Big Ass Fans

Integrates Big Ass Fans devices into Home Assistant.

Supported devices

  • Haiku Fans with 3.0 firmware and later (Legacy SenseME firmware not supported)
  • Discontinued Haiku Lights with 3.0 firmware and later (Legacy SenseME firmware not supported)
  • i6 Fans



For devices that support Auto Comfort, a climate entity allows adjusting the target temperature.


Adjusting the minimum and maximum speed for devices that support Auto Comfort is available.

Timeouts for returning to auto mode or turning back off after motion use a unit of seconds.


If the device supports it, the integration creates the following sensors, which receive push updates:

  • Temperature
  • Humidity

Additional diagnostic sensors are available, which generally do not receive push updates that need to be enabled in the UI if desired.


The integration represents Whoosh mode as a switch for fans. When Whoosh is enabled, the fan will latch to the current speed and vary the speed from the latch point.


Adding Big Ass Fans to your Home Assistant instance can be done via the user interface, by using this My button:

Big Ass Fans can be auto-discovered by Home Assistant. If an instance was found, it will be shown as “Discovered”, which you can select to set it up right away.
