+# HA recorder exclusions for the eg4-battery daemon's MQTT entities.
+#
+# Merge with your existing recorder config; if you don't have one, this whole
+# file can be referenced as  `recorder: !include eg4_battery/recorder.yaml`.
+#
+# Rationale:
+#   - register_NN entities are raw Modbus registers, diagnostic only
+#   - individual cell voltages are redundant once you have min/max/delta
+#   - uptime / version / static config values are pure noise in a timeseries
+#
+# Everything NOT in `entity_globs` below keeps recording normally, including
+# the Tier-1 (pack_voltage / soc / soh / cycle_count / cell_voltage_min/max/
+# delta_mv / capacity_ah) and Tier-2 (warnings / protections / error_code)
+# entities. See ../NOTES.md for the retention-tier breakdown.
