+### {% linkable_title Brightness without on commands %}
+
+To enable a light that sends only brightness topics to turn it on, add the following to your `configuration.yaml` file. The `command_topic` is only used to send an off command in this case:
+
+```yaml
+# Example configuration.yml entry
+light:
+  - platform: mqtt
+    name: "Brightness light"
+    state_topic: "office/light/status"
+    command_topic: "office/light/switch"
+    payload_off: "OFF"
+    brightness_state_topic: 'office/rgb1/light/brightness'
+    brightness_command_topic: 'office/rgb1/light/brightness/set'
+    on_command_type: 'brightness'
+```

 - A [basic example](https://github.com/mertenats/open-home-automation/tree/master/ha_mqtt_light) using a nodeMCU board (ESP8266) to control its built-in LED (on/off).
