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

Currently, the integration only supports measuring download bandwidth. If you want to measure bandwidth metrics other than download such as ping and upload, utilize the integration.

Enabling this integration will automatically create the Sensor.

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


To add the integration to your Home Assistant instance, use this My button:


  • 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.
