#27 Dta recording starts 1970 / File Format issue

[Raphael]

Hello, first of all thanks for the great tool. It really helped me in the past to optimize my heating system.
Before the winter starts I wanted to check the system again but I am not able to load the dta.

DataFormat starts with 1970 an the charts / tables show wrong data. I used the firmware wpreg.V1.88.3 and wpreg.V1.88.0 w/o success.

I can confirm that I see the same problem with the attached DTA file. Debugging could take a while.

The 1st dateset in the attached DTA file is malformed. Thus, everything else is read wrong. Also the number of datasets the file contains is not equivalent to the number in the header.
If this problem still persists, please provide another DTA file.

hello opendta, i have the same issue since a few months. Suddenly the dta files show the date of 1970, each time i download the files with a usb drive.
Attached is one dta file. Are you able to open that one?
Im using version 2.0 with Windows, luxtronik V1.88.3-9717.

I noticed something:
if i download the data from: http://ip-address/proclog they are fine
but from http://ip-address/NewProc they show 1970.
So something must have changed in the data format.
I'll add the dta files here.

These are the last good dataset (31.03) and the first bad dataset (02.04).
I changed the IP to get remote access. And also one is wintertime, the other one summertime.

what i see, the first datapoint has only data but no date.
If i delete the first 30 bytes (see screenshot), then dta is shown with good dates.
I checked different files, sometimes i have to delete 60 bytes, before the first full datapoint of 70 bytes comes.

I come to a similar result. Unfortunately, I have not found a marker, when to remove how many bytes. With the current knowledge, these are broken DTA files for me.
