# Ambient Weather Binding
The Ambient Weather binding integrates weather station data that's stored on the Ambient Weather online service. The binding uses Ambient Weather's real-time API, so updates from weather stations are delivered to the binding in near real-time.
# Supported Things
The binding currently supports weather data from these weather stations.
| Thing | ID |
|---|---|
| Account | bridge |
| WS-0900-IP | ws0900ip |
| WS-1400-IP / WS-1401-IP | ws1400ip |
| WS-2902A / WS2902C | ws2902a |
| WS-2902B | ws2902b |
| WS-8482 | ws8482 |
| WS-0265 | ws0265 |
Other stations can be added relatively easily with changes in just several places in the source code.
# Discovery
Automatic discovery is currently not supported due to the lack of weather station model information in the Ambient Weather API.

# How To Add Another Weather Station Type
Adding support for a new weather station type involves changes to the source code in just a few places.
# Add a New Thing Type in AmbientWeatherBindingConstants.java
Define a new ThingTypeUID for the new station and add it to the SUPPORTED_THING_TYPES_UIDS Collection.
Add a channel group for the new station.
# Create OH-INF/thing/<station-model>.xml
Add thing type and channel group specific to the data elements supported by this weather station. Modeling this after an existing thing type that shares many of the channels is the easiest starting point. You can determine the weather data elements returned for the weather station by putting the binding into debug mode and reviewing the JSON object returned by the Ambient Weather API.
# Create Processor Class <StationModel>Processor
Add a class in org.openhab.binding.ambientweather.internal.processor that defines the channels supported by this station type.
Add the following two methods.
Again, the easiest approach is to model this class after a class for a similar weather station type.
# Method: processInfoUpdate
Updates the channels for station name and location.
# Method: processWeatherData
Updates channels for weather data.
# Update ProcessorFactory.java
Add new Processor class definition to ProcessorFactory.java, and add a new case to the switch statement to return the new processor.
