Hi everyone,
As some of you may know I have a remote station situated in France. This morning checking conditions in WDL I noticed that although the web cam was updating the data was not. I have had disconnection problems in the past ( USB data logger ) but usually WDL says " no data since … " at that stage; on this occasion the time was changing but not the data. I used logmein to remotely connect to the computer and saw that WD was not updating. I closed WD and reopened it ( which is what I have done in the past except that before I installed logmein I had to wait until my next visit to France to do this ) and WD extracted data from the logger as normal but then I noticed that the actual temperature and minimum temperature were the same 7.4. I closed WD and opened and extracted data into Weatherlink and on viewing saw that the minimum temperature for today was 6.2 I reopened WD and then it showed actual and minimum temperatures at 8.1 ( obviously it had warmed up in the 20 mins. or so since the last opening ) . Looking at the graphs in WDL they just flatline from aroung 8.00 pm yesterday when it stopped receiving new data and in the records it now shows last night as the warmest night because it thinks the temp. stayed at 19.0 degrees all night. Is this normal and how do I correct the data. Thanks
It sounds like WD continued to send the same clientraw file. If WD is still running and the USB is locked up I think would produce the symptoms you described. WD would update the time, but the temps and other data from the wx station would not be changing giving you flatlined data in WDL.
I didn’t notice what station you have but if the missing data is in a datalogger from a vp2 you can go into WD and in the datalogger setup you can set a time to have WD go back and attempt to read the data from the logger. You set the time and then shutdow and restart WD and see if it can get the data imported from the logger.
Hi Dan,
Thanks for the reply. yes it is a VP2 and I followed your suggestion and set a time for WD to go back and re-read the data, but on restarting it still gives the same i.e. min temp 7.4 at 9.18 and last night still shows in the records as the warmest night which it certainly wasn’t.
Regards,
Steve
As a second alternative you could try WeatherLink and see if it will import the data. I could be wrong but I thought the datalogger still retained the data from the station if the USB stopped functioning…
Dan,
That’s the first thing I checked this morning ( see where I say about extracting data to weatherlink in the initial post ) Weatherlink has picked up all the data from the data logger I can see that in the graphs etc. At the moment WD is working fine but I can’t seem to get it to retrieve those several hours of missed data from the logger. p.s. I tried your suggestion again i.e. going into data logger and trying to get WD to re- read the data from just before the moment it dropped out but still no success.
Cheers,
Steve
So the data is in the logger…thats good news.
I will look and see if there is a FAQ but I think you might need to remove the missing time from the log file before doing the import. Otherwise I think it doubles up the data and what you see is still the original data from the log file. If I find some directions I will post you a link.
Thanks a lot.
Found some good info here that talks about how the process works and where WD stores the info. Might be useful.
Thanks again Dan, I will look through it.
Regards,
Steve
