HWg-STE Ethernet thermometer

Description: This plugin reads values from an ethernet thermometer by HW-group.com

Type: Driver - Categories: HVAC

Development status: Stable Release

Tested on: All platforms

Developer: Mauro Cicolella

Overview

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).

Configuration

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)

How to read data from a sensor

Automatic setting

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 ‘%’.

Manual setting

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.
