connection to THZ 303 partialy working

Asked by Heiner Pahlings

Hi,

I assume english is reaching a bigger community, but in case someone need a german translation, no problem, happy to write this again in German.
#####Deutsch: Ich gehe davon aus das diese Nachricht in Englisch mehr Leute erreicht, falls aber ein Helfer den Text besser in Deutsch versteht, die deutsche Version ist auch da.####

I have a THZ303 in Version 4.39. I connected via USB Adapter (Digitus) my Windows-Laptop and try to find out the rigth settings. Once I have choosen a speed of 57600 I got a resonse. So if I send 02 I recive back a 10 which is good. However no other command works !!! So I tried to send 01 00 FE FD 10 03 but no response until i Enter 02 and then I recieve again 10
I tried as well 01 00 FC FB 10 03 but equally no Response.
So I am puzzled, Do you have any idea?

##### Ich habe eine THZ303 in V4.39. Diese ist verbunden mit USB Adapter (Digitus) an ein Windows Laptop und ich versuche die richtigen Einstellungen zu finden.
Mit der Geschwindigkeitsstufe 57600 Baud erhalte ich das ersehnte Feedback. Auf mein gesendetes Komando "02" erhalte ich die Antwort "10". Leider funktioniert aber kein anderes Komando !!!! Ich habe sowohl "01 00 FE FD 10 03 " als auch "01 00 FC FB 10 03 " ausprobiert become aber keine Antwort.
Hat jemand eine Idee was da das Problem sein koennte?#####

By the way, I tested based on a Windows Laptp with a free test version of the Terminal SW "Advanced serial Port Terminal"
I tried Termite as well but there even my 02 command shows no response and I have no clue why.
With other windows terminal SW I have the trouble not to know how exactly to configure them, any suggested SW including it's configuration could help to validate my results as per above.

####Ich nutze ein Laptop mit Windows 7 und der shareware "Advanced serial Port Terminal". Mit einer Alternativsoftware wie termite become ich ueberhaupt kein Feedback der THZ, vermutlich habe ich aber nicht die richtige Einstellung bei termite gefunden ( fuer HEX IN/OUTPUT). Wenn jemand eine andere SW kennt die geht, kann ich gerne damit wieter testen um das Problem einzugrenzen,

As a next level I would like to test based on Ubuntu. Here comes by next challenge, the THZ is connected to another Linux device (my Fritzbox), can I somehow forward this port to my Ubuntu mashine to test from there?

#####Am Ende des Tages moechte ich die THZ mit der Fritzbox 7390 koppeln auf der Linux laueft aber noch nicht Python. Eventuell kann man ja einfach von einem Linux Rechner ( Ubuntu) auf den Seriellen Port der Fritz zugreifen um weitere Tests zu machen , leider Weiss ich aber nciht genau wie.######

Many questions but I hope ou can help.

####Bitte bitte helft mir####

Many Thanks upfront.

Dec 2013: Immi translated this SW for fhem and was able to help. the problem is that the code runs to quickly into the THZ, so by slowing down the code y some interim activities like "ls" the code is going to work.

Hello, I face the same problem when connecting to my LWZ 303 Sol. My setup is a Raspberry Pi with RS232 Interface. I used CuteCom as RS232 GUI. When entering hex 0x02, I receive 0x10. No response to the other requests as metioned above.
I found out that a request of "02 10 03" leads to a response "10 02". But then I also get stuck.
I tried the protocol approx two years ago from a PC and got the right responses back. But meanwhile my display has been replaced by a service guy and I don't know whether the software was also updated in my LWZ.
I don't think that just the new display is a valid root cause as the LWZ is also running without the display, right?

So any help on this topic is highly appreciated.
Thanks in advance.

Hi again,

I finally got it working after editing Robert's code with some debug print and wait statements.
It seems to be a GUI issue with the RS232 console GUI. The heatpumpmonitor is communicating correctly with my LWZ V4.18.

So this is solved for me.
I am still struggling with the rrdtool, but that's another topic....

Regards, Michael.
