Fast.com	How to integrate Fast.com within Home Assistant.	Sensor System monitor	0.88	Cloud Polling	true	@rohankapoorcom @erwindouna	fastdotcom	diagnostics sensor	integration

The fastdotcom integration uses the Fast.com web service to measure network bandwidth performance.

{% note %} Currently, the Fast.com integration only supports measuring download bandwidth. If you want to measure bandwidth metrics other than download such as ping and upload, utilize the Speedtest.net integration. {% endnote %}

Enabling this integration will automatically create the Fast.com Sensor.

By default, a speed test will be run every hour. The user can manually run a speed test via the homeassistant.update_entity action.

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.
