# Davis Binding

The openHAB Davis binding supports reading data from Davis weather stations.  Most Davis weather stations should be supported.

The binding is based on the [Serial Communication Reference Manual](http://www.google.at/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0CCQQFjAA&url=http%3A%2F%2Fwww.davisnet.com%2Fsupport%2Fweather%2Fdownload%2FVantageSerialProtocolDocs_v261.pdf&ei=yns1VLO9B9Pe7Ab9hYDgDQ&usg=AFQjCNEUP_O6jjV3tHaxc7_faaLKWAtw2g&sig2=0YuJy45Qmk76RlffOqayuA&bvm=bv.76943099,d.ZGU) from Davis.


## Binding Configuration

The binding can be configured in the file `services/davis.cfg`.

| Property | Default | Required | Description                            |
|----------|---------|:--------:|----------------------------------------|
| port     |         | Yes      | The serial port of the Weather station |
| refresh  | 10000   | No       | The refresh interval (in milliseconds) |


## Item Configuration

Item bindings should conform to this format:

    davis="<value-key>"

The following table defines the allowable values for `<value-key>`.
