Adding Inverter BKW850-V2 but missing all datapoints

[koogle1]

I am trying to connect my solar inverter BKW850-v2 in a Home Assistant setup.
The device is correctly detected (ID, Address; Secret) but I get the following error message when trying to add entities (here: 2 - total energy, 3 - actual power provided, 4 - actual temperature):
"Connection to device succeeded but no datapoints found, please try again. Create a new issue and include debug logs if problem persists."

Provide details about your environment.
--> see attached file config_entry-localtuya-01JDT7JX4S9VZ1AJ8VECY8VYGW.json

• [partially; power scale wrong; temperature missing] Does the device work using the Home Assistant Tuya Cloud component ?
• [not tested] Does the device work using the Tinytuya (https://github.com/jasonacox/tinytuya) command line tool ?
• [not sure; it ws working before but the version was not older than 5.2.1 and a downgrade to that version did not work either] Was the device working with earlier versions of localtuya ?
• [x - all working there] Are you using the Tuya/SmartLife App in parallel ?

not sure where to implement those logger.set statements and what file to record; could not load configuration.yaml with statements inside :-(
