# Monitor & Information Rest API for Raspberry PI

This is a very lean little project based on SpringBoot 2.0M7 and [Pi4J](http://pi4j.com).

# Pre-requisites

* [JDK 8](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html) - apt install oracle-java8-jdk
* [Maven 3x](https://maven.apache.org/download.cgi) - apt install maven

# Download
Make sure you are in /root directory first then....

```git clone https://github.com/sgrayban/raspberrypi.monitor.git```

# Build as root

Simply

```bash
cd /root/raspberrypi.monitor

mvn clean install
```

# Install raspberrypi_monitor.service as a Systemd script to start at boot

```bash
cp raspberrypi_monitor.service /etc/systemd/system/raspberrypi_monitor.service
systemctl daemon-reload
systemctl enable raspberrypi_monitor.service
systemctl start raspberrypi_monitor.service
```

Then to make sure the app is running

```bash
systemctl status raspberrypi_monitor.service
```

# Usage

```
http://Rpi-IP:8080/api/pi
```

Would yield something like this:
