Control Daikin Altherma Heat Pump via NodeRed

Dear all,

is anybody running an Daikin Altherna Heat Pump logged or controlled by a local Node-Red installation ?
I got mine several days ago and now I am trying to get control over it via Node-Red.

I know that there is a Node that allows connection to the Daikin Cloud, but I was unable to find out if this is a read-only access or if it is possible to even set certain parameters !?
Unfortunately the documentation is not that good ...

But I ask myself if there is another possibiliy - like reading and setting data directly using LAN or WLAN ?

Would be really nice to discuss with somebody having this solution already in place.
