Great tutorial! Had trouble with my ESP8266 not compiling. Turned out to be the SimpleTimer Library, here's how I learned to fix it: // Remove this //#include ... // Modify this //SimpleTimer timer; // into this BlynkTimer timer; Hope this helps anyone with this error. Thanks again!

I copied everything but with a DHT22 sensor. Changed the line to use DHTTYPE DHT22. In the serial monitor I get "Failed to read from DHT sensor" Any ideas where I should look for the error? EDIT: Found the error. The code says DHTPIN 2 but the comment says PIN 4. And the diagram also indicates to PIN 4. It was actually using PIN2. The Blynk app is also updating now. Fantastic!

@cranexdragon1046
@cranexdragon1046 4 года назад
Most likely not. Depending on the location if this was an outdoor garage or workspace that wouldnt be otherwise heated the humidity can easily jump if there is a slight decrease in temp.

Thanks for the Video. I am having an issue where I used the DHT11 sensor with Arduino Mega and the reading was very accurate compared with another AC controller and sensor that I bought from the store. But when I used the same sensor with ESP8266 the temp reading was accurate but the humidity was off by 5 to 10% which I found very odd. Any idea why is the difference, are you using the same dht11 library with Arduino and ESP8266. Also is there a way to read the fraction temp and humidity or it has to be full integer?
@uwestraube3765
@uwestraube3765 4 года назад
Good evening, I have rebuilt the sensor and works very well with the DHT11. But I want to make a sketch suggestion. A relay should be switched on at a certain temperature and switched off again at a low temperature. That would be great. 2 additional buttons in the Blynk app for on / off would be great. Can you help me with the sketch? Thank you

this is a devic you have to get the app for. the code is here but doesnt work either way.
