THZ 404 Raumtemperatur und Feuchte auslesen

[sensorle]

Hallo,
ich habe eine THZ 404 SOL mit Kühlfunktion.
Wegen der Kühlfunktion habe ich eine zweite Steuerungseinheit im Erdgeschoss.
In dieser Steuerungseinheit ist noch ein Temperaturfühler und ein Feuchtemesser integriert.
Die aktuelle Raumtemperatur und die Luftfeuchte im Raum lasse ich mir auf dem Display auch anzeigen.
Im Display lauten die Namen: "Luftfeuchte HK2" und "Raumtemperatur HK2"
Diese beiden Werte würde ich auch gerne mit FHEM loggen. Nur leider finde ich die nirgens.

Der Parameter "relHumidity" in sGlobal steht konstant auf 0
Der Parameter "insideTemp" in sGlobal steht konstant auf -60

Kann mir da bitte jemand helfen?

Danke.

Hi Sensorle
I do not have any secondary display nor the 404.
To my knowledge, Sglobal register shows data from HK1 and not HK2.
Probably someone has already addressed your topic in https://forum.fhem.de/index.php/topic,33452.0.html
search and read the 140 pages    
if you find nothing, ask directly in the https://forum.fhem.de/index.php/topic,33452.0.html

p.s. Maybe you can easily change the setting of your heatpump so that in display you see "Luftfeuchte HK1" und "Raumtemperatur HK1"

Hi immi,
yes I know, the same problem was posted before. I realized it too late. Sorry for double post!
https://forum.fhem.de/index.php/topic,33211.msg561043.html#msg561043

Meanwhile I download the registers with the command

Code Auswählen Erweitern

get Mythz debug_read_raw_register_slow

and tried to debug - but without success.
I tried different things like adding an offset to some values, changed high-byte and low-byte.
I even heated up the 2nd display with a hair-dryer to and compared the values that did change...

Changing to HK1 probably will work, but I think I have to stay and HK2 for the cooling function?!
At least this is what the technician told me when installing the heat pump 6 years ago - if I remember it right.

Btw.:
I did not get 255 lines in the data file like you described here:
https://forum.fhem.de/index.php/topic,33452.msg526493.html#msg526493
Though I think the important registers are available, like F4 and F5

Is there a way to read more registers 0...255 where this data (temp. and humidity) may be "hidden"?

Thank you

no problem

yes have a look at code starting from sub THZ_debugread($){
there is lots of commented code.... which is quite selfexplaining
e.g. you can swap line 1914 with 1915
or use 1927 with 1919...

there are lots of people in forum with your cooling  tecalor just ask them directly
