Nice, thanks for the example.

Please enclose the source code between 4 backtick characters to format it correctly in the forum.

Backtick == ` x 4

Can you share the wiring diagram ?

[Mrlynx]

@Ezequiel-Torres I did just connect pin 3,4,5 and vcc,gnd to module and sensor to module. Look in example code for directions.
Example is made for mysensors 1.4 or 1.5 so may have to modify it a bit.

IDE upload:

MySensors.h:328:2: error: #error No forward link or gateway feature activated. This means nowhere to send messages! Pretty pointless.

example has to be converted to 2.x of mysensors.
To do so you need at least to add
#define MY_RADIO_NRF24
remove all gw.
please look at any 2.x example to see what have changed.

[wthiess]

I can not understand that!
I have not Radio my Arduino ist connect per USB.

[Anticimex]

@wthiess How do you plan to communicate with any sensors/actuators if you have no radio/supported transport attached???

[Anticimex]

@wthiess You need to use a supported transport.

[wthiess]

USB / Serial
/dev/serial/by-id/usb-FTDI_FT232R_USB_UART_A700RH5J-if00-port0@9600

[Anticimex]

@wthiess I suggest you read up on what MySensors is.
Here is a good start: https://www.mysensors.org/about/network

If you are not going to use mysensors look at library example
