Luxtronik2

Luxtronik2 reads and controls heat pumps based on the Luxtronik 2.0 contol unit with Node.js.

This work based on the fantastic FHEM module 'LUXTRONIK2', the very usefull openHAB binding 'Novelan Luxtronic heat pump', the extensively cbrandlehner/homebridge-luxtronik2 and a little bit research of my own. Hope you will like it.

Supports the following heat pumps

• Alpha Innotec
• Siemens Novelan (WPR NET)
• Roth (ThermoAura(r), ThermoTerra)
• Elco
• Buderus (Logamatic HMC20, HMC20 Z)
• Nibe (AP-AW10)
• Wolf Heiztechnik (BWL/BWS)
• CTA (Aeroheat AH CI 1-16iL)

Installation

npm install luxtronik2

How to use

Connect your unit via lan and configure the ip parameters at your unit. The port number of your unit is 8888 by default. Clone this code via git or simply via npm. You will get a package named luxtronik. You can require this at your code to read and write to your heat pump.

Examples

var luxtronik = require('luxtronik2');

const hostIp = '127.0.0.1';  // <- Enter your Luxtronik IP here
var pump = new luxtronik.createConnection(hostIp, 8888);

// read all readable data
pump.read(function (err, data) {
    if (err) {
        return console.log(err);
    }
    console.log(data);
    console.log(data.values.errors);
});

// set heating target temperature to 0 °C
pump.write('heating_target_temperature', 0);

// set warm water target temperature to 60 °C and use callback
pump.write('warmwater_target_temperature', 60, function (err, res) {
    if (err) {
        return console.log(err);
    }
    console.log(res);
});

// set heating operation mode to 'Auto'
pump.write('heating_operation_mode', 0);

// set warm water operation mode to 'Auto'
pump.write('warmwater_operation_mode', 0);

// set heating target temperature and use callback
pump.write('heating_target_temperature', 0, function (err, res) {
    if (err) {
        return console.log(err);
    }
    console.log(res);
});

Ability to plug in to processing data

It is possible to plug in to data processing by passing third option into createConnection function (or Luxtronik constructor). See the example below:

const pump = luxtronik.createConnection('192.168.0.190', 8889, {
    onProcessValues: function (heatpumpValues, heatpumpVisibility) {
        return {
            additional_value: (heatpumpVisibility[24] === 1) ? heatpumpValues[13] / 10 : 'no',
        };
    },
    onProcessParameters: function (heatpumpParameters, heatpumpVisibility) {
        return {
            additional_parameter: (heatpumpVisibility[207] === 1) ? heatpumpParameters[11] / 10 : 'no',
        };
    },
});

pump.read(function (err, data) {
    if (err) {
        return console.log(err);
    }
    console.log(data);
    console.log(data.values.errors);
});

Output:

{
  values: {
    additional_value: 'no',
    // ...regular values
  },
  parameters: {
    additional_parameter: 26.5,
    // ...regular parameters
  }
}
[
  // ...errors will go here
]

read/set runDearate

Note: you need to set "runDearate" directly after you set the related pump, otherwise the Lux will not start the pump!

Example code:

const value= 1;
pump.write('solarPumpDeaerate', value, function (err, data) {
    if (err) {
        return console.log(err);
    }
    console.log(data);
    console.log("done");

    pump.write('runDeaerate', value, function (err, data) {
        if (err) {
            return console.log(err);
        }
        console.log(data);
        console.log("done");
    });
});
