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.
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?

Is it possible to make the manual switch work as a three way with the blynk? I mean, if I hang up on one I can call the other regardless of position.
@ 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...?
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?
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.
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 ?
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 .
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 ?
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 .
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.

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?
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.
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.
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.

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.
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.
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
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...
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?

How can we connect only one switch to on off this light... any short-circuit problem.
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 ?
Just log in with same Blynk account credentials from different mobile
In my case everything is working fine but when I connect the board to the another power source like adapter or vin except PC it stop working.
Please use a stable DC power supply. It can also happens due to loose connections.
