energy-storagejs

energy-storagejs is a JavaScript library for accessing and retrieving data from energy storage systems. It provides an API for interacting with VARTA Storage Systems and retrieving battery-related information.

Installation

You can install energy-storagejs via npm:

npm install @robinrs/energy-storagejs

Usage

// Access API Class Object
const battery = energyStorage({
  ip: '192.168.2.130',
  fullRequest: '/cgi/ems_data.js',
  simpleRequest: '/cgi/ems_data.xml',
  paramsRequest: '/cgi/ems_conf.js',
  type: 'v', // Type for VARTA Storage Systems
});

// Request the data from the Battery
await battery.requestSimple();

// Data can now be accessed in raw format, to use the provided methods, parse the data
battery.parse();

Once parsed, the following methods can be used to retrieve battery information:

• getTimeStamp(): Returns the timestamp of the data.
• getState(): Returns the state of the battery.
• getPercentageF(): Returns the battery percentage as a formatted value with the unit.
• getPercentage(): Returns the battery percentage.
• ... Check out the docs to see all methods

TODO

Please note that this package is still a work in progress. The following tasks are currently being worked on:

• [] Add comments to further explain the code.
• [] Implement the handler for more detailed requests.
• [] Implement an interval to keep the data fresh.
• [] Add support for more battery systems and companies.
