 # VERSIONS:
+# v1.4 2026-07-12 Added Home Assistant Energy Dashboard metadata.
+#      Marked cumulative PZEM, mains total, and 32A Wallcharger total energy
+#      sensors as energy / total_increasing.
+#      Marked mains and EV power sensors as power / measurement.
+#      Added single-process compilation limit to reduce Builder memory use.
 # v1.3 2026-02-25 Updated yaml to zorruno layout V1.1
 # v1.2 2026-02-25 Updated yaml to zorruno layout V1.1. Added EV charging binary sensor
 #      and EV power rolling average (default 5 min). Clarified EV pulse notes.

 # OPERATION NOTES:
 # - Power Monitor using 3x PZEM-004T V3 (Modbus) for 3-phase monitoring
 # - Pulse input energy monitoring for 32A EV Charger (2 Wh per pulse)
+# - 32A Wallcharger Total Energy is cumulative pulse-derived energy in kWh
+# - Cumulative active-energy sensors are exposed to Home Assistant with:
+#     device_class: energy
+#     state_class: total_increasing
+# - This allows the cumulative totals to be selected in the HA Energy Dashboard
 # - Adds a 5 minute rolling average for EV power to avoid spiky readings at low loads
 # - Adds a binary sensor to indicate when the EV charger is operating (threshold configurable)
