# 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>.
