I found some unused pearl (cheap german electronics reseller, mostly “crappy” things) rf weather sensors in a trunk of my dad. http://www.pearl.de/a-NC7159-3041.shtml;jsessionid=nCBFDD55EC605E2436C07CE9CBCF12106
My pimatic homeduino get’s the following for nr 1:

As you can see, with rf-preset wearther1, you get correct values for the temperature (and the battery, i guess, it’s just new ones 
), but the humidity comes with horrible wrong values: Around (and above) 100% and around 15% for the other sensor.
Is there a possibility to get correct values out of those, or is there a need for a new protocol? Or are they just broken (the humidity sensor, temperature works fine, as i tested with other devices)
Thanks a lot for any help!
