The default parameter used in the function declaration luxtronik is not valid ECMAScript prior to version ES6. As coffee-script currently only supports ES5 your library cannot be used as part of coffee-script projects. It would nice if this could be changed by removing the default parameter value from the declaration and adding some code instead like the following:

if (typeof this._port === 'undefined')  {
        this._port = 8888;
}

Hi,

thanks for your module. I tried it on my AIT WZS82K3M (software version 3.84.3 on port 8889), but the module threw an exception:

RangeError [ERR_OUT_OF_RANGE]: The value of "offset" is out of range. It must be >= 0 and <= 0. Received 4
    at boundsError (internal/buffer.js:81:9)
    at Buffer.readInt32BE (internal/buffer.js:477:5)
    at Luxtronik.<anonymous> (/Users/tm/Documents/Dev/luxtronik/node_modules/luxtronik2/luxtronik.js:406:37)

This is caused by the "data" event function only receiving 4 bytes at first, but it expects and tries to evaluate the complete response.

I implemented a crude workaround. It fills a "dataBuffer" with the received data (in 2 events) and only processes the data when more than 4 bytes were received. This makes the module work with my heatpump.

The same applies to writing data (first data event receives 4 bytes, second event then receives the final 4 bytes), but strangely this only works for me when not reading all data before.

Luxtronik.prototype._nextJob = function () {
    if (this.receivy.jobs.length > 0) {
        this.receivy.activeCommand = 0;
// NEXT LINE ADDED:
        this.dataBuffer = undefined;
        sendData(this.client, [this.receivy.jobs.shift(), 0]);

        if(this.dataBuffer === undefined) {
            this.dataBuffer = data;
        }
        else {
            this.dataBuffer = Buffer.concat([this.dataBuffer, data]);
        }
        if(data.length > 4) {
            data = this.dataBuffer;
            if (this.receivy.activeCommand === 0) {
                const commandEcho = data.readInt32BE(0);
                ...
        }
    }.bind(this));

    this.client.on('close', function () {});
};

The write parameter "warmwater_target_temperature" does not update (german) "Wunschtemperatur" but "Deckung WP".
"Deckung WP" is not even settable on the heappump display itself.

Or do I have some misunderstanding?

I yesterday upgraded to Node 16 b/c of an other plugin, and instantly, the luxtronix plugin threw the following errors in the logs, leading node red to restart:

11 Apr 07:53:44 - [red] Uncaught Exception:

Would be great if AO2 (voltage HUP) could be adjusted (heatingSystemCircPumpVoltage )

Hello,

in the issue: [ "Mischkreis1" (MK1) missing #26 ] you implemented the MK1 values. -> Thank you for that!

Is it possible to write the MK1 values?
Especially these values are very interesting for me to better pre-heat my MK1 - Fußbodenheizung during the day with Photovoltaik-Power:
mk1_curve_end_point: 26
mk1_curve_parallel_offset: 26
deltaMk1Reduction: 0

And this value for the heating would also help much:
deltaHeatingReduction: 0

Can you please implement this?

Thank you very much!

Best Regards and greetings from Germany ;-)

Hi @coolchip,

I just checked your code because I want to create a PR with some additional parameters (de-aerate) - I currently have the issue, that at least one of my pumps get stuck every summer and needs to run regularly.
To my question: I found this mysterious byte-block 3005, what’s called “visibility”. It’s used for reading some values, like the “heating_curve_end_point”, which is checking the value “207”. The only “documentation” about this values I found here https://github.com/Bouni/Luxtronik-2/blob/master/documentation.md
But looking at 207, the related identifier of this is “ID_Visi_Sprachen_DANSK“ what doesn’t make any sense.
Can you elaborate, for what this visibility is used and what “207” stays for?
Happy to provide you a PR with some additional stuff.

The de-aerate props I have already in, just wondering, If I have anything to do with the visibility.

using the current master branch, with an Alpha-Innotec installation running version 1.76
If I run the read-only part of your test example.js I get the output below:

• Notice the values are all NaN, default or undefined.
• Firmware is also not visible
• But the Parameters are correct.

If I use a python component (https://github.com/Bouni/Luxtronik-2) I do get the values returned correctly. (i have included that output at the bottom).

For my ioBroker Adapter which is based on your library, I got the following request:
UncleSamSwiss/ioBroker.luxtronik2#123

Ich habe die Heizkurve für den MK1 nicht gefunden. Die Heizkurve für den Heizkreis ist vorhanden und kann man auch erfolgreich setzen (heating_curve_end_point und heating_curve_parallel_offset).

