GrowControl is a computer automation system for your home and garden, or hobby projects. It's expandable with plugins, fully multi-threaded makes it fast, and your ideas make it powerful. The basic system comes in 4 parts, all of which are optional and can be customized. * The server is the core of the system, coordinating all the events and actions. Normally, this will run silently in the background on some small device. The client can be run in stand-alone mode, which makes the server optional. * The client is an application which you can run on your desktop or laptop. The client is the graphical interface to communicate with the server. This program can show you the state of your entire system, or make changes. The server can continue running as normal without the client being in use, unless of course you're running in stand-alone mode. * The plugins are what give the system its functional power. Without plugins, the client and server do very little. Officially supported plugins, as well as 3rd party contributed plugins are available on growcontrol.com * The hardware is the last piece you'll need to make it all work. It too is optional, as there are many plugins which can be used without extra hardware. The Arduino and its variations are commonly used, and can easily read sensors, control 120v outlets using relays, or any number of other devices. Requirements ------------ To use the GrowControl server/client software, you'll first need to install the latest Java Runtime. On linux, either the OpenJDK or the official JRE/JDK will work. Most libraries which are needed are already included in the jar package. The GrowControl Server has minimal system requirements, and will run happily on almost any system, new or old. In order to flash the Arduino devices with the sketches provided by GrowControl, you'll need the Arduino IDE which can be found here http://www.arduino.cc/ Most sketches will run on the ATMega328 based Arduino's, such as the Arduino Uno. Sketches which require more resources are noted at the top of the sketch file, and will run on any SAM3X8E based Arduino, such as the Arduino Due, or the Udoo. Installing ---------- Installing on a Redhat derived distro such as Fedora or CentOS is simple. RPM's can be found on the http://growcontrol.com/ website, or you may receive automatic updates using the yum repo which can be installed using http://yum.poixson.com/latest.rpm . This yum repo may be discontinued once the project is submitted to a mainstream repo, in which case only the testing repo will be provided at this location. Download Links: http://dl.poixson.com/ - All build versions can be found here, in both rpm and jar formats. http://yum.poixson.com/ - Only the most recent rpm builds are provided here. Development ----------- Compiling GrowControl from source is relatively easy. There are a few tools you'll need, namely git and maven. Fedora/Redhat: sudo yum install git maven java-1.8.0-openjdk-devel Ubuntu: sudo apt-get update sudo apt-get install git maven openjdk-7-jdk From the locaton you'd like to set up your workspace, the following commands will download the workspace setup script, clone the github repositories, and build with maven. Most distros: wget http://dl.growcontrol.com/getgc.sh && sh getgc.sh Once this completes successfully, you'll have eclipse projects ready to import, as well as a compiled copy of the project in GrowControl/target/ You may now open your workspace in Eclipse, then import the following project locations: pxnCommon/ GrowControl/common/ GrowControl/server/ GrowControl/client/ Manual Setup ------------ If you'd like to manually set up your workspace, this too is easy with a few commands. From the locaton you'd like to set up your workspace: git clone firstname.lastname@example.org:GrowControl/pxnCommon.git git clone email@example.com:GrowControl/GrowControl.git From within each of the directories, pxnCommon/ and GrowControl/ run the following: cd pxnCommon/ mvn clean eclipse:eclipse dependency:sources install cd .. cd GrowControl/ mvn clean eclipse:eclipse dependency:sources install cd .. You'll then find the compiled jar's in the following locations: GrowControl/target/ GrowControl/server/target/ GrowControl/client/target/ To compile again, you may run the following command anywhere you see a pom.xml file: mvn clean install Note: the files beginning with scant- contain only project specific classes. Required libraries aren't included in these jar's.
