BigAssFan Binding

The BigAssFan binding is used to enable communication between openHAB and Big Ass Fans’ Haiku family of residential fans that implement the SenseME technology.


Fans are discovered dynamically. There is a single thing created for each fan connected to the network. Each thing has channels that allow control of the fan and the optional LED light, as well as to monitor the status of the fan. When the fan is controlled from the remote control, Wall Controller, or smartphone app, the openHAB items linked to the fan’s channels will be updated to reflect the fan’s status.

Device Discovery

The BigAssFan binding discovers Haiku fans on the network, and creates an inbox entry for each discovered device. Once added as a thing, the user can control the fan and optional LED light kit, similarly to how the fan is controlled using the remote, Wall Controller, or smartphone app.

Background discovery polls the network every few minutes for fans. Background discovery is enabled by default. To disable background discovery, add the following line to the conf/services/runtime.cfg file:


Thing Configuration

The fan’s IP address, MAC address, and name is set at time of discovery. However, in the event that any of this information changes, the fan’s configuration must be updated.

Manual Thing Creation

Fans can be manually created in the PaperUI or HABmin, or by placing a .things file in the conf/things directory. See example below.

Dimmer PorchFanSpeed                { channel="bigassfan:fan:20F85EDAA56A:fan-speed" }
Switch PorchFanAuto                 { channel="bigassfan:fan:20F85EDAA56A:fan-auto" }
Switch PorchFanWhoosh               { channel="bigassfan:fan:20F85EDAA56A:fan-whoosh" }
String PorchFanSmartmode            { channel="bigassfan:fan:20F85EDAA56A:fan-smartmode" }
Dimmer PorchFanSpeedMin             { channel="bigassfan:fan:20F85EDAA56A:fan-learn-minspeed" }
Dimmer PorchFanSpeedMax             { channel="bigassfan:fan:20F85EDAA56A:fan-learn-maxspeed" }

The following item definitions would be used to control the light.

Switch PorchFanLightPower           { channel="bigassfan:fan:20F85EDAA56A:light-power" }
Dimmer PorchFanLightLevel           { channel="bigassfan:fan:20F85EDAA56A:light-level" }
Switch PorchFanLightAuto            { channel="bigassfan:fan:20F85EDAA56A:light-auto" }
Switch PorchFanLightSmarter         { channel="bigassfan:fan:20F85EDAA56A:light-smarter" }
Dimmer PorchFanLightLevelMin        { channel="bigassfan:fan:20F85EDAA56A:light-level-min" }
Dimmer PorchFanLightLevelMax        { channel="bigassfan:fan:20F85EDAA56A:light-level-max" }
String PorchFanLightPresent         { channel="bigassfan:fan:20F85EDAA56A:light-present" }

The following readonly items are provided by the fan.

Switch PorchFanMotionSensor         { channel="bigassfan:fan:20F85EDAA56A:motion" }
DateTime PorchFanTime               { channel="bigassfan:fan:20F85EDAA56A:time" }

Wall Controller Items

Switch PorchControllerMotionSensor  { channel="bigassfan:controller:20F85ED87F01:motion" }
DateTime PorchControllerTime        { channel="bigassfan:controller:20F85ED87F01:time" }


This is an example of how to set up your sitemap.

Frame label="Control My BigAssFan" {
    Switch item=PorchFanPower label="Fan Power [%s]"
    Slider item=PorchFanSpeed label="Fan Speed [%s %%]"
    Switch item=PorchFanLightPower label="Light Power [%s]"
    Slider item=PorchFanLightSpeed label="Light Brightness [%s %%]"

Manual Thing Creation

Place a file named bigassfan.things in the conf/things directory. The file should contain lines formatted like this.

bigassfan:fan:20F85EDAA56A [ label="Porch Fan", ipAddress="", macAddress="20:F8:5E:DA:A5:6A" ]