Nach Recherche müssten es diese Parameter sein:
14 - ID_Einst_HzMK1E_akt <-- Endpunkt Heizkurve MK1
15 - ID_Einst_HzMK1ANH_akt <-- Anhebung Heizkurve MK1
16 - ID_Einst_HzMK1ABS_akt <-- Nachtabsenkung Heizkurve MK1

Would you please be so kind to add these three variables?

Unfortunately I still have cases where we try to read more data than is available. In this case, the problem seems to be that we received 4 bytes of data but already want to read the first 8 bytes:

RangeError [ERR_OUT_OF_RANGE]: The value of "offset" is out of range. It must be >= 0 and <= 4. Received 8

When I set the value of warmwater_target_temperature (write id=2), my heat pump display doesn't update the hot water target temperature.

When I change the hot water target temperature on the heat pump, it is not only warmwater_temperature (id=2) that changes, but also temperature_hot_water_target (id=105). My guess would be, one should set temperature_hot_water_target instead of warmwater_target_temperature.

How to use "Support RAW write operations #20"
How can i change the timer tables for circpump?

Example has no effect
const circPumpTimerTable = [ {on: "07:30", off: "11:00"}, {on: "14:00", off: "22:00"} ];
pump.write("hotWaterCircPumpTimerTableWeek", circPumpTimerTable);

Kann geschlossen werden.

Hello,

I just reworked my heatpump monitoring system back from websocket API to this library.

After identifying almost all parameters I am just left with the following parameter available in the websocket / web UI but not in this library: "Laufzeit Ø VD1". I also did not find any related RAW parameter in the docu.

Does anybody know which is the related parameter provided by this library or alt. the underlying RAW parameter?

Thanks!
Sebastian

Hi guys,

I recently discovered that my Webserver UI also displays the consumed energy in kWh ("Eingesetzte Energie"). I'm posting the xml response I get after login below.

I was not able to find anything resembling the values when dumping all calculations and parameters (also tried the bouni python version). Was anyone able to find it and could we add it here? Are they maybe encoded in any other way?

It also would be great to have the current power consumption, if anyone can find it. I know I could also take the time derivative of the energy in kWh, but that is quite slow/delayed. Instantaneous power would be amazing!

Thanks for any help, love what you've done so far!

My AIT heat pump is equipped with passive cooling. In the Luxtronik setup menu there is a parameter Lstg. Kühlung (German) which ist the equivalent of heating_system_circ_pump_voltage_nominal but is used only when the heat pump is in cooling mode. It defines the power of the internal HUP when the heat pump is in cooling mode.

Would be nice, if you could add this to your library.

If you need more info, please tell me what you need.

Hi,
First thank's for your work, really appreciate it and use your module on my apps. Just one think is currently terrible for me, German language for whole messages.

Looking at your code I see that you created the file type.js to manage these messages and wrote all of these in German.

Just thinking if we can replace this file by the node module i18n, create the json file for German which while be the default one, then we could start any other translations from their (I need Fr or En).

What do you think? I could help to implement this if needed from your side.

Regards

Cedric

I have installed the luxtronic2 adapter. All data are visible (great job), but I get 2 warning messages:

1. Unknown data item parameters.solarPumpDeaerate

Does anybody have an idea how to fix it?

heatingCurveEndPoint should also be made configurable (get | set)

'heating_return_temperature':{
 setParameter: 11, 
 setValue: utils.value2LuxtronikSetValue(utils.limitRange(realValue, 20, 55)) 
 }

heatingCurveOffset should also be made configurable (get | set)

I've been using this integration happily for quite some time now. However, I often (one to a few times per day) find log errors referring to this component, and I don't know what this means. The integration seems to work fine otherwise. I want to know if this is something that I can fix. The error is below:

Again, the integration seems to work fine for the most part. If there are hiccups or glitches, I am unaware of them. I'm just trying to find out if I can fix this error reporting.

So far I did not further analyze the affected code. But these 10 reboots just happened without any modification in NodeRED.
Maybe the heatpump had a problem or any of the involved network hardward.
But suddenly the system somehow recovered and NodeRED was working again without any exceptions.

Hey,
is it possible to read the freq from VD1?

Hi
When I'm using 0.1.1 in https://github.com/bakito/pimatic-luxtronik2 I get the following error.

Block-scoped declarations (let, const, function, class) not yet supported outside strict mode

see: https://travis-ci.org/bakito/pimatic-luxtronik2/builds/221786054

I'm not quite sure what causes the problem, since my JavaScript Know-How is limitted.

Pimatic runns only on node 4.

Do you have any idea?
