-The `mqtt` device tracker platform allows you to define new device_trackers through [manual YAML configuration](#yaml-configuration) in `configuration.yaml` and also to automatically discover device_trackers through a [discovery schema](#discovery-schema) using the MQTT Discovery protocol.

+## Configuration
 
 To use this device tracker in your installation, add the following to your `configuration.yaml` file:
 
 ```yaml
 # Example configuration.yaml entry
+mqtt:
+  device_tracker:
+  - name: "annetherese_n4"
+    state_topic: "location/annetherese"
+  - name: "paulus_oneplus"
+    state_topic: "location/paulus"
+```
+
+{% details "Previous configuration format" %}
+
+The configuration format of manual configured MQTT items has changed.
+The old format that places configurations under the `switch` platform key
+should no longer be used and is deprecated.
+
+The above example shows the new and modern way,
+this is the previous/old example and deprecated configuration schema:
+
+```yaml
 device_tracker:
   - platform: mqtt
     devices:
       paulus_oneplus: "location/paulus"
       annetherese_n4: "location/annetherese"
 ```
 
+To set the state of the device_tracker then you need to publish a JSON message to the topic (e.g., via mqtt.publish service). As an example, the following JSON message would set the `paulus_oneplus` device_tracker to `home`:
+
+```json
+{
+  "topic": "location/paulus",
+  "payload": "home"

-## Discovery Schema
-
-MQTT device_trackers are also supported through [MQTT discovery](/docs/mqtt/discovery/). This is different to the YAML configuration from above. Here, the device_tracker can be created via a discovery topic that follows the following topic name convention: `<discovery_prefix>/device_tracker/[<node_id>/]<object_id>/config` and the JSON message content of a specific format as defined below.
