Davis WeatherLink upgrade to 2.0

During summer 2018 Davis are updating WeatherLink to 2.0 (WL2). So if You have registered devices before 2017-11-28 You must migrate.

This update is changing their website, as shown in picture, and API.

Their API documentation is found here

The following information is sent out in 2018-06 to users who still haven't upgraded to WL2

Davis weather station, WeatherLink, PHP

Updated 2021-12-05 !

In the harbour we are using a Davis weather station, Vantage Pro2, as our PWS(Private Weather Station).

If you like to display the data, online on the web, you can use the Davis service, Weatherlink(WL) where you register an account. 

Another way is to retrieve the weather data as XML or JSON, from the Weatherlink web-site, and use it in your own application (open source!).

Another approach with NodeRed could be find here.

Install Weather34 with WeatherLink

Updated 2025-01-09 PHP 8.2 !

If You want Your Private Weather Station(PWS) Davis Vantage Pro2, or other Davis products that use WeatherLink, to provide data for the template we use at Domstens Båtklubb just follow the instructions below. 

This is made without additional software such as Cumulus, Weather display or the Meteobridge product.

This application is updated !!, to use the v2 API. Check  this post !!

WeatherLink weather template, v2 API

I have written a post with the same subject before, also using NodeRed(NR), but this post is using the latest WeatherLink v2 API instead of the v1 API. 

The v2 API supports more devices and now also including the old ones.

If You want a more advanced weather site this is a very nice one coded in PHP also using the v2 API.

WeatherLink weather template

Updated 2022-02-21 !

If You are interested in building Your own weathersite with information from Davis Weatherlink(DWL), and don't are a skilled programmer I can really recommend Node-Red(NR). In this post I give an example how to start with the NR dashboard GUI and DWL V1 API.

!! Please note new version with the latest v2 API !!

If You want a more advanced weather site/template this is a very nice one coded in PHP.

Install Weather34 with WeatherLink, v2 API

Updated 2025-01-08 OK PHP 8.2 !

This post is an update from a former post which handles on how to set up a weather WEB-site with data from Davis Weather Link(WL) but here adapted to the latest WL API v2.

Any product that reports weather data to WL can be used as a source for this weather template.

This is made without additional software such as Cumulus, Weather display or the Meteobridge product.

Weather34 install at WEB hotel

Updated 2019-04-01 !

Prerequisites is listed in the beginning of the post for installation on Raspberry Pi(RPi)

You will find migration information, from WeatherLink 1.0 to WeatherLink 2.0, in this post

Weather34 & WeatherLink w/o cronjob

Running Weather 34, W34, using my setup, the program "cumulusdata.php" is fetching data from Davis Weatherlink(WL), and are writing the data to a file, type Cumulus. The old way was to fetch the data via a scheduled cronjob. 

Doing a small change to "windspeeddirection.php", "updater.php" , and using the latest version of "cumulusdata.php", will do the update with the built in W34 refresh routine instead of cron job.

Thanks to Ken who gave me the hint.

Mac install Apache/PHP WEB-server

Updated 2019-01-07 

!! Note !! Before Monterey !! 

As a part of one of my projects, the ultimate Weather site ?? Weather34(W34), I needed a WEB-host with PHP and started to use a Raspberry Pi.

In this post You will get some short install tips on Apache with PHP on a Mac with Mojave, macOS 10.14.x, and at the end of the post the W34 installation is done.

Davis PWS linked to pwsweather.com

If you are using Davis Personal/Professional weather stations(PWS) you will get a nice dashboard when you link your PWS to the Davis weatherlink(WL) site.

What you probably really miss is a forecast displayed together with your PWS data. The picture is showing a part of the dashboard at pwsweather.com(PW) after you have linked your PWS to the site.

An add on is that you via API:s can get both the current weather, forecast and other data free of charge, via the aerisweather.com(AW) site.

This post will handle the setup and also a Node-Red dashboard interfacing the aeris API.
