# BigAssFan Binding

The [BigAssFan](https://www.bigassfans.com/) 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, lights and controllers are discovered dynamically.
There is a single thing created for each fan, light, or controller that's connected to the local WiFi 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.

## Supported Things

The binding currently supports the following devices.

| Thing       | ID          |                    |
|-------------|-------------|--------------------|
| Fan         | fan         | BigAssFan consisting of fan and integrated LED light |
| Light       | light       | Standalone LED light |
| Controller  | controller  | Fan wall controller |

## Thing Configuration

| Parameter    | Parameter ID  | Required/Optional | Description |
|--------------|---------------|-------------------|-------------|
| Label        | label         | Required          | Label given to device in the Haiku Smartphone app. |
| IP Address   | ipAddress     | Required          | IP address of the device. |
| MAC Address  | macAddress    | Required          | MAC address of the device. |

In the event that any of this information is changed on the device, the thing configuration must be updated manually, as it cannot be determined automatically by the binding.

### Manual Thing Creation

Fan and light things can be manually created using the *UI*, or by placing a *.things* file in the *conf/things* directory.
See example below.

## 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:

```text
discovery.bigassfan:background=false
```

## Channels
