THZ Tecalor (LWZ Stiebel Eltron) module support and code improvement.

[immi]

you can find the register via reverse enginnering (man in the middle) if you have a service software or by trial and error
in this case, there is also a easy debug feature in the module at line 1821
you can  call it via

Code Auswählen Erweitern

get Mythz debug_read_raw_register_slow
It locks fhem for some minutes and at the end writes the results in logfile and in the filesystem "data.txt".
It makes very sense that you share all your register-outputs, uploading in the forum data.txt


considering github; do not make pull-request there; publish your code changes in the forum here and I decide how to merge them

line 1897
i tell fhem which %sets and %gets to use for 2.14
just add a simical case for 2.16

What is the difference between sets and setsonly, and for getsonly2xx and getsonly214, respectively?

Code Auswählen Erweitern

        elsif ($attrVal eq "2.14") {
            %sets = (%sets206, %setsonly214);
            %gets = (%getsonly2xx, %getsonly214, %sets206);
            THZ_Refresh_all_gets($hash);
        }

Now I have just copied that elsif clause with the same variables (of course with $attrVal eq "2.16" instead, but the rest the same). Does that (currently) make sense?

line 829
here I define %getsonly214 as a list of registers 01,02,F2,F4,FB and how we decode the answer from the heatpump (respectively 01pxx214, 02pxx206 ....)

Similarly, here I have copied the block for %getsonly214 but renamed to to %getsonly216 as a start.

line 73
here is defined how to decode the answer from the heatpump for 01pxx214

Finally, here I again copied the block 01pxx216 and renamed it to 01pxx214 (and kept the other stuff unchanged.

Now I would go checking what happens.

If you think I already made a mistake, please kindly let me know. Thanks a lot!


Since I am (again) new to FHEM, I still have to find out how to load the updated 00_THZ.pm for testing.

[immi]

What is the difference between sets and setsonly, and for getsonly2xx and getsonly214, respectively?

getsonly2xx is a common denominator of registers which are equals for all 2.xx; specialities of 2.14 shoul be in getsonly214

when you give me your specialities of 2.16, we can think how to organize them.

Ok, sounds good. I am still searching the wiki and other sources to understand how I either replace the official 00_THZ.pm in my FHEM installation, or how to load it after renaming it to e.g. 00_THZ_test.pm. If you happen to have a quick hint for me where to look for that, I would be very grateful. Maybe I am looking in the wrong places. 

PS:
"Specialties" in my case would be anything different or in addition to the INTEGRAL firmware 2.06, I assume, since it has the same age as my SOL 2.16 firmware. Maybe it makes to first ignore "specialties" and confirm the other (identical) parameters?

just overright it and restart fhem;
you can always get the original from github or just by updating fhem

[sunrise]

I feel ashamed to ask: How can I overwrite 00_THZ.pm?

[willybauss]

look on your fhem server in /opt/fhem/FHEM. The used version is located there. Move it to a different directory or rename it, in order to have a backup. Then copy the modified file to /opt/fhem/FHEM.

That's my understanding of what you should do.

Great, so easy - thank you!

I have marked below in red font what I find "not normal" (at least I suspect there a problem with the readings due to different firmware).

insideTemp is 0, because I have no inside temperature measurement

The "x08: FF4D" looks strange here, as well as the "normal roomSetTemp: 1459.2" and following 3 parameters ("x64", "x72", and "x76"), at least I wonder about these parameters' names. Do they mean parameters P64, P72, and P76?

I have no HC2, but nevertheless these values are shown. Is that ok? (I mean THZ module testing-wise)

The "heatingHours" in reality is much larger (>10 years of use), but maybe that is because of technical repair with electricity switched off a while ago by an SE technician.

The other values look ok - at least in so far I could check them on the LCD display. Some of them change within seconds, e.g. fan speeds, so I just checked them for plausibility.

Sorry, I forgot the log - see now below. There, too, are some values that do not look right. Specifically, almost everything that is HC1-related and HC2-related, seems awkward.

The value "4E0C08FC02BC7F00" appears for all HC2-related parameters. Remember that I have no HC2 (at least not to my knowledge), but only one "Heizkreis". Maybe that is the reason for these strange values? What should the behaviour be for parameters that are not applicable? Should the values be "n.a." or null/0/zero, or something else?

