Uponor U@home and node red

Building a central monitoring and so far I made implementation of Nilan (CTS 602) ventilation and NETIO power management (both Modbus interfaces).

Pending is to stitch in the room temperatures from Uponor U@home to node red and my skills are a bit limited.

The Uponor UI renders perfect with a browser and I have learned that fetching the temperatures should be possible.

As far as I have been able to find JSON is the protocol to be used to get the PV (Actual temperature) of each room. This is the main value I am looking for.

Anyone with knowledge and skills?
