How to configure Blynk with the ESP32/ESP8266 - Arduino Tutorial

In this tutorial I will show you how to configure an ESP32 device within the Arduino IDE and connect it to the Blynk mobile App tp monitor/interact with a variety of projects, in this example a temperature and humidity monitor for a mini greenhouse.
More details and further tuturials are available at www.cabuu.com
The ESP32 device used in this tutorial can be purchased here:

You'll also need an DHT11 temperature and humidity sensor:

Christ, why cant every tutorial be as concise as this one. Thanks.

[@cabuu4122]

Thanks so much for your feedback!

[@dgamedesigner]

Thanks man. Finally I'm able to do something with the esp32
thanks a lot.

[@cabuu4122]

You're welcome, thanks for the feedback!

[@an_ancient_space_gamer3605]

you gained a sub man true and brilliant work great help i just got my first esp32 this helped me no actually made me able to setup blynk on it

[@janzandijk4398]

Thank you for you simple introduction to the Blynk world. :-)

[@cabuu4122]

No worries and thanks!

[@u5T30]

Thank you. Clear and concise instructions.👍

[@cabuu4122]

You're welcome! Thanks for the feedback

[@cveja69]

Works perfect!

[@kevintrout7158]

Hi thanks for your helpful tutorial!

[@cabuu4122]

Thanks, glad you found it useful

[@codexrat]

I wanted to ask one question,
The virtual pins you used in the app, how is the blynk app able to auto connect to the variables that hold the actual data of temperature and humidity in the esp board?
Maybe some code you edited in the IDE and didnt mention?

[@cabuu4122]

Hi there, the code i uploaded did not do this! Thanks for pointing this out, I have added a link to a corrected sketch, hopefully this answers your question

[@codexrat]

Ok, thanks for the quick reply!
Now it makes sense.
"Blynk.virtualWrite(V4, t);" is what i was looking for :)
thanks alot, now i can proceed to my project!

[@VishalYadav-oj9os]

Hello! I'm making the Solar powered Wifi weather station! Everything is righly done. The only problem is that the ESp8266 keeps getting connected and disconnected continuously from the BLynk ap. As a result i can't view my data! Please Help!
Please Help ASAP. Its my btech final year major project!

[@boim9312]

It's cool project

[@cabuu4122]

Thanks!

[@rizwanpathan6784]

thank you

You're welcome!

How can we use BlynkSimpleEsp8266.h library for Esp32 board.

[@soniyakadam6472]

Can ESP32S work according to this ?

[@kenwayjohn2919]

hello sir, can u make tutorial with esp32 with pH sensor and monitor using blynk?
oh yeah! one more, esp32 and TTGO esp32(built in LoRa) can use the same coding?

[@cabuu4122]

Sound slike a great idea, maybe! Good quality pH sensors can be quite expensive though...

[@nurashikinrohaime5324]

Can i still follow the steps one by one but with Esp8266??

[@hrishikeshgarud7177]

is there any way to download the sensor data from blynk?

[@cabuu4122]

Yes you can , you can export to CSV from the mobile app

[@honeybee8396]

Hello how are you.
doit esp32 devkit v1 no longer reads in wifi phone
Could you please help me?

[@cabuu4122]

Sorry I'm not sure I understand/can help with that

[@siddheshbarkale4102]

Thankyou for the video.

[@tothbalazs9385]

hy, i tried this and work well, than i changed the input pin from 13 to 34. Have you any idea why doesn't work than?

[@cabuu4122]

Hi there, if you changed the pin you will need to update the code to reflect this

[@tothbalazs9385]

Obviously, but the project doesn't work with the 34 pin. No problem i did it back. I just was curious.

[@kenwayjohn2919]

hello, sir need help with Blynk app here, I connect my two sensors which is temperature and ph sensor to esp32 dev board. the problem is my blynk app keeps telling me the value is 1 until 999 and so on for both sensor. but when i click on serial monitor at arduino ide the reading is ok. what is the problem? is it because of coding? please help me sir because i need to submit my work ASAP.
i am using
Blynk.virtualWrite(V5, millis() / 1000); for temp
Blynk.virtualWrite(V56 millis() / 1000); for ph

[@cabuu4122]

What are you printing in the serial monitor? I imagine it's something to do with Blynk converting to a string, try writing a pre-formatted string to Blynk.

[@kenwayjohn2919]

@@cabuu4122 yeah, i figured it out a couple of week ago. its my declaration at Blynk.virtualWrite(V5, millis() / 1000);
it should be
Blynk.virtualWrite(V5, temp);

[@scottmestel6146]

Perhaps you meant to say "natively supported" ? 0:53

[@abcorp7788]

ok

[@cabuu4122]

What's that? A camera? Not sure sorry
