WOW - Crazy numbers today. I know it was warm, but not this warm.
Outdoor Max Temp = 161.8 Degrees F
Outdoor Max Dew = 143.8 Degrees F
Outdoor Max Heat Index = 617.7 Degrees F

Do you have some notifications in message box on "system" tab? If so, please post those.
To shed a bit light on this, reason is that Davis makes use of alternative Hum/Temp sensors in a very few stations. I don't have direct grip onto a station with these sensor types, so I cant test with full temperature/humidity range (putting it into my freezer and into boiling water). So you are one of the very few, where I can spot raw data for those sensor types. Do you have a somehow special equipped station? I am still puzzled, why Davis does have these two types (which I didn't believe in the first run).
So I am very interested to get the raw data that results into those artifacts.

Being patient paid off
Today your Meteobridge logged this data for me:
Code: Select all
logger (17.07.2014 05:04:35): station 0 (Meteostick), suspicious humidity reading: hum(last) 26(90)% (a0 00 6e ff 72 00 bb f8) -64db
logger (17.07.2014 05:06:18): station 0 (Meteostick), suspicious humidity reading: hum(last) 90(26)% (a0 00 6e 00 82 00 67 5a) -68db
logger (17.07.2014 05:07:09): station 0 (Meteostick), suspicious humidity reading: hum(last) 26(90)% (a0 00 6e ff 72 00 bb f8) -62db
I can see a wrap around on high humidity (>90%) in the fourth byte and a corresponding overflow bit in the fifth byte. Now it is easy to adapt the code. Please reboot to apply the new code
Now spotting for the high temperatures...
