wallbox

Overview

This API wrapper was written to allow me to get better metrics and usage out of my wallbox EVSE.

Usage

To start, simply download the package using composer:

composer require dutchie027/wallbox

After downloading it with composer, open wallbox.ini and enter your variables and credentials.

Once you have all of that, depending on how you want to use it, create a simple PHP file that calls the library:

#!/usr/bin/php
<?php

include_once 'vendor/autoload.php';

$wallbox = new dutchie027\Wallbox\Wallbox();
...

Running as a monitor

The most common use case for the script(s) are a monitoring system. To accomplish this, there is a function called monitor that uses a lot of defaults and will notify you of changes to the system. It will check the EVSE every 30 seconds by default and notify you of any changes using pushover with the configuration settings in .env. To monitor the system, first create a file called monitor.php using the below:

#!/usr/bin/php
<?php

include_once 'vendor/autoload.php';

$wallbox = new dutchie027\Wallbox\Wallbox();
$wallbox->monitor();

After you've created the monitoring file, ensure it's executable by running chmod +x monitor.php. Once you've done that, simply trigger it with a nohup so it runs in the background:

nohup ./monitor.php >/dev/null 2>&1 &
