See the "user area" tab and "stroke alerts".
It would be good to have push notifications to mobiles as an option rather than e-mail though, it would (possibly) use less data and definitely be less clutter in my inbox.
I tried a little bit around with THINGSPEAK (https://thingspeak.com/) as a temporary workaround using ThingHTTP. Using ThingHttp it is possible to fetch specific data from a webpage like Blitzortung and "parse" it. I tried it with Firefox (embedded Firebug and Firepath) to extract the xpath. This information can be used to trigger a PROWL push notification.
Some basic information how to fetch data from a web-page can be found here: http://techiesms.com/blog/fetching-data-...pberry-pi/
My results were not very satisfying.
The ThingHTTP parser is not working well. I can parse some values but most of them not or I get a wrong result. The push notification with ThingHTTP is working well. I got a notification triggered with ThingHTTP on my iPad with installed PROWL App.
For those who are more experienced like me and interested here's my idea for a work-around until maybe in future a developer is willing to go a way like native support of PROWL or similar:
1. ThingHTTP fetches specific data from the Blitzortung webpage or from the SystemBlue server webpage
2. the data will be processed by a server like on a Raspberry Pi or with ThingSpeak Mathlab...
3. If a value is exceeded ThingHTTP will trigger PROWL (or a similar App) and a notification is pushed to a mobile phone
(4. or to trigger any other stuff like warning lamp in the living room if more and more lighning strikes are deteced in closer range, or or or...
