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

[immi]

Thanks for the hint. sHC1.opMode is the right one:
==> standby in case of vacation
==> setback in normal case

==> standby in case of vacation
==> setback in night case (nightabsenkung)
==> normal in normal case (day-normal)

setback and normal of sHC1.opMode are determined by programHC1_xxx, probably.
I do not know what happens, if you have different  times for programHC1_xxx and programFan_xxx

Hi Karl
It looks like you tecalor is busy and ansers very late.
I jut uploaded version 0.152 introducing a delay for you.

update fhem tomorrow; restart and tell me if you seen an improvement.

Hi Immi,

I updated the module and restartet FHEM, now it looks, that i have even more of this errors (nearly every minute, in the past it was ~20 minutes).

So this did not solve the issue.

Hi Karl
this makes no sense: are you using windows?
if your fhem is running on unix, change  line 1142c0f 00_THZ.pm 

$buf = DevIo_SimpleReadWithTimeout($hash, 0.7) if(!defined($buf)) ; #added for Karl Antwort msg468515

[Karle]

no it is running on linux (debian based on odroid C2).

I will try to change the file.

Karl

Edit: File changed ... restart ... I will check the log later or tomorrow

[Karle]

I checked the logfile today, the message did not appear.

The only thing I saw two times was the following:

2016.07.05 09:02:13 1: /dev/ttyUSB1 disconnected, waiting to reappear (Mythz)
2016.07.05 09:02:15 3: Setting Mythz serial parameters to 115200,8,N,1
2016.07.05 09:02:15 1: /dev/ttyUSB1 reappeared (Mythz)

greets Karl

Hi Karle
ok please devide the 2 problems
I try to explain you what happens:
by adding line 1142 with 0.7, you just ask fhem to be more patience and wait 0.5+0.7 seconds before complaining of the tecalor and drop the comunication..
the question is why your tecalor needs so much time to react sometimes, and what is the microcontroller of your tecalor doing all the time

the reconnect/connect issue can be ignored; I have no solution

[Karle]

I also think the connect/reconnect is no problem. It appears 1-3 times a day for some seconds.

With the bigger delay the other message disappeares. Why my LWZ has this high delay I don't know. There is everything standard. Maybe I have another firmware than your machine.

In the past with the slow raspberry Pi I did not have this problem so much, maybe the faster odroid is the reason for that.

But it seems all fine now.

have you tried to reduce the speed to 57600bps? maybe the messages are just too fast?

[Karle]

have you tried to reduce the speed to 57600bps? maybe the messages are just too fast?

no not yet, do you use the 57600 bps ? I don't know why it is set to 115200.

[immi]

no not yet, do you use the 57600 bps ? I don't know why it is set to 115200.

Also mine is set to 115200; I do not know why and I do not know if it can be changed or it is hardcoded.

[micomat]

Just a guess, I've had some modem issues in the early computer years where 115200 which is double 57600 was a problem for some controllers

[willybauss]

As far as I remember we had this topic in the past some times, and in none of all cases it was possible to access the THZ with different baud rates. So I still believe it's hard coded.

[mlb]

IMHO it depends on cable quality and length - in my case the cable has about 5 meters and with 115200 it had problems, and after reducing the speed it has been working fine and very stable.

Hallo,
mit der neuesten Version 0.152 laufen plötzlich die Messwerte für Aussen-, Vorlauf-, Rücklauf etc. von der FHEM Installationsanleitung für das THZ-Modul nicht mehr. Bei mir war es so, dass die letzten Werte vom 22. Juli waren, vermutlich dem Tag, an dem ich ein Update auf FHEM gestartet habe. Ich habe das Modul noch mal von vorne nach Anleitung konfiguriert, leider erscheinen die Werte in der Tabelle jetzt überhaupt nicht mehr. Leider habe ich keinerlei Informationen gefunden, was sich da geändert hat und wie ich die Werte wieder einlesen kann. Kann mir hier bitte jemand helfen?

Ich beziehe mich auf diese Anleitung: http://www.fhemwiki.de/wiki/Tecalor_THZ_Wärmepumpe

Gruss,
Thomas.

normalerweise postet immi hier immer welche aenderungen in den versionen erfolgt sind.
was sagt denn dein THZ-log in fhem? irgendwelche fehlermeldungen?
