myPWS1.11.1 - App Store

The app for PWS owners and 'Weather Underground' contributors, exclusively for iOS and WatchOS!

You own a weather station that submits measurement data to Wunderground.com (WeatherUnderground)? You want to get a quick overview, as well as detailed diagrams with the readings of your weather station and those of more than 250,000 other weather stations of the Wunderground network?

Then myPWS is exactly the right app for you! All you need is: your personal API key, which will be created in your personal account on Wunderground.com for you to retrieve.

Once you've configured access to Wunderground.com for myPWS by entering your API key, myPWS will let you view the latest readings from your weather station, as well as any other weather station registered on Wunderground.com. You can use an area map to search for near or far weather stations all over the world and have them displayed for detailed diagrams and current readings.

myPWS offers you extensive diagrams with the

. measured values ​​of the current and the previous day
. the last 7 days (per hour / per day)
. any day in the past*
. monthly data*
. yearly data*
. data of two PWS in one single comparison chart*
. combined data of one PWS in a single chart*
. wind direction chart*

Up to two different types of data can be displayed together in a diagram, e.g. to look at temperature and air pressure together in one graph.

Furthermore you can

. cache and export data via iCloud our email to your other devices on which you also use myPWS*. This saves data API calls which are limited to 1,500 per day through Wunderground.com via your API key
. add more than two stations to your station list*
. export diagram data via CSV, PDF or as graphics*
. email - export raw measurement data as provided by Underground

Please note: myPWS requires a Wunderground.com account and a PWS (Personal Weather Station) registered in your account. By registering a PWS you will receive an API key which is needed for the retrieval of data from the Wunderground network by myPWS. The access to PWS measurement data via the Wunderground data server depends on the availability of the WU infrastructure and the WU API services, which are not under the control of the manufacturers of the myPWS app.
