The `fastdotcom` integration uses the [Fast.com](https://fast.com/) web service to measure network bandwidth performance.
<div class='note'>
Currently, the Fast.com integration only supports measuring download bandwidth.
If you want to measure bandwidth metrics other then download such as ping and upload, utilize the [Speedtest.net](/integrations/speedtestdotnet) integration.
</div>
Enabling this integration will automatically create the Fast.com Sensor.
By default, a speed test will be run every hour. The user can change the update frequency in the configuration by defining the `scan_interval` for a speed test to run.
## Configuration
To add Fast.com to your installation, add the following to your `configuration.yaml` file:
Once per hour, on the hour (default):
```yaml
fastdotcom:
```
Every half hour of every day:
```yaml
fastdotcom:
scan_interval:
minutes: 30
```
{% configuration %}
scan_interval:
description: "Minimum time interval between updates. Supported formats: `scan_interval: 'HH:MM:SS'`, `scan_interval: 'HH:MM'` and Time period dictionary (see example below)."
required: false
default: 60 minutes
type: time
manual:
description: Turn manual mode on or off. Manual mode will disable scheduled speedtests.
required: false
default: false
type: boolean
{% endconfiguration %}
### Time period dictionary example
```yaml
scan_interval:
# At least one of these must be specified:
days: 0
hours: 0
minutes: 3
seconds: 30
milliseconds: 0
```
## Service
Once loaded, the `fastdotcom` integration will expose a service (`fastdotcom.speedtest`) that can be called to run a Fast.com speed test on demand. This service takes no parameters. This can be useful if you have enabled manual mode.
```yaml
action:
service: fastdotcom.speedtest
```
## Notes
- When running on Raspberry Pi 3 or older, the maximum speed is limited by its 100 Mbit/s LAN adapter.
- The sensor will return the maximum measured speed during a 15-second test.
- Speed tests consume data depending on your internet speed, make sure to consider this if your internet connection has limited bandwidth.
