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.

Overview

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:

org.openhab.binding.bigassfan.discovery.BigAssFanDiscoveryService:backgroundDiscovery.enabled=false

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.

Channels

The following channels are supported:

All devices support some of the following channels:
