+- Home Assistant services
+- Other automations

+## Example: Light Switch
+
+A typical four-button switch could be configured like this:
+
+| Button | Press | Hold | Release |
+|---|---|---|---|
+| Button 1 | Lights ON | Brightness up | Stop |
+| Button 2 | Lights OFF | Brightness down | Stop |
+| Button 3 | Scene ON | Dim | Stop |
+| Button 4 | Scene OFF | Dim | Stop |
+
+This allows a single EnOcean switch to provide a large number of functions.
+
+## Example: MQTT Flow
+
+For a button press, Zigbee2MQTT might publish:
+
+```text
+Topic:
+zigbee2mqtt/Livingroom_Switch/action
+
+Payload:
+press_1
+```
+The blueprint receives the MQTT message and identifies:
+```text
+Controller:
+Livingroom_Switch
+
+Command:
+press_1
+```
+The blueprint then waits for the configured hold delay to determine whether the event is a short press or a hold.
+
+## Event Processing
+
+The general processing logic is:
+
+```text
+                         MQTT Event
+                              │
+                              ▼
+                     Check controller
+                              │
+                              ▼
+                       Check command
+                              │
+                    ┌─────────┴─────────┐
