+Use your `Meraki AP` as device tracker. Note that Meraki will see all devices, not only connected to the network.
+Follow instructions [here](https://meraki.cisco.com/technologies/location-analytics-api) how to enable Location Analytics. 
+
+After you configure access to the Meraki CMX API, add the following to your `configuration.yaml` file:
+
+```yaml
+# Example configuration.yaml entry
+device_tracker:
+  - platform: meraki
+    secret: your_secert
+    validator: meraki_validator
+```
+
