I’m after some system like Google Cloud Messaging, to send notifications to a local application, a supervisory made in java, running locally (it in turn connected to a microcontroller).
The idea was that this supervisory did not need to keep sending requests to the Web Service, to see if there is any action for it to perform. For mobile applications there is GCM, but for this my local application I could not find anything that does the work like GCM.
If it does not exist I will have to stipulate a time and cyclically send request to Google Cloud by local application and request the actions I have, but this way there will be too many requests, because I won’t have actions run every time the app asks for Google Cloud.
