Welcome to te923 project homepage


A few years ago, I got a Mebus TE923 weather station. There was a very terrible java program shipped with this tool. I looked for a better software runing on linux if possible. But I found only closed source software witch costs money. So I startet to build my own software.

I user a windows software within a virtual maschine to reverse engineering the protocol used by the device. After some exhausting hours I got a very small command line tool witch reads the data from the weather station. I’ve called te923tool.

The te923tool supports most weather stations based on Hideki weather station like IROX Pro X, Mebus TE923 or TFA Nexus. Some other hardware is supported but not all devices are testet yet. Feel free to make a test and give me a feedback if it works or fix the programm if it not works.
