I was learning how to handle the i2c communication using libmraa in python on the Intel Edison Arduino Borad. But I realized that the library does not allow to send only the the slave's address, without any data. That piont it's important, because the sensor HIH6130 needs to receive only its address to start a measure of temperature and humidity. What can I do? Is there an example to handle this kind of sensor?
You won’t be able to do that unless you change the source code of the library. I suggest you to use the Arduino IDE. In the Arduino IDE you can send the address individually. You can find more information about MRAA here.
