Hi immi,

I re-engineered the register of my firmware. Could you please test and apply the patchfile.

The response message for Register FB in my firmware is shorter. Therefore I commented out the parsing elements which are out of the message, otherwise I got error messages in the log file.

Thanks
Andre

[immi]

Hi Andre
excellent patch!!
I will check it this evening carefully.
I do not want to change the order of FB, because I would like that people exchange their basic plot configuration.
The warning about message lenght will be fixed like this
[" actualPower_Qc: ",      50, 8, "n.a.", 1],   [" actualPower_Pel: ",      50, 8, "n.a.", 1],

FHEM is loaded onto a Win8.1 64 bit, Strawberry Perl 5.20.1.1-32bit
I connect the heatpump (LWZ403) via usb2ser.
The software of the heatpump is 2.36.
Can you help me?

[immi]

Hi    brinkmicha
happy you want to join us

6 comments from my side:

• you can ignore all "experimental" warnings
• never tested fhem on windows: dont´t you have a unix computer? I mean: do you really want to run your win8 24h/day? Is not cheaper a RASPI?
• what is usb2ser? a normal direct connection with a USB dongle?
• have you used "attr Mythz firmware 2.06"  in config file?
• please post your config file
• which THZ-FHEM version are you using? The current is 0.127

immi

[brinkmicha]

Hi immi,
my Win8 is on a Zotac ID86 -> 10W. I use the system for the Stiebel and Solaredge Software.
There is no USB or LAN Port on my LWZ403sol from 2008. So I use the Serial Port like Robert Penz http://robert.penz.name/heat-pump-lwz/.
I use the THZ-FHEM version 0.127.
No, I have not used "attr Mythz firmware 2.06"  in config file...  where it must be entered?
Here is the config...

Thanks

Hi immi,
behave the same...   

if it is behaving the same (you have problem with p03RoomTempStandbyHC2SummerMode), it means you have not done what I said correctly --> "attr Mythz firmware 2.06"

if it is not behaving the same, post the logs

Hi immi,
I aggree with you, we should not change the order of values in the readings. I fix it in your way.
Another problem is line#1137

Code Auswählen Erweitern

$parsingcmd = substr($message,2,6) if ($parsingcmd =~ m/(0A|0B|0C)/) ;
In Firmware 2.x the command is always 1 Byte. Could you add the condition like "firmware" ne "2.06"?
Thank You.

Hi immi,

great, it works perfect.

uploaded v0.128 tomorrow you can update

Hi immi,

behave the same... 

more ideas? 

brinkmicha

Du solltest zuerst wissen, ob überhaupt die Kommunikationsstrecke ok ist => eine Fehlerquelle ausschließen. Wenn Du den HeatpumpMonitor erwähnst, dann kennst Du ja den grundsätzlichen Ablauf der Kommunikation. Das kannst Du mit einer Terminalsoftware testen.  Was Robert Penz nicht erwähnt: zwischen Antwort der LWZ und dem nächsten Befehl muss ein Zeitfenster von min.10, max. 500ms eingehalten werden.

Unter Windows kannst Du dieses Terminal https://sites.google.com/site/terminalbpp/ verwenden, um direkt mit der LWZ zu "reden". Durch seine Makrofähigkeit kann man das Zeitfenster in Form von Delays berücksichtigen. Ein Makro, um sGlobal abzufragen, wäre dann

$02%DLY0010$01$00$FC$FB$10$03%DLY0010$10

Die Firmwareversion erhältst Du mit

$02%DLY0010$01$00$FE$FD$10$03%DLY0010$10

Wenn Du damit Antworten bekommst (im ersten Fall den größeren Datenblock, im zweiten Fall einen kürzeren, jeweils im Hex-Format), dann stimmt Deine Kommunikation zwischen PC und LWZ.

[immi]

Hi brinkmicha

I think I understood where  the problem with Windows is
https://github.com/mhop/fhem-mirror/blob/master/fhem/FHEM/DevIo.pm
# NOTE2: This works on Windows only for TCP connections
Sub DevIo_SimpleReadWithTimeout($$)
Sub DevIo_TimeoutRead($$)

I do not know if it can be fixed, but let´s try.
Please update to v0.128
Please change line 768 of 00_THZ.pm

Code Auswählen Erweitern

my $buf = DevIo_SimpleReadWithTimeout($hash, 0.7);

with

Code Auswählen Erweitern

select(undef, undef, undef, 0.025); # this is a delay of 25ms
my $buf = DevIo_DoSimpleRead($hash);


then start fhem with option "attr Mythz firmware 2.06"
after that post your complete log as file
