How to connect to my arkteos/ajtech heat pump

Configuration
1

Hi,

I would like to integrate my heat pump to HA.
It is an Arkteos Zuran 3. Based on external module Mitshubishi, and an AJtech internal module.
2 zones controlled by 2 RF thermostats.
I got a web monitoring through ethernet.But it is Java app.
I got an private IP address with 3 ports (http, IHM, Applet).
But I cannot read anything.

I am looking for how to integrate data (sensor, climate) to HA.
I do not find anything on docs, or on Google about it, except ajtech and jeedom on the Jeedom forum…
But it does not help me.

The fact that it has web control via the Java applet means there is very likely an API. If you can find some information on this you could control the heat pump via rest commands and rest sensors.

Thanks Tom_i
I open, with jd-gui, the pac control app Jar file on my Windows.
A lot of class files with huge data
Too much. I tried to find something to help me to begin.
But too much difficult.

Or maybe that class : S_GESTION_CASCADE_MODBUS talk about Modbus…

Or those data :

this.V.sCyc_Ethernet.Port_applet = 9651;
this.V.sCyc_Ethernet.Port_ihm = 9641;
this.V.sCyc_Ethernet.Port_http = 8581;
this.V.sCyc_Ethernet.Port_sent = 9661;

What port_sent means ? Push commands ?

You can do it with modbus… with extra board. See PM

Hi
I own an Arkteos REG3 heat pump and was able to decode some values.
I’ve just uploaded the code on my Github repo

Hi, I’ve also a arkteos zuran3 with some heaters.
I’m thinking about to changes heat of radiators for trv sonoff and use versatile thermostat (which I already use for Electric radiators).
Do you know how to configure arkteos to use it ?

Thanks.
