Hi everyone !

I just wanted to share the results of my (really) nerdy Sunday. I was able
to send a Push Notification to my Lego EV3 Robot using the UnifiedPush
Server. The robot throws a ball when it receives the notification :)

The robot is under Linux and can run  the JVM. I've been using our Java
SimplePush client (
https://github.com/aerogear/aerogear-simplepush-java-client) hacked with
 Matzew's  WebSocket Java Client (

The UPS instance is from the OpenShift Cartridge and the Simple Push
Server, is the vert.x version, also running on OpenShift.

In this small video I show the Robot and my Android Device both receiving
the notification : https://www.youtube.com/watch?v=4uqfcqq42es

This is an interesting use of the SimplePush Protocol since every connected
device/object is eligible for the UPS ;)
