Topic: Davis WL will not produce images or graphs

[chief-david]

New Davis Vantage Pro 6163
Vantage Vue console (need to look at firmware)
DIY data logger
VVP
Weatherlink 6.5
CP210x USB to Serial converter
Also running Weatherdisplay-for the main info

I would like Weatherlink to create a few graphs, TSHW, Dew point, a few others. But it wont. It will download the info, but stops. I get these errors.

It will not work with VVP. Running tcp/ip.

It will work if I am not going through VVP. 

I also took out the batteries, pulled the logger, and all the other stuff to reset it.

Garth has been a big help here, but I dont want to keep bugging him. He is busy too.

Any solutions are great.  I am also working on setting up VPSE

[Garth Bock]

Could you list the steps that you take to produce this error ?
I have 2 test setups...
1) DIY Logger and cable on an Envoy running 3.88 firmware with VVPro and VPSE. WL is on a TCP channel
2) Davis Logger on an Envoy running 3.88 firmware on VVPro and VPSE. WL on a TCP channel.

Walk me through the steps of generating the graphs. I would like to see if my test set up will produce the same results. I can click on Plot and Strip charts and those work fine.

I know it works fine without VVPro and VPSE, but it could still be something with the cable or DIY logger in combination with the software.

[chief-david]

That is about it. just trying to do this.
Internet settings....

hit ok.


It downloads, then stops and will not produce any of this. I do have to go in tomorrow so I can see the firmware on the console.

Wondering if I installed the correct serial to USB converter, But it both programs are working well.  or if there is some .dll that the computer does not have.

What does your Setup>Internet Settings window look like?

I dont have it set at a time because it is not working

Can't comment on the VVP and DIY logger, have no background on these but the graphs you are trying to create are not logger related (as such) and all done in the WL software. If you can manually download to WeatherLink 6.0.5 with your setup then so should the Data Upload profile if [Download Weather Station First] is checked. 

Have not used Internet Settings & profiles in WeatherLink to upload to the internet or a Local Path for quite some years but just setup a quick configure using Profile 1, added a Report file, 2 current data images and 2 historical Data images, upload every: 1 Hr, Starting at 0.03 and Download Weather Station First which has been running/downloading/uploading/ the selected report/images fine for the past few hours.

This is a Vantage Envoy & NanoSD but don't expect the Vue & DIY logger to be any different, all done WeatherLinkPC

I have run through some basic testing and here is what I have found....VVPro is the problem and VPSE is NOT the cause. WeatherLink seems to be the only one affected. If you want to run multiple weather programs (like I do), at this time WeatherLink will run, display and save data, but the graphic generation doesn't work.
On a Comport
1) DIYLogger ---> WeatherLink - Works fine and creates the graphics
2) DIYLogger ---> VSPE ---> VVPro ---> WeatherLink  - Fails and gives Loop errors
3) Davis Logger ---> WeatherLink - Works fine and creates the graphics
4) Davis Logger ---> VSPE ---> VVPro ---> WeatherLink - Fails and gives Loop errors

On TCPIP
5) DIYLogger ---> VVPro (no VPSE running)  - Fails and gives Loop errors
6) Davis Logger ---> VVPro (no VPSE running) - Fails and gives Loop errors

On steps 1 and 3 the logger was directly feeding WeatherLink. On steps 2 and 4 VPSE was running to provide comport emulation because multiple weather programs cannot all access the hardware comport without timeouts or conflicts, thus VPSE is needed.

On steps 5 and 6 I didn't run VPSE because the loggers were going through the TCIP side of VVPro and the comports were not needed. Also "Protect Console" in VVPro was not enabled and still resulted in the Loop error. Oh, and yes....we realize.....WeatherLink is out of date, VVPro is unsupported, why run more than one program....yada yada yada....heard it before.

To confirm the Network & Profile function is configured ok, untick the [Download Weather Station First], with WeatherLinkPC running the Profiles will create the config'd Template/Reports and images will be created.

Also depending on how one setups the profiles, there can be no need to [Download Weather Station First] for every profile.

I forgot to mention.....in all the scenarios the Download Weather Station First was not enabled. Also in VVPro the Protect Console was not enabled.

So you have the same setup I described working ? That is  datalogger ---> VSPE ---> VVPro ---> WeatherLink (Comport setup) ...or datalogger --> VVPro ---> Weatherlink (TCPIP setup).
I know that datalogger ---> Weatherlink directly works fine as in scenarios 1 and 3. My test setup shows this fails when VVPro is in the middle. So your setup with Weatherlink and VVPro generates the graphics ? What other settings are you using/not using ?

[Mattk]

Ok so the key thing here is data that is in the logger, the graph data comes from the logger/archive with or without downloading first. That quick test I did is an Envoy with NanoSD created to a simple local network drive.

Chief was using VSPE/VVPro as I do to run multiple programs and found the problem. He had brought a DIYLogger and the serial to USB cable I set up according to specs. It's not the problem because the Davis Logger does the same thing when WeathLink is combined with VVPro. The program runs fine, it's just when the Internet profile is set up the graphics are not generated and Loop errors are recorded. Weatherlink works fine when setup directly (see steps 1 and 3 in my post). The question remains... is there a setting for VVPro --> Weatherlink to generate the graphics in the internet settings ?
To diagnose the problem, use the same setup as in my post.

Garth---Thank you.  You have done a ton of work.

For anyone else-I do not have access to my station at school to do what he did.
Also, it is 65F in the server room and I have to wear a coat after a few hours.


This is a bit of a bummer.  I bought the extra console to make graphics AND we DO NOT run 2.4 at school for the newer consoles to connect to the computer.

I wondered if I put an old 2.4g stick on the computer--if it would connect to the console, but I believe it needs to go through a router.   (tell me if I am wrong)

Just have to wait for  Yerren to move up development of WDL. It needs a few more options.

Thanks again Garth.

If you just run Weatherlink straight to the logger/console and not use VVPro it will work. Without VVPro you won't be able to run multiple programs. What about using Weather Display for your graphics generation? ? It runs fine with VVPro. Then you can run multiple programs.
Just the Weatherlink program will be only useful to display and save data  and upload to Weatherlink.com website and app.

The Davis console/Envoys are RF (radio frequency) not WiFi. They need to connect to a computer/raspberry pi/netamo etc.via the datalogger, You would need a Weather Link Live (6100) to go wifi.

One thing I have lost track of is the need for VVPro. Are you wanting to run multiple programs ? Or would running the Weatherlink program only suffice ? or any other program like Weather Display work ? Do you need a computer running a weather program(s) and then uploading to a personal website, or would direct to a free site like Weatherlink.com work ? The app is free to your users and they would see your weather data but not in true real time.

I run VVPro with multiple programs because in the beginning I couldn't decide what weather program I wanted to use. So I started using VVPro and adding on to my collection of programs. Now it is up to WxSolutions, Cumulus, Weather Tracker, WeatherLink, Weather Display, Add-In Weather, and Virtual Weather Station. All running fine fine through VVPro and VPSE.  I haven't gotten around to CumulusMX yet.

I need to find how to run the WD dew point graph.

[chief-david]

I have sucked trying to get the jp graphs to work with the steel series gauges.

I .....   am not.....a programmer

[chief-david]

How about this.....someone here I trust.

Log into my web server and do some magic to get my steel series gauge graphs and jp graphs to work. I know I am missing something. I just cant get it.
