Developer: Mauro Cicolella
This plugin reads values from an ethernet thermometer by HW-group.com. You can connect up to two sensors of temperature and humidity. Indoor/outdoor sensors are available. Even temperature sensor with flat cable for temperature monitoring in the fridges. More details at http://www.hw-group.com/products/HWg-STE/STE_ip_temperature_sensor_en.html
It works sending periodically SNMP (Simple Network Management Protocol) request to the device using the OID (Object Identifier) specified by the manufacturer (http://ste.hwg.cz/HWg-STE_OID.txt).
All the configuration parameters are included in the hwgste-manifest.xml file. You can use it without any changes.
Each thermometer data are included in a
<tuple></tuple> block where you need to specify:
an ‘alias’ to identify the device
ip address of the device
port of the device
number of sensors (2 by default)
By default the auto configuration feature is enabled (
<property name="enable-autoconfiguration" value="true"/>) so the plugin
is able to add a configured thing on the map.
The type of thing is based on the unit read from the sensor: Thermometer for ‘C’. ‘F’ or ‘K’; Barometer for ‘%’.
First of all you have to set this property
<property name="enable-autoconfiguration" value="false"/> to disable auto configuration.
Add a Thermometer thing to your Freedomotic environment and then:
Right click on the Thermometer in the environment to show its configuration panel
Change the property protocol to hwgste
Change the property address to a string composed of ALIAS:SENSOR-ID where ALIAS is the alias used to identify your device and SENSOR-ID is its id. An example address can be board1:215.
Under temperature (in Data Sources) select from the list
HWg-STE reads temperature.
The same procedure is required for humidity. In this case you have to add a Barometer thing to the map, set address and protocol as described previously
and assign the trigger
HWg-STE reads humidity to humidity behavior.
