Defining Feeds, the intervall of caching is set to 5 minutes. This can be reduced to 30 seconds.
But what is the impact of this intervall? I assumed, that the data in the MashApp are refreshed after 30 seconds. This doesn't happen in my MashApp.
Can I automatic refresh the MashApp, when the data basis changes? Where do I have to change the settings in MashApp.

MashZone never reads data sources on its own. Its triggered by users viewing a MashApp or when debugging a data feed only.
So when a data feed is evaluated by the MashZone server the data sources must be read. When requesting data from the data sources a cache might be consulted first. The interval you set to 30sec results in this:
- data source is requested the first time
- data source is read
- result is stored in the cache and lives there for 30sec (or whatever you specified)
So any subsequent request during the next 30sec will receive its result from cache. After the interval the cache has expired and the data source is read again.
