Once we have this caching system in place, we will add historical API to our Weather API and allow it to properly get the data needed when it’s missing or use the cached data when appropriate. We just upgraded our OWM account to provide better forecast data and we are planning on implementing a caching system so we can lower the number of redundant calls to the API (both the app and the device are querying the same location for the same data now). Other weather adjustment methods, such as Zimmerman, can work with WU PWS.I agree with you there is a discrepancy in the quality of data we have now versus with WUnderground. Note that at the time of this writing, if you choose PWS as data source, you cannot choose ET as the weather adjustment method, because WU PWS data lacks 'solar radiation' parameter required by ET. It will automatically record the PWS station name. You can select any of those blue dots, and submit. Next, go to Edit Options -> System, click on Location, it should show you nearby PWS stations in blue dots. Once you have the WU API key, you can input that in Edit Options -> Advanced. It's typically a 32-character long string.įrom firmware 2.1.9, support for using WU PWS as data source has been added. Regardless of how many devices you have, you will only have one key. Once you have a PWS device, you can go to the ' API Keys' tab to create a WU API key. Please note that unless if you have a physical PWS that you own, this particular PWS will not have any valid data, so do NOT use this particular PWS for getting weather data. Enter your address, and from the list of available devices, you can select any (e.g. You do not actually need to own a device physically.

Here you will need to add a PWS (Personal Weather Station) device. Log in to WU, then click on ' My Profile' at the top-right side of the screen, click on the ' My Device' tab. We do not know how long this will be valid till they make changes again, so please use the instructions below at your own discretion. Below we document the current way (as of July 16, 2019) to acquire a WU API key and PWS station name. From firmware 2.1.9, we have added back support for WU PWS (Personal Weather Station). At the moment of this writing, the OpenSprinkler weather service by default uses DarkSky API and no longer depends on WU. Update : between 2018 to 2019, Weather Underground (WU) was acquired by IBM, changing their API service and the process to apply for an API key.
