Hello to you!
I tried my Hello World project which consist in a NodeMCU ESP8266 (ESP-12) and DHT11 sensor.
I manage to have connection and send the data to Cayenne.
I implemented the Deep sleep function by connecting the Pin D0 to RST. NodeMCU works fine, goes intro Deep Sleep and then came out.
The goal is to send the Temp and the relative humidity once at 1 minute (the code below send at 15 seconds for debugging purposes).
Therefore, the code is run once in the void setup().
In the serial console, all is OK but when checked into the Cayenne Data history, I see that the NodeMCU sensor send the data about 10 times in a second!
Here is the Serial output from NodeMCU:
So, this are my questions:
Why there are multiple entries if I send the data only once?
How to send the temp and the Hum only once?
Here is the code:
