 lines so the code can use other libraries.
"#include
"
"#include "
It worked for me

Hi Buddy.. very Nice project bro.. definitely the work appreciated, i have a concern like If esp failed.. the manual switch will also fail.. didn’t you prevent from that ?…
It’s the same conditions as if the fuse get’s blast how can we turn on appliances
In both the cases you have to replace them simple
Great.. can we control these with alexa/google?
Thats awesome dude, I definitely gonna make this one for my shelter 👍👍👍👍👍👍
Amazing
Do share the video of your project after making
And also support us by sharing the video
Absulatally ultimate project but any idea with same project with 8 channel using pcf8574 io expander

hello bro
i need your help
i am trying to make home automation using esp32
and i'm using your code and circuit diagram
but i got a problem bro
when i'm giving 5v supply
esp32 is getting power
but it is not connecting to my wi-fi
when i removed the vin 5V supply to resistors/switchs then it connecting
what i have to do ? please help me bro
Is the hilink power supply is capable for give enough supply?
Yes. It is an 5v power supply. It is enough for powering the Esp32 board
But the max output current 600mamp
Here we have 4 relays and a esp32 with 3leds .
Please help me how to connect blynk virtual pins with ifttt and webhooks
Dear
I hope you are safe and healthy.
I already make the project and tested it's working well. I want to fix a small issue on this project.
example: if connect to the relay1 Fan and turn on from blynk app
while running the Fan disconnected the internet then it will turn off the Fan.
so please how to fix the problem need your support.
need to stable the relay previous state
I hop your reply
Thanks

Brother i did but i have one problem when system power off and on every relay goes on can we code power comes relays as off ?
This circuit is getting freeze, then and there and not working properly. Can u support and guide with u tips. Thank you
How much it cost to make a 4 channel design like you did, including the component cost like relay esp board etc.?
Great project, thanks for the effort it is on point instructive.
Can this circuit can be controlled with sinric With alexa or Apple Homekit and if yes can u show how to do and make a video on it .
Nice project.
If you have a available this pcb?
Bro I tried this with one relay but my relay is constantly turning on and off. I think I have an infinite loop somewhere. Could you please help me out?
Sir can you help me I have a problem when I uploading sketch on ESP 8266 it will show like this leaving hard resetting via RTS pin
Its common and not a problem
Hello there,Nice video..will node MCU work with the same code?
Sir, how may switch using this circuit
That's what I want.....it's a nice idea bro... Keep going....make this kind of awesome stuffs.... God bless u bro...
stay home stay safe
And....i got an idea, can u make a corona monitoring system that displays the affected,cured number's of people people' in india on a lcd module live from the internet ...I think it's possible right..
It’s possible and already made by many people recently
Hello sir,
These is nice project but can we add fan control using ac dimmer circuit with or without internet.
Sir that's awesome solution, need support for making this project
Actually....wat if nodemcu doesnt work due to some issue....but still in this condition u cant access the onoff using switch.....
Wat i meant is...can we make this feedback circuit without going through the nodemcu....then it can work if nodemcu has a fault in it.
Hope u got my point.
Sir where I can buy slide switch becoz I search on internet but I don't got any this type slide switch plz shere a buy link of slide switch.
Hi can super project and may I know which software u use to develop pcb
1-should be both esp and iPhone connect to the same WiFi?
2- can i use transistor instead of the physical switch ?
Can u please share the code and also circuit diagram without pcb (connection including resistor, transistor etc...)
What to do in the time of COVID bro, JLCPCB is very costly to ship via FedEx to India plus import duties extra, is there any alternative
can we use 220ohn resistor instead ok 10 k ...
Great hard work sir,
After watching your video i think u like a tony stark.
I one request to u sir plz
Plz make same project which run on local host ( device and mobile phone both same local network without intrrnet) and with internet ( if device in home and mobile phone app in remote place in that case by using internet we run device)
Is it working with Google assistant?
And how many switch can be worked ,i mean is it possible to increase 10 switch ?
Can this project be run with Nodemcu esp8266 board?
Can this project extend 4 device to 8/12/16 ??
there is an issue if nodemcu get damaged you will not able to use switch also
Hello, do you have this same project with the Esp8266-12-F module and work with WiFi Manager?
hi bro
i aslo want make such kind of project but i want control 12 devices with both manual and internet but pcb board should be small and it should fit in that box .there is any way to make the small size pcb with more devices ..bro if you find any related information in real time .......
