I have no idea. I don't know if the memory location does what the unofficial memory map says it does. I don't know if I can read the location reliably. This is a La Crosse station, there are no rules, no official documentation.
Do you know someone who had this problem?
Not that I can remember.
about the last build, what exactly did you change about dayfile.txt?
I thought I'd said? I've changed the system calls that I use to write the file.

I have to admit that I don't like La Crosse and their weird protocols at all, but I'm not saying the problems with La Crosse Cumulus are all their fault, but it is very easy to search the web and find people complaining about them.

I would make it very clear if I did that!

Ok

help me understand this I just came home after being out for 10 h with Cumulus closed, I found out that the dew point has different values, if it's read from the datalogger (example) it logs 12°C , if it's "live" with Cumulus open it reads 7°C. I tried now to simulate the operation of this afternoon and that happened too. I discovered this watching the graphs where I see a direct drop when Cumulus is open and a vertical raise when Cumulus is closed.

Why? I don't have "calculate dew point/wind chill" selected. Should I?

I have no idea. If you don't have Cumulus calculating the dew point, then the value used is the value read from the station, whether it's live or from the logger.

You can get Cumulus to calculate the dew point if you want, it's up to you.

it must be a LaCrosse (of course) datalogger's bug, because it's the only there, the live data from the station is correct.

If you look at the coresponding temperatures and humidity, what should the dew point be in each case (live and logger)?

Hello is it possibile to add some cool webtags like moon illumination (%), the time and date of every new phase, distance from earth, date of perigee and apogee of the moon, and of the Earth. Time/Date of next Moon and Sun eclipses :D

Sandro, you'll be wanting astrological predictions and horoscopes next :shock: There are loads of almanac sites out there to satisfy your requirements.

The reason I use Cumulus is a clean display showing the weather. Here's hoping it always stays that way ;)

Hmm... yes; it could work: "You are going to post outlandish requests on a software support forum... and be disappointed."

ROFTL,
anyway I got a problem I don't understand everything was going perfect for 1 week, at 18.23 I got a false -28.8°C temp for 2 min and logged :( I thought that using the serial would eliminate the problem :(

I deleted the two lines, but the other files won't re-adjust. I could manually but I don't what the real min temp "of the day" and "all time" is

Load the day's data from your data file into Excel or similar, and sort on the temperature column.
and "all time" is
If you started Cumulus not long before the bad data, use the alltime.rec file from the latest backup folder. If your alltime.rec file is too old, load dayfile.txt into Excel and sort on the max temp column.
