+## Troubleshooting
+### Button does not trigger anything
+
+Check that the configured controller name matches the Zigbee2MQTT device name.
+
+For example:
+```text
+Zigbee2MQTT:
+Livingroom_Switch
+```
+must be entered as:
+```text
+Livingroom_Switch
+```
+Also verify that the MQTT base topic is correct.
+
+### Press works but Hold does not
+
+Check the Hold delay setting.
+
+The default is:
+```text
+500 ms
+```
+Try lowering the value if the switch does not reliably detect long presses.
+
+For PTM216Z devices, make sure:
+```text
+PTM216Z: ON
+```
+and that the required Text Helper has been selected.
+
+### Release action does not work
+
+The release action is specifically used for a release after a long press.
+
+For example, a short press:
+```text
+press_1 → release_1
+```
+will trigger:
+```text
+Button 1 Pressed
+```
+A long press:
+```text
+press_1
+    ↓
+Hold delay exceeded
+    ↓
+Button 1 Held
+    ↓
+release_1
+```
+will trigger:
+```text
+Button 1 Released
+```
+
+## Notes
+
+The blueprint uses MQTT topics generated by Zigbee2MQTT and filters events based on the configured controller name.
+
+The MQTT topic structure is:
+```text
+<base_topic>/<controller>/action
+```
+The default base topic is:
+```text
+zigbee2mqtt
+```
