+
+The `speedtest` sensor component uses the [Speedtest.net](https://speedtest.net/) web service to measure network bandwidth performance.
+
+By default, it will run every hour on the hour.  The user can change the update frequency in the config by defining the minute, hour, and day for speedtest to run.
+
+To add speedtest.net sensors to your installation, add the following to your `configuration.yaml` file:
+
+Once per hour, on the hour (default):
+```yaml
+sensor:
+  platform: speedtest
+  monitored_conditions:
+    - ping
+    - download
+    - upload
+```
+
+More examples:
+
+Every half hour of every day:
+```yaml
+sensor:
+  platform: speedtest
+  minute:
+    - 0
+    - 30
+  monitored_conditions:
+    - ping
+    - download
+    - upload
+```
+
+Everyday at 12:30AM, 6:30AM, 12:30PM, 6:30PM:
+```yaml
+sensor:
+  platform: speedtest
+  minute: 30
+  hour:
+    - 0
+    - 6
+    - 12
+    - 18
+  monitored_conditions:
+    - ping
+    - download
+    - upload
+```
+
+Configuration variables:
+
+- **monitored_conditions** array (*Required*): Conditions to display in the frontend.
+  - **ping**: A human-readable text summary.
+  - **download**: The type of precipitation occurring.
+  - **upload**: The average expected intensity of precipitation occurring.
+  - **ozone**: The columnar density of total atmospheric ozone in Dobson.
+- **minute** (*Optional*): Specify the minute(s) of the hour to schedule the speedtest. Use a list for multiple entries. Default is 0.
+- **hour** (*Optional*): Specify the hour(s) of the day to schedule the speedtest. Use a list for multiple entries. Default is None.
+- **day** (*Optional*): Specify the day(s) of the month to schedule the speedtest. Use a list for multiple entries. Default is None.
