Description
I am experiencing issues with specific eBUS messages, using micro-ebusd features, on my Vaillant aroTHERM plus VWL 155/6 A system. While Hmu-YieldHc reports correctly, other related energy and yield values are either incorrect or missing when accessed via API/HTTP GET.
Device Info:
• Chip ID: 9c139ed6221c (ESP32-C6, rev 2)
• Hostname: ebus-d6221c
• Firmware: 20260208 (latest version tested)
• Heat Pump: Vaillant aroTHERM plus VWL 155/6 A 230V
Per il resto grazie, valorizzando la temperatura di mandata sono riuscito a ridurre i pendolamenti della pompa di calore SOVRADIMENSIONATA. Saluti e buon lavoro.

Actual behavior
When requesting data via API or browser GET:
Hmu-YieldHc: Correct.
Hmu YieldHwc: Reports a constant or incorrect value of "40".
ctl_v3 PrEnergySumHc: No value (null/empty).
ctl_v3 PrEnergySumHwc: No value (null/empty).
I have already updated the firmware to version 20260208, but the issue persists. I am attaching screenshots of the JSON responses for reference.








Expected behavior
All requested energy and yield messages (Hmu YieldHwc, ctl_v3 PrEnergySumHc, ctl_v3 PrEnergySumHwc) should return their respective current values from the heat pump, similar to Hmu-YieldHc.
