Notify My Android from OpenRemote

Openremote android app is not very useful for detecting alarm situations from OpenRemote. It lacks push notifications, however it is quite simple to use a 3rd party push solution like Notify My Android.

Here is example of NMA app screen on my smartphone with messages from OpenRemote:
NMA OpenRemote

The steps to do this are:

  • Create an account by Notify My Android and generate ApiKey which you will need for sending notifications. Put it in the following code in place of [your ApiKey from notifymyandroid.com].
  • Install NMA app on your Android device(s).
  • NMA offers many APIs but for OpenRemote the most obvious one is Java api. Download NMAClientLib.jar and place it in OpenRemote-Controller/webapps/controller/WEB-INF/lib/ directory.
  • Add the following rules:
// Notify my Android NMA
import com.usk.lib.NMAClientLib;

declare NMA_message
  apiKey : String
  appName : String
  priority : int
  event : String
  desc : String
  devKey : String
end

declare My_NMA
  message : String
  priority : int
end

rule "System start"
when eval(true)
then
  My_NMA nma = new My_NMA("OpenRemote controller's drools started", 1);
  insert(nma);
end

rule "System NMA"
when
  $vt : My_NMA()
then
  NMA_message n = new NMA_message();
  n.setApiKey("[your ApiKey from notifymyandroid.com]");
  n.setEvent("System");
  n.setDesc($vt.getMessage());
  n.setPriority($vt.getPriority());
  n.setDevKey(null);
  insert(n);
  retract($vt);
end

rule "Notify my Android"
when
  $n : NMA_message()
then
  try{
    if(NMAClientLib.notify("OpenRemote", $n.getEvent(), $n.getDesc(), $n.getPriority(),  $n.getApiKey(), $n.getDevKey())!=1)   
      throw new RuntimeException();
  }finally{
    retract($n);
  }
end
// NMA

This code will generate “OpenRemote controller’s drools started” notification with priority 1 each time the controller boots. Notifications are very handy for debugging rules file.
