The Chowmain Big Ass Fans Driver for Control4 allows integration of the IP controllable Big Ass Fans and Big Ass Lights into Control4 allowing full 2 way multispeed fan and multi level lighting control over your home.

Integration into Control4 allows control from a single point using Control4's touchscreens, mobile applications, keypads, handheld remote controls and cloud based 4sight remote monitoring and control service. On top of that it exposes control over the Haiku products in the Control4 ecosystem to provide interaction from other devices in the home.

From turning off your fans and lights when you arm your security system to automatically turning them on when it detects you are at home and if the temperature is at an uncomfortable level integration provides you with so many different solutions to make your lifestyle that much easier.


  • Automatically find Lights and Fans on your network
  • Adjustable polling for updated feedback

Fan Features

  • Automatic naming of device upon binding
  • Assign Preset Speed (On speed when toggled)
  • Two way feedback – Speed, Device Name, Device MAC Address, Device IP Address
  • Programming Commands - Whoosh Mode, Fan Auto, Fan Direction, Smart Mode (Heating, Cooling, Off)

Light Features

  • Automatic naming of device upon binding
  • Auto mapped light levels (Control4 has 0-100 where Haiku has 0-16)
  • Support for Advanced Lighting Scenes
  • Two way feedback – Level, Device Name, Device MAC Address, Device IP Address
  • Programming Commands - Light Auto


Can you give us some examples of how we could use this driver? 

  • Integration with Control4 allows you to use control the Fans and Lights from any Control4 user interface including touchscreens, mobile devices, onscreen devices, keypads and 4sight.
  • Program your home to automatically turn off all lights and fans when you arm the security system.  Turn on fans if the temperature is high and you have just returned home.
  • Link lighting and fans to motion sensors to save energy in unoccupied rooms.
  • Tie the fan to your HVAC system to automatically switch between heating, cooling or off smart modes.  This assists with distribution of air based on the HVAC mode.

Which Big Ass Fan Products are supported by this driver?

At this time, the following products are supported:

  • Haiku (H and I Series)
  • Haiku L
  • Haiku Light
  • i6
  • es6

Future models may work with this driver in the future.  If its supported by the Big Ass Fans mobile app, it's probably supported by our driver.

Where is the Fan in Control4's interface?

Fan control is available from Control4's lighting page

How come the dimmer level changes slightly when i set a level?

Many light only have dim levels of 0-16, which may cause the level changes to vary

I notice that the driver automatically renames. What if i want to name it myself?

Adjust the Auto Rename Property on the fan.

How do i use whoosh, fan direction or the automatic settings?

These functions are programmed as one-way commands in the fan / light driver's programming commands. You should tie these into experience buttons, schedules or other event based programming.

What Control4 OS is required for this driver?

OS 3.3.0 or above is required for our Big Ass Fans V2 driver. For Legacy systems, V1 may still be used, but requires older firmware and supports limited hardware (Haiku only).

My Fans were working correctly in V1, however, the fans do not operate in V2

You must upgrade your mobile app from the original Haiku App to the new Big Ass fans app and update the firmware. V2 requires updated firmware for operation. V1 does not require updated firmware, but it does not support all of the features or hardware of V2.

I have functionality I want to use which isn't available as a command or binding

We expose lots of functionality as variables which you can modify. If there are variables which you can't write to, or if you want functionality which is better handled in another way, let us know.

Do you offer showroom discounts?

This is a Major update which of the Big Ass Fans Driver, which introduces our new V2 driver suite which supports Big Ass Fans new 3.0 firmware and Big Ass Fans app. All Big Ass Devices must be upgraded to the new 3.0 firmware to operate using the mobile app (V2 does not support the legacy SenseMe firmware). Our new driver suite requires OS 3.3 for lighting to operate correctly.

Please note, this is a major rewrite. After upgrading device firmware to V3.0, you must delete the old drivers and replace them with the rewritten V2 drivers.

Some benefits of the new drivers include:

  • Driver is no longer limited only to Haiku, but a much wider range of Big Ass Fans devices
  • OS 3.3 CCT / White Temperature Light ColorWheel Control
  • Occupancy Sensor Support
  • Huge range of variables for feedback. And various read-write variables for advanced users
  • Compatibility with the new V3.X firmware

Thanks to all our beta testers for their feedback and feedback including:

  • Cameron Etezadi
  • David Estabrook
