How it works

With this plugin Freedomotic can communicate with an ethernet relay board by gce-electronics.  For more details visit the official site.

How to install this plugin

Please follow the instruction for sensors and actuators on the user tutorial

How to configure this plugin

The ipx800-manifest.xml file contains all the plugin configuration parameters. It's possible to control more than one board setting its parameters into a specific <tuple></tuple> block.

Here an example of configuration file:

        <property name="description"    value="Communicates with ipx800 board"/>
        <property name=""  value="ipx800"/>
        <property name="category"       value="protocol"/>
        <property name="short-name"     value="ipx800"/>
        <property name="address-delimiter" value=":"/>
        <property name="startup-time"   value="on load"/>
        <property name="change-state-relay-url" value="leds.cgi?led="/>
        <property name="send-pulse-relay-url" value="rlyfs.cgi?rlyf="/>
        <property name="get-status-url" value="status.xml"/>
            <property name="alias" value="default"/>
            <property name="ip-to-query" value="ip-board"/>
            <property name="port-to-query" value="port-board"/>
            <property name="relay-number" value="8"/>
            <property name="analog-input-number" value="2"/>
            <property name="digital-input-number" value="4"/>
            <property name="starting-relay" value="0"/>
            <property name="led-tag" value="led"/>
            <property name="analog-input-tag" value="analog"/>
            <property name="digital-input-tag" value="btn"/>

How to control an object with this board

With this board you can control the powered behavior of any electric device in your environment, meaning you can turn on/off electric devices.

For this example we use a light object:

  1. Open the file ipx800.xml into freedomotic/plugins/devices/ipx800 folder and set ip-address and port number of your  board
  2. Right click on the light object in the environment to show its configuration panel
  3. Change the property "protocol" to "ipx800"
  4. Change the property "address" to a string composed of ALIAS:RELAY_NUMBER:led  where ALIAS is the string used to identify the board, RELAY_NUMBER is the relay on which your object is connected (from 1 to 8 the maximum number of supported  relays) and led is used to retrieve the relay state from status.xml file.  An example address can be "default:1:led" this identifies the first relay on a board listening on port 80 of the http URL
  5. Under "turn on" (in Actions) select the command called "Turn on Relay on Ipx800 board"
  6. Under "turn off" (in Actions) select the command called "Turn off Relay on Ipx800 board"

 The plugin is able to read any relay status change and update the object one.

  1. Under "powered" (in Data Sources) select the command called "IPX800 board reads a state change"
