Weather station and OpenSprinkler

Since the firmware update to 2.1.9, it is now possible for you to connect your weather station - provided it has online access to the Weather Subgroup (Wunderground) - to your OpenSprinkler. This gives you the best weather control as real weather data from your garden is used. The WU symbol on the packaging indicates corresponding capability.

This is how it works:

1. Register your weather station http://www.wunderground.com, also consult the instructions for your weather station
2. Now click on http://www.wunderground.com At the top right click on “My Profile” and then on “My Devices”.
3. Your weather station should now appear. Now click on “API Key”.
4. Then click “Show Key”. Your API key should now appear here. Press “Copy to Clipboard.”
5. Next, start the OpenSprinkler APP or go to the web interface of your OpenSprinkler.
6. Check that you have firmware 2.1.9 or greater using the menu at the top left, then “About”.
7. Click “Edit options” at the bottom right and then click “Advanced”
8. Now insert the API key from 4. and press verify.
9. If the indicator is green, then the API key has been accepted.
10. Immediately afterwards, click on “System” and “Location”.
11. All nearby weather stations now appear on the map (blue markings). Select your weather station.
12. Click Save. Complete. From now on, OpenSprinkler receives the weather data from your station.

Attention: Only the “Zimmermann” method works with your own weather station! Evapotranspiration doesn't work here. This is because “solar radiation” is an important calculation factor in this method, but the service or most weather stations do not provide this value.
