a picture would be helpful. If the ADXL345 is on a breakboard, like the picture!!

@Yada-Kijsathan .Hello this forum is pretty lazy.
You must connect the Arduino to the accelerometer board. If you are working with the Arduino IDE, you must load the current library for the accelerometer board. There you will also find out the connection between the Arduino and the accelerometer board. The programmed Arduino then outputs the values ​​on the serial interface, that the computer can read.

can also reach sleeping nodes with ota_configuration

I don't have a home controller. The sensor network and the gateway are enough for me if
I could place the humidity control and an html server on the gateway.
my sensors: arduino pro mini, rf24, and humidity sensor. unfortunately I can't find an entry point on how to extract the humidity values, for example, for processing.
Maybe someone can give me a tip? Best with an example.
