Missing grid readings with SK_HWR 6 (Fox ESS H3 6.0 E equivalent)

[m2key1]

Environment

• Release: 1.12.2
• Hardware: SK_HWR 6 (equivalent to H3 6.0 E)
• Communication: Waveshare RS485 to PoE RJ45 module
• Versions:
  • Master: 2.01
  • Slave: 1.03

Description

After setting up the Home Assistant integration, PV string values are reporting correctly, but I'm unable to get any readings for:

• Grid consumption
• Feed-in data
• Other grid-related metrics

Notably, the Fox ESS Cloud integration works and provides all grid-related information correctly.

Behavior

• PV string values report correctly
• No grid-related readings are visible
• No errors or faults during integration setup or in logs
