Hi. I made your project and it works perfectly even on a "thousand holes" board. I would like to ask you if you can add, if you haven't already, how to control each relay with a timer managed by blynk. Tankyou
Nice work. Need help in getting the relay on for momentarily when I say to switch on the relay from Google Assistant. Right now it just switchs ON and be at that state untill I say to switch OFF. I just want it to switch ON for 2 sec and then automatically switch OFF.
Nice video dear, i have using 4 relay module with nodemcu for different load, in my case im using local push button switch and blynk app soft button. i plan to update program which you given on description box below... many thanks.........................
Great work: But i want... when i press the push button ''indicator on mobile screen should be on' and when release the push button it should go turn off?. is there any solution? what changes should be made in the code for this?.
Brother please make a project video on manual switch, blutooth and also attach fan regulator using esp32. Please bhai.....My big support always with u.. 🙏
Is module pe 4 relay he..ispe or 1 relay add karna jayega ka?nodemcu 8266 par 2 out put pin avivi khali ha.(D3 and D8)iape ak push switch or ak out put relay ke liye?hoga ka?ancer plz.
Just i worked with your project, i was trying little different as its a feedback status, i uploaded same codes to two 8266, to work like a transmitter and receiver vice verse, it did not help, but the feedback from both mcu shows in blynk. could you please help me..
This is what I'm struggeling with for last week. Thanks bro! However. I got 16 physical buttons and the same number of relays. May I assign variables in loops ?
Bro I have node mcu + relay module and I made this home automation but I want 12v RGB LED strip controlling in this project can you modify this pcb ???
I'm using three pieces NodeMCU v3 on my house, since 6 months. I can control the lights, building door and see door status (open or close) etc. For this project, I modified my light switches to push button with using a little spring. They working as really push button. I recommend..
@@Metehan647250 Does the switch or button work if internet is not there?? Pls tell.. and did ur electricity bill increase after keeping this.. Pls reply
@@Crunchworks79 I did not follow my electricity bill carefully. But there was no significant difference. The buttons start working after the device is connected to the internet. It must be connected to the internet at first opening. Buttons continue to work even if the connection is lost after connecting to the internet once. But data cannot be sent to the blynk server. Therefore, we cannot see the button status in the application.
what an awesome video sir. Can i ask you a question sir? i tried to make a simple project to blinking two leds using nodemcu and blynk app, but i got a problem that there is a delay for 5-10 seconds since the button on the app get preseed until the led goes on (and same when tried to turn the led off from on), can you help me with this sir? thankyou
I have made this for my home, but unable to make it work with my switchboard as this is for latching pushbutton operation. I need help to switch on relay only upto the time switch is on, if switch is off relay have to be off. Please help !
Hello, First of all thank you for very informative videos. Not just this but for all. Second I had a question. Here we have used almost all of the GPIO pin of nodemcu. Is there any way to increase it. I have 7 switches at my home and to convert all do I need to add 2 MCU or is there any other way ?
@@ViralScience Thank you for quick reply. Yes we can connect to esp32 But still there is a limit. Is there any way to overcome that limit. I tried to search it but had no luck.

How to control that only one light can be turned on at a time, for example, when the first switch is pressed, only the first light can be turned on, and then the second light is turned on by pressing the second switch, and the first light must be turned off at the same time.

I'm using three pieces NodeMCU v3 with this codes on my house, since 6 months.

Hi friend your projects iam like it But small changes your project button is not use the button you want used switch and wifi network connection manual button function control
Thank you for tutorial , it work perfectly But i have just one thing Can i make the physical switch to send only [“0”] to turn on the relay I mean i use the physical switch to just turning on the relay , without turn it off when i push it for second time
hassan ahmed basha & viral science , can you please tell me what i need to change in the code to use physical switches instead of push buttons, i have succeeded to make every thing working like this video with push button, but when i use switch it is sequentially toggling And by the way it is a very great video, i was searching many times to achieve the light status

Your channel is superb becous you explain very simply and all things show
I've been waiting this video fromm this channel, awesome 🤘 keep it up
Nice projects 👏 I need this thanks lot
This is the most practical way of implementing home automation system. 👍
So how to get the feedback on blynk or whatever interface u design without sensors? Wut did he do here in the code?
@danish i wouldn't say this is practical. Suppose if your wifi is down you literally can operate your your room's lights
