Easy-rscp NPM | npm.io

easy-rscp-js

easy-rscp is an INOFFICIAL library written in Typescript (fully JS compatible) for accessing E3DC home power stations.

E3DC is a brand of HagerEnergy Gmbh (website). I have nothing to do with the company, except that I own a home power plant from E3DC and wanted to include it in my SmartHome. This "desire" gave birth to easy-rscp.

This library is a port of easy-rscp. Most of the classes and principles from easy-rscp also work here.

Getting started

The library was developed from the kotlin library easy-rscp. The documentation of the kotlin library is very detailed and has been supplemented by the typescript information. You will definitely find what you are looking for there. easy-rscp-docu

You can use the library in 2 different ways, either you use the ready-made services or, if you need more functions, you can use the low-level API.

installation

npm i easy-rscp

Service

import {
  DefaultHomePowerPlantConnection,
  DefaultInfoService,
  E3dcConnectionData,
  RijndaelJsAESCipherFactory
} from 'easy-rscp-js';

const connectionData: E3dcConnectionData = {
    address : 'IP of your home power station',
    port : 5033,
    portalUser : 'user username for the e3dc portal',
    portalPassword : 'the corresponding password',
    rscpPassword : 'The RSCP password that is configured on the home power station'
}

const aesFactory = new RijndaelJsAESCipherFactory(connectionData.rscpPassword)
const connection = new DefaultHomePowerPlantConnection(easyRscpConnectionData, aesFactory)
const infoService = new DefaultInfoService(connection)
infoService
    .readSystemInfo()
    .then(infos => {
        console.log(infos)
    })
    .catch(e => {
        console.error(e)
    })
    .finally(() => connection.disconnect())
