Unable to get changeset ID

[Erwann Penet]

Hi,

I am having difficulty retrieving configuration values from my Vitosolic
200 controller.

I have tried the customizer sample, but I get "WARNING: Unable to create
optimizer for master with address 0x7321"

I have tried the customizer2 sample, but I get "Unable to get changeset,
using 0 as default" and I don't know what to put in the job for tank
priority ("Vorrang_Sp1" 0x1000 and ""Vorrang_Sp2" 0x1001) and for manual
pump relay ("Relaismodus1" 0x01F1 and "Relaismodus4" 0x01F4)

Now I have tried the vbus-parameterization documentation code from
https://danielwippermann.github.io/resol-vbus/#/md/docs/vbus-parameterization
and I get stuck again with "Error: Unable to get changeset ID"

> node parametrization.js
> - `0xAA 0x00 0x00 0x21 0x73 0x20 0x00 0x05 0x00 0x00 0x00 0x00 0x00
> 0x00 0x00 0x46`
>     - destination address = `0x0000`
>     - source address = `0x7321`
>     - command = `0x0500`
>     - 16-bit parameter = `0x0000`
>     - 32-bit parameter = `0x00000000`
> Error: Unable to get changeset ID
>     at main (/home/pi/resol-vbus/parametrization.js:65:15)

Any help to read and write the configuration values for those two would
be greatly appreciated.

Regards,
