Introduction

This is a Javascript module with Typescript support for communicating with a Blauberg Vento (as OEMS like Duka One S6w). The Blauberg Vento is a one room ventilationsystem with a heat exchanger.

This module has roots in the dukaonesdk but has been rewritten from scratch in order to better seperate reponsibilites into different classes, while still beig able to reuse shared logic.

The primary goal for this module is to create a Javascript client that makes communicating with Blauberg Vento(and its derivatives) a simple task. My personal need is to integrate it into Homebridge and node-red.

Installation

npm i blaubergventojs

The modules 2 levels of communication:

1. A low level client that mimics the communication protocol specified by Blauberg.
2. A high level resource that wraps the low level client for easier usage.

Low level Example

import { BlaubergVentoClient, FunctionType, Parameter, DataEntry } from 'blaugbergventojs'

const client = new BlaubergVentoClient();

// Find all devices on the local network
const addresses = await client.findDevices();

// Assemble package for reading ON_OFF state
const packet = new Packet(addresses[0].id, '1111', FunctionType.READ, [DataEntry.of(Parameter.ON_OFF)])

// Send package and wait for response.
const response = await client.send(packet, addresses[0].ip);

// Check value
const isOn = response.packet.dataEntries[0].value === 1;

High Level Example

import { BlaubergVentoResource, FunctionType, Parameter, DataEntry } from 'blaugbergventojs'

const resource = new BlaubergVentoResource();

// Find all devices on the local network
const devices = await resource.findAll();

// Change a device and save it
let device = devices.contents[0];
device.speed = 1;
device = await resource.save(device);
