Eve Weather not showing temperature state

Hi all,

so I included my new Eve Weather sensor with Google Home (Nest Hub 2 as a border router) and then added a new Matter device to my C8 Hub, v2.4.2.157, using the code GH provided.
Seemed to work fine so far, until I found that the temperature state was not shown.

During troubleshooting I did a reset of the device severel times, also tried when first including with my Home Pod Mini, no dice.
I am using the default Hub driver, firmware used is 3.5.0, any ideas, anyone?

Edit: Here's an excerpt from the logs, maybe the Java error could be a clue?
