At least no European Netatmo station seemed to be anymore listed in their Wundermap.

They have also stopped pulling data from Netatmo weather stations since the end of the day of 2. A web search showed that they have not only discontinued their free API key. I ‘m still interested in a working Zimmerman algorithm and investigated a little bit more the Weather Underground changes. The bad news is that it relies on WU, which seems to be not working anymore. I also bought Netatmo and OpenSprinkler as these combination seems to be perfect for garden watering. However a direct interface to Netatmo might be the better solution. There exists the possibility to set the Open Sprinkler rain delay time by API commands forwarded from IFTTT and apilio.io applets. I like the idea of having at least the output of the Netatmo rain gauge included in the weather algorithm. This means their might be a heavy rainfall a few kilometers away but no rainfall at all at my home location. We have some afternoon thunderstorm at the moment and they are very local to our area. It would be also nice to have some information about the weather station providing the data. Is this a general OpenSprinkler firmware or app issue, if the Zimmerman weather algorithm is based on OWM? There is also no weather logo visible at the App’s front page. I always get the message that an API key will be needed, if I click on the Weather Diagnostics button. It is strange that there is no possibility to see the weather data used for the Zimmerman calculation anymore. I think the weather algorithm is working in some way, but I still can’t see if there is any precipitation value from yesterday’s rainfall measurement included. For the time being we have had a sunny day and the water level was hourly updated to 72% during the day. Following the information above, I have deleted the WU key in order to use the OWM data for the Zimmerman weather algorithm.
