Lacrosse Weather Stations

I have two Lacrosse weather stations (one for each floor) and they both communicate wirelessly (most likely basic radio signals) to a sensor placed outside the house that relays what I believe are temperature and some basic weather variables.

Now, has anyone been able to hack/modify those to intercept the signal and use it in openHAB ? … or even better, been able to send weather data directly from the device to openHAB ?

There is a video on youtube from Andreas Spies how to access 433 Mhz devices
hope it helps you further.
