+## Entity exclude filter
+
+Optionally restrict which Home Assistant entities are synchronised into ioBroker.
+
+Each non-empty, non-comment line in the **Exclude patterns** field is a glob
+(only `*` is a wildcard and matches any sequence of characters, including `.`).
+Patterns are matched case-sensitively against the full `entity_id` (e.g.
+`switch.living_room`). An entity that matches any pattern is:
+
+- skipped when objects are created or updated (initial sync and re-syncs)
+- ignored when its state changes in HASS (no state writes triggered in ioBroker)
+
+Lines starting with `#` are treated as comments.
+
+Examples:
+
+```
+# Drop every entity whose name starts with `iob_`, regardless of domain:
+*.iob_*
+
+# Drop sensors only:
+sensor.iob_*
+```
+
+Tick **Verbose filter logging** to log every excluded `entity_id` individually
+during the first sync (requires adapter loglevel `info` or `debug`). Subsequent
+re-syncs only emit the aggregate count to keep the log clean.
+
+An empty pattern list leaves the adapter behaviour identical to previous versions.
