Can't tell where the problem lies.
I have two Davis VP 2 stations I manage, one in Canada, one in the US. Both stations are using v4.4 on NSLU2s and update to Wunderground.
Two days ago, it rained in both locations at approximately the same time (7pm PDT). Meteohub correctly reported the precip amounts for that day on the stations respective sites, but Wunderground reported an identical precip amount for the next day (and reported the amount in the monthly total) even though id DID NOT rain the next day and indeed, no rain is graphed by Wunderground for that following day. In other words, Wunderground is reporting double the amount of precip that actually fell (as indicated by the Davis stations). :(
Wunderground has reported in the past few days that they have been experiencing problems with PWS, but is this a Meteohub issue or a Wunderground issue? Is it related to time (my stations record data in UTC but use local time for graphs)?
Any ideas?

Re:Wunderground "double" precip
Duplicate precip problem again...:S
It rained .09 on Aug22nd and Wunderground reported .09 on the 22nd and 23rd. I sent in a support request ticket, and here is their reply:
>>Hello,
Duplicating totals from the day before, is normally an issue with your time being off a bit. If you are not finding a bad time in your configuration, it may be an issue with Meteohub. Unfortunately we do not have any support help for Meteohub users yet. We are looking into this for the future, but until then, you can look for help through the Meteohub Forum:

I've noticed that my NSLU2 only adjusts its time during reboots, according to the NTP logfile. I've scheduled reboots once a week, but if time is the problem, perhaps meteohub should re-sync the clock daily?
Any ideas???
