So I have tried a few different things here , still same issues, not displaying proper values using your fritz template. Interesting fact is that I actually removed the DHT11 and of course it fails to read sensor but Blynk still shows readings as 70.66 for temperature and 89.00 for humidity. I disconnected the ESP8266 then started over and downloaded the program, pressed rst on board and still same results. Also note that the Green LED never turns on and Green timer always shows the off time .If I change it to current time , still no green led. I have checked the led and it indeed works when voltage is applied. On the app there are areas where you say to set to push but on the app there is no option to set push, this is all confusing ,not learning learning anything here as far as programming.
Hello Larry, I hope you are doing well and I apologize for the confusion. A few months ago, we’ve added the Blynk project as a Bonus to that course but we don’t even advertise it anywhere.
However, I wasn’t aware that our Blynk project was outdated, so we’ve decided to temporarily remove it while we work on updating it.
You can still access the pages here:

- https://rntlab.com/module-unassigned/extra-installing-the-esp8266-board-in-arduino-ide/
Blynk is actually not targeted to learn about programming. The goal is to just upload code and configure everything inside the app.
The best way to learn ESP8266 programming is to download the “Home Automation using ESP8266” eBook PDF and follow all projects: https://rntlab.com/module-1/welcome-to-home-automation-using-esp8266/
Now to answer your specific question.
Is your Blynk is showing an old value (70.66 for temperature and 89.00 for humidity)? That was probably a value that the DHT read at first.
What do you see in the Arduino IDE Serial Monitor?
Thanks for your patience!
