 You need to [enable telnet](https://www.asus.com/support/faq/1005449/) on your router if you choose to use `protocol: telnet`.

+### {% linkable_title Example Sensor Configuration %}
+
+To enable ASUSWRT sensors as part of your installation, reference the following example configuration:
+
+```yaml
+# Example configuration.yaml entry
+asuswrt:
+  host: YOUR_ROUTER_IP
+  username: YOUR_ADMIN_USERNAME
+  ssh_key: /config/id_rsa
+  sensors:
+    - upload
+    - download
+    - upload_speed
+    - download_speed
+```
+
+The example above, creates the following sensors:
+
+* sensor.asuswrt_download (unit_of_measurement: Gigabyte - *Daily accumulation*)
+* sensor.asuswrt_download_speed (unit_of_measurement: Mbit/s)
+* sensor.asuswrt_upload (unit_of_measurement: Gigabyte - *Daily accumulation*)
+* sensor.asuswrt_upload_speed (unit_of_measurement: Mbit/s)