The value "700B08FC02BC1F00000003206000" appears for all HC1-related parameters, but I understand that I must have at least HC1 (one "Heizkreis"), right? Then why do all HC1-related values appear like this?

My suspection: If there is only one "Heizkreis" (heating circuit, HC), then the above shown parameters for HC1 and HC2 are not applicable and show values that do not make sense. Can somebody please confirm this or let me know how this is to be understood? Thank you so much!

PS:
Some HC1- and HC2-related values are ok, though, e.g. P13 through P20.

[willybauss]

I added a complete set of readings from my firmware version 4.19. You'll see that at least a part of your mentioned issues exist here as well, e.g. the strange x36 reading. Reason is that during the reengineering work phase nobody had an idea what kind of property x36 may be, and even nobody missed a useful parameter what could be mapped to x36. Therefore nobody made efforts to interpret the reading in any way. So, if you really miss an important property you may try to find it inside the given readings or alternatively find out additional readings ... But it may be useless effort to try interpreting readings what hadn't been mapped to useful properties since years.

Hi  Willy
it is some time we have not done any reverse eng...... remember the good old days moving in the dark

Hi Sunrise
happy you start to have fun. Maybe also andre.k can give you a hint. He decoded most of 2.x untill now.

 Thank you so much! I will further look into this. However, i see no point in trying to find out about parameters that have been and still are unknown for such a long time, especially when I can find workarounds (primarily, I am interested and a more effective cooling and found the recent hints very promising, but the thread here is for the code, so I will stick to the topic ).

BTW, I had used the heatpump monitor from Robert Penz and remember - vaguely, though - also the reengineering. That was indeed very tough.

Hi sunrise

the parameter names like x08 are not reengineered. The names are placeholders. The number 08 is the position in the answer string returned from THZ

get sHC1:
Zitat

    outsideTemp: 21.2 x08: FF4D returnTemp: 30.2 integralHeat: 0 flowTemp: 31.7 heatSetTemp: 23.7 heatTemp: 30.6 seasonMode: summer integralSwitch: 100 hcOpMode: normal roomSetTemp: 1459.2 x60: 5.7 x64: 0000 insideTempRC: 0 x72: 0200 x76: 0000 onHysteresisNo: 0 offHysteresisNo: 1 hcBoosterStage: 0

The "x08: FF4D" looks strange here, as well as the "normal roomSetTemp: 1459.2" and following 3 parameters ("x64", "x72", and "x76"), at least I wonder about these parameters' names. Do they mean parameters P64, P72, and P76?

In your code for version 2.16 you should use the parsing for sHC1 like version 2.06

Thank you! Now I have lots of information and kind hints from all of you to try something and report back. Please bear with me, as it will take a few days.

I would like to use the nonblocking function because of my older system/firmware and lots of "too slow" messages in the log. I already set the baudrate both in /etc/ser2net.cfg and in fhem to 9600.

Das Feature wird über zwei Attribute im Modul THZ gesteuert:
1. Das Atrribut "nonblocking" schaltet das Feature ein/aus (1=ein, 0=aus). Standartmäßig, d.h, wenn das Attribut nicht vorhanden ist, ist das Feature ausgeschaltet. Man hat also dann das gewohnte Verhalten.
2. Das Attritut "simpleReadTimeout" legt die Zeit fest, die Maximal auf eine Antwort von der THZ geartet wird. Hier kann man den optimalen Wert ausprobieren. Je höher der Wert, desto weniger Fehlermeldungen sollten im Logfile erscheinen. Bei mir habe ich den Wert auf 8 sec. gesetzt. Hinweis: Die Wartezeit wir intern begrenzt, falls das nonblocking nicht auf 1 gesetzt wurde. Damit wird verhindert, dass THZ blockiert.

These 2 attributes do not seem to "stick" when the fhem service is restarted. Is this intended, or do I have some problem here?

Furthermore, I have a question about the below Perl warning inthe log: What is this about?

2020.06.19 13:01:57 1: PERL WARNING: Use of uninitialized value in concatenation (.) or string at ./FHEM/00_THZ.pm line 982.

I use quote instead of code tags below, because with code tags I cannot highlight in 00_THZ.pm the line (982) in question:
