LiquidCheck Binding

This binding is for the Liquid-Check device from SI-Elektronik GmbH which can be used to measure level and content of tanks.

Supported Things

liquidCheckDevice:

The Liquid-Check device in Hardwareversion B and Firmwareversion 1.60 has been tested and is working. You can access the measured data, raw data, the settings as properties and command a measurement.

Discovery

This binding discovers the devices via a ping and request method. It uses every Ethernet/WLAN interface that is connected to the openHAB server. Therefore the discovery has to be manually triggered.

Thing Configuration

You only need to set the IP address of the device or use the discovery method. If the maximum content has not been set the fill-indicator channel will not contain valid values.

liquidCheckDevice Thing Configuration

Name	Type	Description	Default	Required	Advanced
hostname	text	Hostname or IP address of the device	N/A	yes	no
