# Eclipse VOLTTRON™

Eclipse VOLTTRON (eclipse-volttron/volttron-core) is an open source platform for distributed sensing and control. The platform provides services for collecting and storing data from buildings and devices and provides an environment for developing applications which interact with that data.

[![pypi version](https://img.shields.io/pypi/v/volttron.svg)](https://pypi.org/project/volttron/)

## Prerequisites

- poetry >= 1.8.2
- python >= 3.10
- pip >= 24.0

  Note: Ubuntu 22.04 comes with python 3.10. To upgrade pip run ```python -m pip install --upgrade pip```

## Installation

This package installs the main components of Eclipse VOLTTRON (volttron-core, volttron-lib-auth, volttron-lib-zmq).

It is highly recommended you use a virtual environment for installing volttron.

```shell
python -m venv <directory name for your virtual env. for example .venv>
source .venv/bin/activate
export VOLTTRON_HOME=</path/to/volttron/home>
pip install volttron
```

Note you can also run ```pip install volttron-core volttron-lib-zmq volttron-lib-auth```

### Quick Start

 1. **Setup VOLTTRON_HOME** environment variable: export VOLTTRON_HOME=/path/to/volttron_home/dir

    **NOTE** This is mandatory if you have/had in the past, a monolithic    VOLTTRON version that used the default VOLTTRON_HOME $HOME/.volttron. **This modular version of VOLTTRON cannot work with volttron_home used by monolithic version of VOLTTRON(version 8.3 or earlier)**

 1. **Start the platform:**

    ```bash
    volttron -vv -l volttron.log &>/dev/null &
    ```

 1. **Install agents and optional libraries**:

    Each volttron agent is in it own repository. Each agent's repository will have its own readme with instructions on how to install the agent and any optional libarires that could be used with the agent. But in general, agents should be installed using vctl install command. 
    
    For example, 
    ```bash
    vctl install volttron-listener
    ```

    All libraries that the agent depends on will automatically get installed in your current python environment.
    
    **Optional Libraries**

    In addition to mandatory libraries that are automatically installed during agent install, some agents could have optional features that are enabled or disabled based on availability of additional libraries. For example, an agent could support unit conversion if the python pint library is installed in the python environment. In order to install optional libraries use
    ```bash
    poetry add --directory $VOLTTRON_HOME <library name>
    ```
    
    Modular VOLTTRON uses poetry for dependency management. When VOLTTRON is started, it creates a poetry project (pyproject.toml file) in VOLTTRON_HOME directory and uses that for keeping track of all installed packages. For example, when you run ```vctl install volttron-listener``` an entry for that agent's package name and version gets added to $VOLTTRON_HOME/pyproject.toml.
    If you are installing optional libraries, such as pint use ```poetry add --directory $VOLTTORN_HOME pint``` instead of pip.  Poetry will check if the version of volttron-core (and other librabries) in your current activated environment is compatible with requirements of the version of volttron-lib-bacnet-driver you are installing.

    **Warning:** You could use pip to install librabries, but pip will not check dependent library versions for compatibility and simply overwrite packages in the current environment. For example, if you are running volttron-core version 2.0.0 and volttron-lib-bacnet-driver has dependency on volttron-core version 1.0.0, ```pip install volttron-lib-bacnet-driver``` would overwrite volttron-core version 2.0.0 with version 1.0.0. However ```poetry add --directory $VOLTTRON_HOME volttron-lib-bacnet-driver``` will fail because of a version incompatibility error.
    


 1. **View status of platform**

    ```bash
    vctl status
    ```

 1. **Shutdown the platform**

    ```bash
    vctl shutdown --platform
    ```
