Weatherlink Sample Templates
Hi all I just installed my davis vantage vue about a week ago. I purchased the weatherlink IP data loger when I purchased the station.
My question is this, I just found cumulus 2 days ago, I have the weather link software running on one of my computer system running windows 7 and this is the system that uploads my data to cwop, weatherbug, and weather underground, as well as the davis web site that they give you when you buy there product. My question it this, Can I have Cumulus running on say my laptop and still have the davis software running on the other computer?In doing this the davis software would still be sending the updates to the above and my laptop would just be looking at the weather station.In the past 2 days when I had this set up running it look like it was ok but when I checked my weather info at the findu web site it would all at once lose me and tell me that my station was 150 miles from the ukrane. My station is in the USA in Mass.
I would uninstall cumulus from my laptop refress the system running the weather link software and then It would so me back were i should be.Did I do something wrong? Or is it just that even that the programs are running on two diff computers it still can not be done.please help before i start to do this to my headThanksMark.

For testing purposes (and still testing as I write this message), on one WeatherLink IP are connected WeatherLink (the software), SoftWx VPLive and Cumulus (no error reported by Cumulus) - all three software are updating their data on a regular basis.You'll have to explain to me how that works, then, given that, as I understand it, the logger can only handle one TCP/IP connection at a time (hence the need for software to disconnect periodically to allow uploads to the Davis web site). Presumably this 'only one IP connection' theory is actually false, and there is some other restriction which prevent Davis web site uploads while a program is connected? 6555 - WeatherLinkIP Configuration Screen.jpgNormally, there is no need to modify any of the parameters.
With the default setup, the processor inside the WeatherLinkIP will send the data from the console to the WeatherLink Network web site - although I cannot technically prove this, from reading other post in other forums, it is my belief that the uploads are done every 10 seconds (if not more often). Steve wrote:but it seems that my belief that the logger can only maintain one TCP/IP connection at a time was incorrect. Steve, since I cannot prove it, it is my belief (as it was yours) that the WeatherLinkIP adapter can maintain only one connection at a time, more likely, forcing the other software to wait a few milli-seconds before they are able to connect and get their data.Steve, do you have the facility in Cumulus (through a function or something else) to test how long Cumulus is waiting or has waited before it was able to start the download of data?

But in any case, at the TCP/IP connection level, the DLL establishes the connection when Cumulus tells it to, and doesn't release it. So, if the logger could only support one connection, no other software would be able to read data at all while Cumulus was running.

Well, as long as Cumulus is running. Is that what is happening?Yes, that's right.There's the option to periodically release the connection, so that the WLIP can upload to the Davis web site.
Weatherlink Manual
I thought that was necessary because of the perceived 'only one TCP/IP connection' rule, but clearly there's more to it than that.
I'm about to run the install. I'm concerned that the Weather Underground data is updated every 15 minutes (more realistically it is 15 to 25 or so minutes). I do run WeatherLink 6.0.3 software on my PC and manually upload archives that are in 5 minute intervals. So there is a mix of 5 and 15 minute interval data on Weather Underground.I think I'll run the install and see how it goes.
Likely the 15 minute updates will be norm if I am too busy to upload archives manually.Any thoughts on whether I should do the reformat? We have a Davis Pro 2 Plus that uploads every 5 minutes to WeatherLink.com via Vantage Connect (a cellular connection). Unfortunately as we have discovered, WeatherLink.com only sends data to Weather Underground every 15 minutes, and it is not exactly 15 minutes as it can take 25 or more minutes at times.The WeatherLink software on my PC is able to retrieve the data from WeatherLink.com and it has the 5 minute data. So I can manually upload that when I have time. So that is why there is a mix.The install seemed to go well. It appears the data import from WU is a mess. I'll probably wipe it out and start over.
