It's possible to filter events by change type. Use the `--allowed-types=TYPE1,TYPE2,...` command line parameter to do that. If that parameter is not provided, then all change types are allowed, otherwise only the provided ones will be used for notifications.
### Filtering events by index (I guess "zone", but I'm not sure)
Use the `--allowed-indexes=1,2,3,...` command line parameter to set the list of allowed indexes (of course provide your own list instead of `1,2,3,...`). If that parameter is not provided, then all indexes are allowed; otherwise the notification is sent for all indexes.
