Thank you very much. It works fine and much more stable than the heatpumpmonitor on the Fritzbox 7270, fortunately.

One small thing which is not working:
The Booster values are always Zero, even when the heatpump runs on first or second Booster (see attached screenshot)
I assume this may be due to manufacturer- model- and Firmwareversion differences.

@immi: My time is limited - and yours as well I am sure - but could you maybe though give me a hint/how you Analyse the traffic and find out the values etc?
... what I have up and running: FHEM on 7270 with usbserial/FTDI kernel Drivers. LWZ303Sol connected via USB/RS232 Adapter to the Fritzbox. Additionally Network Connection to that via ser2net and HWVirtualSerialPort on the Laptop. On it running the Stiebel Eltron Service Software for the LWZ.

Thanks for your time

Hi xyz_fhem
if you have  a Network Connection  via ser2net to HWVirtualSerialPort, run the Stiebel Eltron Service Software and log.
You can activate the logging function of ser2net: the command of ser2net "TB" is your friend.

you better be lucky that the booster is always 0. The booster is the electrical auxiliary heating which is only activated in the case the heatpump cannot reach the designated temperatures itself. This can maybe caused by very low temperatures like below -10°C.

auf deutsch:
der booster ist nur fuer den fall, dass die waermpepumpe die solltemperaturen alleine nicht schafft. das ist beispielsweise bei sehr niedrigen aussentemperaturen unter -10°C der fall. somit solltest du dich eigentlich freuen das der booster aus ist ;)

Hallo,

habe eine LWZ 404 und bisher noch keinen Erfolg mit der serialen Schnittstelle gehabt, läuft das Modul auch mit der x04 Serie, oder nur mit den 303/403?

Gruß
Micha

Hi,
keine Ahnung obs mit der 404er auch geht.
Versuch doch mal mit den seriellen Geschwindigkeiten zu spielen.
Oder den USB onboard zu nutzen (sollte der noch an der gleichen Stelle sein).
Bei USB sollte es mit 115200bau funktionieren.
Welche Software ist denn drauf?

Gruß,
Markus

Hi michaelk68
Markus is right: No Idea if the 404 is using the same comunication protocoll.
There is no documentation of the protocolls from Tecalor :(
Old protocolls have been described by reverse engeneering (logging of the serial comunication).

Let us start slowly
First we need to understand:
1) do you have a bad serial communication (hardware/cable/contacts defect) ?
2) Do you have a bad configuration of the serial port (wrong baudrate/wrong port) ?
3) does the protocoll of 404 differ from 403/303?


for 1 and 2 test your hardware with another serial appliance.
for 3 tell us which firmware do you have on the heatpump


best regards
immi

Hi immi and Markus,

I have a 404 with software release 5.39.
I tested with a laptop and a raspberry with a serial-USB adapter and different baudrates without success over a serial cable, with the pin layout from Robert Penz.
I think the cable is right.


Best regards
Michael

Hi Michael
you have to be sure that
1) do you have a bad serial communication (hardware/cable/contacts defect) ?
2) Do you have a bad configuration of the serial port (wrong baudrate/wrong port) ?

in order to be sure send hex "02" from a terminal emulator.
If you have 1 and 2 without errors, the heatpump answers Hex "10"

Hi,

5.39 sounds to me like a modified 4.39 to fit the new hardware in the 404.

You could try to connect via the internal USB interface on the controller board with 115200 baud.
On my 303 the serial interface did not work at all. Only with the onboard USB i got the connection running.

Could you provide a ZIP code from where you live?

regards,
Markus

Hi,

I'm located in 88699, will test it over the weekend with an USB cable.
Do you have an idea, with which program I can test the connection under windows?

Hallo Zusammen, ich habe eine 303 (Version noch nicht herausbekommen). Bekomme leider keine Daten geleifert. Muss ich den LOG bei der LWZ aktivieren? Brauche ich zwingend, die Service Software von Stiebel?

oh thats not so far :)
i'm in 86920.

just take an ordinary USB cable Type A to Type B like it's used for printers.
http://www.amazon.de/USB-2-0-Kabel-grau-3m/dp/B0013F8R8I
If the USB is the same as on 303 it fits perfectly.

I will look for the tool i used for testing and let you know the name today.

Best,
Markus

Okay, wie bist DU mit der 303 verbunden? Seriell oder USB?
Hast Du ein Terminalprogramm mit dem Du die grundlegende Kommunikation testen kannst?
Auf der 303 muss nichts weiter konfiguriert werden, das funktioniert out-of-the-box.
