+### Activating a preset
+
+Activating a preset is an easy way to set a WLED light to a specific
+configuration. Here is an example service call to set a WLED light 
+to a preset called My Preset:
+
+```yaml
+- service: light.turn_on
+  target:
+    entity_id: light.wled
+- service: select.select_option
+  target:
+    entity_id: select.wled_preset
+  data:
+    option: "My Preset"
+```
+
+### Automation Using Specific Palette Name
+
+An automation to turn on a WLED light and select a specific palette and
+set intensity, and speed can be created by first calling the `light.turn_on`
+service, then calling the `select.select_option` service to select the
+palette, then call the `number.set_value` service to set the intensity
+and again to set the speed. 
+
+Here is an example of all of these put together into an automation:
+
+```yaml
+- alias: "Turn on WLED rain effect when weather changes to rainy"
+  trigger:
+    - platform: state
+      entity_id: sensor.weather_condition
+      to: "rainy"
+  action:
+    - service: light.turn_on
+      target:
+        entity_id: light.wled
+      data:
+        effect: "Rain"
+    - service: select.select_option
+      target:
+        entity_id: select.wled_color_palette
+      data:
+        option: "Breeze"
+    - service: number.set_value
+      target:
+        entity_id: number.wled_intensity
+      data:
+        value: 200
+    - service: number.set_value
+      target:
+        entity_id: number.wled_speed
+      data:
+        value: 255
+```
