# OneBusAway Binding

OneBusAway (opens new window) is an open source, real-time, transit-information service. This binding allows you to get events based on transit arrival and departures, so you can create rules to do something based on that data.

# Preparation

You will need to obtain an API key from the transit provider you want to load data from. Different providers of the service have different policies, so you will have to figure this part out for each deployment (opens new window).

# Supported Things

This binding supports route arrival and departure times for all stops provided from a OneBusAway deployment.

# Binding Configuration

The following configuration options are available for the API binding:

Parameter Name Description Required
apiKey API Key The API key given to you by a transit provider for their deployment. yes
apiServer API Server The domain name of the deployment to talk to, e.g. api.pugetsound.onebusaway.org. yes

The following configuration options are available for the Stop binding (which requires an API binding):

Parameter Name Description Required
stopId Stop ID The OneBusAway ID of the stop to obtain data for, e.g. 1_26860. yes
interval Update Interval The number of seconds between updates. no

# Thing Configuration

The following configuration options are available for a Route (which requires a Stop binding):

Parameter Name Description Required
routeId Route ID The OneBusAway ID of the route to obtain data for, e.g. 1_102574. yes

# Channels

The Route Thing supports the following state channels:

Channel Type ID Channel Kind Item Type Description
arrival state DateTime The arrival time of a Route at a Stop.
departure state DateTime The departure time of a Route at a Stop.
update state DateTime The last time this data was updated (per the data provider, not the last time openHAB updated the data).
arrivalDeparture trigger DateTime Triggered when a Route arrives or departs a Stop.

# Channel Configurations

The arrival, departure, and arrivalDeparture channels can be configured with an offset specifying the number of seconds to move an event back in time.

# Full Example

Here is an example of a configuration for a bus stop in Seattle, WA, USA that has three routes configured.
