Monitor & Information Rest API for Raspberry PI

This is a very lean little project based on SpringBoot 2.0M7 and Pi4J. I'm planning to use this in a SmartThings SmartApp later so I can see my Pi's status in the SmartThings app. The idea came from here

Pre-requisites

• JDK 8
• Maven 3x

Build

Simply

mvn clean install

Install on Pi to Start at Boot Up

Change the src/main/resource/application.properties file and set the IP address or hostname of the Pi for the variable upnp.config.address. You can also pass this information with the -Dupnp.config.address=<myipaddress> parameter at startup

sudo nano /etc/rc.local

Then add the below line above the last one (that exits)

java -jar /path/to/jar/raspberrypi.monitor.jar &

Usage

http://raspberrypi:8080/api/pi

Would yield something like this:
