Node-RED contribution package for Luxtronik2 heat pump controllers

Attention: unfortunately I dicovered just after I buzilt and published this repo that there is already a node called node-red-contrib-luxtronik2. You can find it here: coolchip/node-red-contrib-luxtronik2

Anyway, as far as I can tell my node works fine and I'll stickto it.

Install

TBD

How to use

1. Place the node within your flow
2. Configure the IP of your Luxtronik and the port (8888 for SW versions < 1.76, 8889 for SW versions >= 1.76)
3. Trigger the node via the input, it doesn't matter what type the input is
4. The node querys the heat pump for the data, parses the response and outputs the parsed result

Data format

The result is an object of objects:

{
    10: {
        id: "ID_WEB_Temperatur_TVL"
        description: "Vorlauftemperatur Heizkreis"
        value: 42.3
        type: "celcius"
        }
    11: {
        ...
        }
    ...
}

• The key is the index as received from the heatpump
• id is the identifier as used by AIT within their java code
• description is mostly the description text out of the java code
• value is the parsed and converted value
• type describes what kind of data the datapoint is

Authors

The module was developed by Bouni inspired by a post seen on the loxforum. The detailed information comes mostly from reverse engeneering the java applet sent by the heat pump when one loads the web interface.
