BigAssFan Binding

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

Overview

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

Device Discovery

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

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

discovery.bigassfan:background=false

Thing Configuration

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

Manual Thing Creation

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