ORCA Heat Pump Communication

ORCA Heat Pump Communication is a communication helper which enables you to read and write tags from/to ORCA Heap Pump devices. It was specifically developed for DUO 300 model, but I presume it should also work with other models.

How It Works

orca-heat-pump-communication communicates with Heat Pump device via exposed cgi api. After initialization readTags and writeTags functions are exposed, which enables you to read and write tag values.

Install

npm i orca-heat-pump-communication --save

Usage

const Orca = require('orca-heat-pump-communication')

const settings = {
  host: '192.168.1.111',
  username: 'username',
  password: 'password'
}

const {
  readTags,
  writeTags
} = Orca(settings)

// read tag values
const tags = ['2_Temp_prostor_dnevna', '2_Temp_Zunanja']

readTags(tags)
  .then(res => console.log(res)) // [{ tag: '2_Temp_prostor_dnevna', status: 'S_OK', value: 22.5 }, ...]
  .catch(err => console.error(err))

// write tag values
const tagValues = [
  { name: '2_Temp_prostor_dnevna', value: 22.5 },
  { name: '2_Temp_Zunanja', value: 5.7 }
]

writeTags(tagValues)
  .then((res) => console.log(res)) // [{ tag: '2_Temp_prostor_dnevna', status: 'S_OK', value: 22.5 }, ...]
  .catch(err => console.error(err))
