Weird Dew Points
« on: October 17, 2019, 11:37:45 AM »
Since I switched to the WifiLogger I'm occasionally seeing dew points of -1 in my Weather Underground page.

see the graph here https://www.wunderground.com/dashboard/pws/KTXODESS12/graph/2019-10-16/2019-10-16/daily  (WU link)
(The summary also reflects -1 as the day's low dew point.)

This appears to have started only when I started using the WifiLogger.
Note that the -1 dew point seems to always be at the top of the hour or half-hour.
In the WFL setup, the update is 5 minutes (int: 5 seconds), RapidFire: Disabled

The -1 dew point does not appear in my Weatherlink app data.  Maybe there's something on the WU end that is causing this but, as I said, it has only started since I began using the WifiLogger in about August.

Has anyone else see this?  Or have an explanation?

Thanks

Check that nothing else is also uploading to WU. That includes your old Weatherlink.com device for your old WeatherlinkIP logger. Make sure that Cumulus etc is also not uploading to WU. Make sure that only the WFL is uploading to WU.

If you aren't certain that you may have missed something that may still be uploading to WU then temporarily disable the WFL from uploading to WU (disabled in its configuration for WU but keep it plugged in and running). Then sit and watch your WU account for an hour and see if anything got uploaded.  If you do see data that something else is uploading to WU then let it go longer and eventually within hours I think WU will show you the type of software that is uploading by clicking on the information "i" in the black circle at the end of your station name.

After going through your helpful suggestions Iím still at a loss for the reason for the anomaly.

If no one else is seeing the strange points Iíll just keep trying to figure it out. Itís not a big deal since my archived data is not affected but Iím still curious as to whatís happening.

I will check what is wrong little later, but problem is not with temp and hum, but with wind gust.
I will repair that, but I need some research why it happen.

I noticed that these strange pressure occurrences only seem to happen during daylight hours.

I also noticed you are only uploading to WU every 5 minutes. Maybe that is part of the problem. Is there a reason you don't have WU set for rapidfire uploads? I think uploading every 5 or 10 seconds is good. If you change the upload interval then maybe the problem goes away.

I hadn't even noticed the corresponding wind gust data.  Nice job.

I was thinking rapidfire uploads were just unnecessary traffic (even though we're talking about a very small amount).  But, I have changed to rapidfire every 10 seconds just to see if the wind gust anomaly persists in that setting.  After the problem is resolved I may or may not leave it that way.

Thanks for your help.

I think rapidfire uploads is one of the biggest appeals for Weather Underground. There isn't another service that has this feature. The only other way to get "live" data is to run your own website. I wouldn't say that it is unnecessary traffic.  You get to see live data at any time remotely. And it amounts like you said to negligible bandwidth. I've looked at my rapidfire upload (every 16 seconds) and it amounted to 9 MB/day. I doubt that it affects even those with limited bandwidth. I think that there may have been a time when this was significant data (for those on cellular Internet) but I can't imagine anyone still on an antiquated data plan that was so restrictive. I say leave it on rapidfire. Even if you don't need it, maybe a neighbor of yours will appreciate it.

In my opinion this is WiFiLogger problem.
Please let me know firmware version.
Please go to SETUP| Network info and check if last boot is not the same like dew point spike on WU.

Yes. I have seen that after my post.

Please update WFL to version 2.25.

Checking in here to say I have had the same problem with the -1 dew point reading for the majority of this year. Does 2.25 firmware fix this?

The -1 shows up for me on WU and PWS Weather. Does not show up on WL or MesoWest.

Since updating to 2.25 and changing my WU upload to Rapid Fire I still occasionally see the -1 dew point in the WU daily high/low summary but I have not seen -1 dew point in the charts or tables.
