+## Filtering
+
+There is basic filtering implemented (this can be changed during development)
+
+The following files are used:
+
+match_text.txt
+match_capcodes.txt
+ignore_text.txt
+ignore_capcodes.txt
+
+
+Type of filtering is ignored if a file is empty or only has commented line in it (leading with a #)
+
+The syntax for match_text and ignore_text is using fnmatch.

+You can get message events on your mobile device(s) by using a notify event, for example like this:
+```
+automation:
+  - alias: "Melding P2000 Bericht"
+    trigger:
+      platform: state
+      entity_id: sensor.p2000
+    action:
+      service: notify.telegram
+      data_template:
+        message: >
+          {{ states.sensor.p2000.state + "\n" + states.sensor.p2000.attributes.disciplines }}
+```
