# Davis Binding v1
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 (opens new window) from Davis.
# Binding Configuration
The binding can be configured in the file services/davis.cfg.
Connection type must be specified as either serial (using the property 'port') or ip (using the property 'hostName'). These are mutually exclusive and both must not be simultaneously configured.
| Property | Default | Required | Description |
|---|---|---|---|
| port | Yes if serial communication | The serial port of the Weather station | |
| hostName | Yes if ip communication | HostName of the Weather station | |
| refresh | 10000 | No | The refresh interval (in milliseconds) |
| readResponseWaitTime | 200 | 1000 | No |
# Item Configuration
Item bindings should conform to this format:
davis="<value-key>"
The following table defines the allowable values for <value-key>.
