THANKS ALOTS ALMOST AFTER THREE MONTHS I GET A OUTPUT FROM ESP8266 BY YOUR PROGRAM

Bijli cut kr aane ke baad relay ka position change kyon ho jaata hai yaani on rakhne pr bijli cut ke aane pr off ho jaata hai.

[@RakeshKumar-hs8yz]

Your channel is superb becous you explain very simply and all things show

[@shivaraghav2899]

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.. 🙏

[@DanishKhan-ty2pm]

This is the most practical way of implementing home automation system. 👍

[@mibrahim4245]

So how to get the feedback on blynk or whatever interface u design without sensors? Wut did he do here in the code?

[@hrithikjain1806]

@danish i wouldn't say this is practical. Suppose if your wifi is down you literally can operate your your room's lights

[@DanishKhan-ty2pm]

@@mibrahim4245 Please go through the code. Link is in the description below. There is no need of sensor to send feedback to the blynk app. Depending on the pushbutton state, whether it is HIGH or LOW, the feedback is sent.

[@DanishKhan-ty2pm]

@@hrithikjain1806 Even Google Home can not work without internet connectivity. In this project, if WiFi is down then there is a option to operate appliances using pushbuttons as we normally do. You can upgrade this project using ESP32, which has Bluetooth connectivity too..!

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

[@thesanjeevmymail]

Hi, First of all this is fantastic, Could you please mention the quantity and amp details about the items you have used in this project. As NodeMCU ESP8266 - Please provide link to buy this. Relay - 10Amp or 16amp with quantity Push Button (Tactile Button) - 4pins or 2 pins? 330 ohm resistor - quantity not mentioned 1N4007 Diode - quantity not mentioned LED - red or green and quantity not mentioned. BC547 / 2N2222 Transistor Block Terminal Connector - Quantity not mentioned PCB Header - Quantity Not mentioned 5V Power Adapter - buy link please. Please provide the above details so we can also make this same 2 same as you have made this. Thank you.

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.........................

[@mibrahim4245]

Thats awesome! But can anyone tell whats the main thing should be done to get a feedback of the physical switch? Without sensors as in this video

[@EKLAVYAVEER]

How much it cost to make a 4 channel design like you did, including the component cost like relay esp board etc.?

[@user-ri1sf6uy7h]

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.

[@maliarif2023]

Great!! nice work. I like the concept of your feedback control. I wanna make this one.asap.

[@Metehan647250]

@@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.
