I may be missing this - but the json and xml files do not have/report THSW index.  I do see heat index.  Anyone know why this is not passed?

Because current THSW index is not available.

Is this by design or some limitation? I find THSW very useful.

I use WL2.0 And wanted to build a custom webpage and was hoping to show THSW.

In WL2.0 the only place to get THSW is in the chart area. They do not show it on the bulletin page, the mobilize page or the mobilize app. It does in fact show it in their weatherlink app - although update frequency seems once an hour at best.

Whatís interesting is that for mobilize (both app and web) the field is there but it only populates ď- -ď

So it seems they have the data since itís show accurately in the chart (and my VP2 console) and I opened a ticket with them for the app not populating the field.

I hope you are successful - but this link from 8 years ago says I had been asking for that for over 3 years....

THW may be available, along with "Daily High THSW".  (I'm just going by the available tags in WeatherLink software)

I find THSW  very useful for those days I want the air conditioner on and the wife doesn't.  I put it up on the Kitchen Console and we have coolness in the summer.
I do  believe that Weatherdisplay has those tags. 

However, neither does Weatherlink 1.0; Weatherlink 2.0 or the app for whatever platform you use, have that sent or calculated.   I suspect someone could dig out the formula and write a script that has that calculation.  I do see that the WL 2.0 phone app has that.  Perhaps the best route would be to contact Davisnet and ask them to put that tag out there.   They did say that the desktop (computer) based software was no longer to be supported.

To be accurate, Davis have intimated that local Weatherlink is not likely to be significantly developed any further, which is something different from not being supported. So if there's anything new with Windows, USB drivers etc that is incompatible with WL603 then a new WL version with fixes is likely to appear. Indeed I think there might be one pending to deal with some potential issue, but can't quite remember what.

This is what I found for WL 2.0  Not sure if it is only for pro or not, but on their user site there is a place to generate the API for your WL2.0

Hello,

I am a French developer. I created Oras, a free application that retrieves data sent by Weatherlink dataloggers. For this, Oras retrieves the data from the website api.weatherlink.com

Basically, this software is a request from my brother (https://www.facebook.com/MeteoVaroise/), who needed to recover and export this data. I make it available for free if it can be used by others.

The development is in stand-by for the moment, but other functionalities will be able to see the day according to the returns of the users (in particular, other possibilities of export of the recovered data).

For the moment it is not yet translated into English, only in French.

You can download Oras here : http://anthonylaurito.fr/devbox/

Thank you
Anthony

Hi All, I have been using the WL api to get data from stations reporting every 1h, but sometimes the station has no connection so I miss data that I am storing my side.

I see that missed data was transmitted in WL, Since API only shows most recent value not history I cannot "fill" missed values without going to download data and process

is there an API endpoint to get history like querying ?from=20180601&to=20180602 for example ?

regards

AFAIK, they've not announced a historical retrieval function in the API .. 5/18/2018 doc here https://www.weatherlink.com/static/docs/APIdocumentation.pdf

It's in binary rather than in JSON or XML format, but of course the web download protocol (explained in the Serial API document) does just this - ie retrieves all summary/archive data over a specified date range from wl.com. For anyone wanted to maintain an independent database of weather data it's probably a better approach than trying to capture all the individual real-time readings.

Download the Serial Tech Ref document from the Davis support site and look at the Web Download section.

Although this document largely applies to downloads direct from the logger, the web download section deal with downloads from wl.com. Remember if you're on the 2.0 platform then you need the DID in place of user name plus the account password.
