**Important If you face the following ERROR, then please use the ESP32 board 1.0.3 version (old version). ERROR: Sketch uses 1333170 bytes (101%) of program storage space. And you don't need to install BluetoothSerial library separately.
I need to use switch both ways as in if I turn on a device using switch I can turn it off from blutooth and Blynk. Also I need to make it work with NodeMCU and HC-05 Module can you please suggest some changes. Waiting for your Reply.
Great project But I have a question Agar hamne relay 1 ya 2 ya koi bhi relays ko on kar rakha h via manual switch or electricity jane ke bad dobara ati h to kya vo relay activat hongi jo hamne manually ya blink app se on karke rakhi thi ?
hi subhajit, kya aap ek option add kr skte ho, ki jab hum bluetooth se oprate kre toh button ka color on hone pr green ho aur off krne pr red ho.. plz add some color for button in bluetooth app, yaa fir Button update ho on hone k baad ya disable ho off hone k baad.. baaki koi kami nhi h, iss superb project me.. i love you brada.... manmeet
Great video. I would like to create a PCB Gerber file, but please let me know the mounting parts. Please give me all the numerical values such as resistor values and transistors.
Can i switch on more than 1 relay with single button? Also is it possible to set delay of 20 seconds for one relay to start? also reverse process if turned off a button?
Really great job/project.I like what you do,and explain. The only issue wich i really found on this project,is that without wifi/bluetooth you can't control any more with the remaining manual switches...And as i see the code is permanently checking for wifi,wich is ok,but the loop must be adapted.I am wrong in what i say? Thanks for all this videos, Regards
Awesome, but dear can you add the option to the same code to update the io pins status with manual switches in Realtime still in bluetooth mode too as it has in wifi mode with BLYNK .
You could use Hi-Link power converter from 240v to 6v on your custom designed board instead of cellphone charger for power supply to ESP32 board. It would look like built-in power supply.
I'm turning on and off the fan using relay 8, most of the times the esp32 gets hanged after turning on the relay and shows wifi is offline in the BLYNK app, when this happens i can't control using manual button as they are also connected to esp32. The only way to start back the system is by hard resetting esp32. What I'm doing wrong suggest?
Sir i am making this project like blynk 2.0(wifi)+BT+manual with DOIT ESP32 DEVKIT V1 board but due to higher size of code i select board ESP DEV with Huge file option in partition for uploading the code, code is successfully uploaded working all perfect except board is not connected with wifi so i cant control via blynk so please give me any suggestion? i change the board?
Tech studycell, It is a great and clear video to viewer. May I ask your opinion if it is possible and worthwhile to use this ESP32 board to connect a joystick for home flight simulation software? Thank you very much for your sharing.
What website we can create and simulate the circuit when the other components is not available in tinkercad? Please hear me out for the sake of our project .
@ Hey thanks for replying can you elaborate a little that how did you made it work do you also change the connection and did you using simple switch or 2 way switch

What if suppose switch is in on position need to turn off light with wifi/Bluetooth, Must and should switch is in OFF position...? Otherwise it will not work...?
Good morning Sir. Please I didn't not succeed to connect the Bluetooth app with the ESP32. Please is it another way to disconnect the Wi-Fi? I did all that I know but the Bluetooth app is not going through
Hello Techstudycell, this project is great. I have made exactly this project and it is perfectly working. Thanks. But I have a problem. When wifi router is disconnected or restarts, esp32 gets disconnected, that's fine. But when the wifi router is back to working, esp32 does not reconnect back to the router, except I press the reset button. Please, how can I make esp32 reconnect with wifi without rebooting the esp32 board?
Hey Subhajeet sir, I just designed this circuit on zero PCB. Everything working fine for 2 to 3 minutes but after that ESP32 had short and getting very heat. Can you please tell what was happen?
Hello. I downloaded PCB_Gerber_ESP32_Relay_8channel_01 and created a board with JLCPCB. I assembled it, but it doesn't work even if I turn on the 5V power. Please tell me how to solve it.
Excellent work sir as usual. Sir all your projects are amazing and admirable. I requested earlier also if you can please add dimmer also in these projects it will be more useful and practical including relay on off status and dimer value display on OLED or LCD. Thanks in advance.
@@TechStudyCell Sir, could you please make a video on how to make Bluetooth home automation app using MIT app inventor in your upcoming video. Thank you sir

I mean how many mobile can control at same time the system ? because in code we define auth code belongs to APP the one that is different from each mobile APP ?

Sir I have followed all the steps correctly and installed at my home (2 Esp 32) but after 1 or 2 hours both esp 32 goes automatically offline mode and after that it works only after esp 32 power on off. Please suggest how can I correct. Waiting for answer.
Great job and one more inspiring video, also try to add 5 step fan speed control + google assistant as it is available in everyones phone and without fan control home automation is something like incomplete...
Hi Sir I see yours Great Projects And I like it And try to make it Dear sir make a Vedio a project control rely board with esp8266 but without internet Coz we have no internet
Bro bs ek problem solve kr do,ki jb light jati hai or jb light ati tab ye 0se start hota matlab jo button chalu the vo bhi band ho jate hai,agar ye memory store kr sakega toh koi problem nhi hogi,pls try to solve
Good project but I'm getting error while compiling code as Sketch uses 1333170 bytes (101%) of program storage space. Maximum is 1310720 bytes. Global variables use 52500 bytes (16%) of dynamic memory, leaving 275180 bytes for local variables. Maximum is 327680 bytes.
When i download bluetooth serial library from below link there is no option to download the library..and when i search the library in arduino ide skech manage library.the bluetoothserial not shown
Sir, i have one issue. While using wifi for controlling, when switching on the lights are getting switched off and while switching off its getting on. I tried in voice recognition mode also, it was working the same. What can be the problem, pls guide.
I try to make watching this video but my ESP32 unable to operate 5V relay .it's output was 3V only ,and I give extra 5v power supply to relay but signal pin unable to operate again .Is there any solution for this Sir..... Thanks ♥
Please watch the circuit carefully. It's better to use separate power supply but GND pin for both power supply should be connected. There are optocupler in the relay module. So 3v in signal pin is ok. Here I have used active low relay module, so when you connect 3v at control pin relay will turn off. If you connect GND pin in control pin relay will turn on.
