MCZ Musa Hydromativ from 2020

[Modsk]

Hello everyone,
I use a MCZ Musa Hydromatic from 2020 and have just installed this integration via HACS. First of all, thank you very much! Works right away in the basic functionalities.
Now the Musa Hydromatic is a water-bearing pellet stove that behaves slightly differently than the standard pellet stoves.

1. It is controlled not only via the living room temperature but also via the buffer temperature. The buffer temperature is also read out, just like the water temperature, but not the target temperature.
2. There is also a boiler target temperature that is not read out.
3. The fan control seems to be different. Automatic - level 1-5... nothing is read out here either.
4. Chrono program... The time control when the oven runs etc...
   These are just a few points that I noticed spontaneously. I would like to support and promote this project and maybe there are other people with this oven.
   Unfortunately, I am not a programmer, but I am happy to support within the scope of my possibilities and am happy to test or provide information.
   Thanks again.
   Regards,
   Stefan

Hi, @Modsk,

Can you add the diagnostics file from the integration here ?

With this I'll be able to see specific things related to your exact model.

Kind regards,

Robbe

Hi Robbe-B,
Thank you for your feedback.
Added diagnostic data in the first post.
And of course also added a star for this repo :-)

@Modsk,
I'm very glad you've added the diagnostics file, can you maybe post screenshots of different screens in the official MCZ app and attach a diagnostics file from the same moment from the screenshots ?

I'm also still trying to understand your setup with buffer, boiler, stove, .....
Can you maybe provide me with more information about that ?
Maybe a simple diagram ?

I need to fully understand every single value of your setup in order to properly build support for it since there is no public documentation from MCZ.
Kind regards,
Robbe

Hi Robbe,
Here are some screenshots from the MCZ app and the description of my heating system. The pellet stove is not the primary heating system, which is why I probably only use a fraction of the functions. I hope this helps anyway.
Enclosed is the diagnostic file again.
If I can help in any way or provide input, please let me know. I will do my best.
Regards, Stefan

@Modsk,
Some followup questions.
Am I correct to say, there is no possibility to on/off the boiler or puffer individually ?
Also what does this winter thing mean ?

Kind regards,
Robbe
