Any clues how to connect with an Alecto WS-1150

Hi everyone.

Recently i've bought an Alecto weather station, hoping to connect it with the Arduino. However, the existing libraries doesn't work on the Alecto... I'm quite clueless with the 433-sniffer i've downloaded, i get too many noise to make anything out of the 0's and 1's... Does anyone have experience in connecting with an Alecto weather station? Or does anyone know a better sniffing-program?

Greetings, Cybrarian.
