Hi Steve,
I've installed the new version and have had some wacky readings (rainfall, temp, pressure...) since then, but I certainly can't rule out the possibility that something in my set-up is creating the aberrant readings (which are then being faithfully recorded by Cumulus). I'll try re-jigging a few things and then see what happens before wasting any more of your valuable time right now.
Welcome to the Cumulus Support forum.

High readings when station loses communication with sensor
Re: High readings when station loses communication with sensor
Sorry to be so slow getting back to you, I've installed both updates and am collecting data, I've already had some strange readings but I'll leave it run for a while more with the latest update before I post up another bug report. I'm starting to wonder if the fault lies with the USB/serial convertor, I've seen one or two similar errors showing up in Heavy Weather.
I'm hoping to get my hands on a secondhand PC to use 24/7 as a weather server, maybe that might make a difference, I'm not sure if it (Dell Optiplex GX620) has a serial port maybe that might cure the problem.

Re: High readings when station loses communication with sensor
I was going to ask if you were using a serial/usb connector, I've read that some of these can cause problems. I'm not saying it isn't Cumulus's fault; it may be that it drives the serial port in such a way that causes problems...

Re: High readings when station loses communication with sensor
There's a bug in build 670 which affects anyone using inches Hg for pressure. My checks for bad data are using mb/hPa values, so everything is rejected if you use inHg. I thought I had all the checks allowing for units sorted out, but that one's slipped through.

Re: High readings when station loses communication with sensor
Well, I collected my "weather PC" and have it installed in the attic with the WS2300 connected via serial for the last few hours. No strange readings yet even though I've had a connection dropout (more on that below), this time when the connection dropped ( there seems to be two ways the 2300 itself deals with this, sometimes the display shows OFL and others just -) the Cumulus display showed the last good reading, is that the way you wanted Steve?
When I started the fresh install of Cumulus on the weather PC (use data-logger was ticked by default) Cumulus downloaded the historic data from the station, but seemed to become a little confused because the monthly total reported from the station was higher than it seemed to expect, it was adding the difference into this hours total. I decided at that stage to make another clean install this time unticking use data-logger, and all seems to be working as expected.
I have the PC uploading to http://weather.kilmoneynet.com/ if anyone's interested.

PS. The WS2300 definitely doesn't like DECT phones, the attic where I put the weather PC (to keep it clear of the kids) also is home to my networking and VOIP gear including a DECT base station, it lost contact within 20 minutes and didn't reconnect till I pulled the power on the DECT setup.

I wouldn't exactly say it was the way I wanted, but yes, it's the way Cumulus works.cilldara wrote: the Cumulus display showed the last good reading, is that the way you wanted Steve?

Re: High readings when station loses communication with sensor
Just a very quick update, everything has been running just fine since I've had the station connected via serial to my "new" old PC.
Probably worth my time sorting out a proper radiation shield for the temp sensor and a better site for the anemometer now.
It looks pretty certain the intermittent spikes were caused by the USB/serial converter.

Re: High readings when station loses communication with sensor
Congratulations on the serial discovery. This encourages me to try adding a serial PCI card in case the USB is also manufacturing my wacky data...
Re: High readings when station loses communication with sensor
An update, for archival posterity:
I installed a serial PCI-e x1 card (curse these modern motherboards...!) and connected via that. Since then (> 48 hours), no erroneous readings on any front. The source of the problem seems to have been resolved - and my sincere apologies for having raised a non-problem!
Now I just need to pluck up courage to tackle my defective wind sensor...

Re: High readings when station loses communication with sensor
No problem. It does appear from Google that the majority of problems people have with these stations are where they are using a USB convertor. I think it's because LaCrosse seem to have their own interpretation of the RS232 spec.
