+# SMART DIN POWER MONITOR AND RELAY (Originally CBU)
+# V1.0 2025-08-26 Initial Version
+##########################################################################################
+# Ex Tuya Smart Relay
+# Uses this chip for power monitoring BL0942
+# Replacement https://templates.blakadder.com/ESP8685-WROOM-06.html
+#
+# NOTES
+# - DIN rail power monitor and relay
+# - Relay is a pulse to latch ON (GPIO04) and pulse to latch OFF (GPIO05)
+# - Has an "is it running" template sensor with a minimum wattage value of ${min_power_to_state_running_default}
+# - The relay opens on over-current at ${max_current_trip_default} (Trip Active sensor set). Trip is latched
+#   (relay stays OFF) until manually reset via the "Clear Trip" button or you toggle the relay ON again.
+# - The status_led flashes with a speed depending on current (faster near limit).
+# - The status_led is ON when the relay has tripped
+# - Inrush debounce: current must remain above the trip threshold for ${overcurrent_debounce_ms} ms
+#   before the trip occurs (helps ignore short inrush spikes).
+# - Energy totals calculated on-device:
+#     * Last Hour Energy (kWh) – snapshot of the previous completed hour
+#     * Today / Yesterday (kWh) – resets at local midnight, survives reboots
+#     * This Week / Last Week (kWh) – resets at Monday 00:00 local time, survives reboots
+#     * This Month / Last Month (kWh) – resets at 1st of month 00:00 local time, survives reboots
+# - For rolling 24h Min/Max Power, use HA "Statistics" helper instead of on-device buffers.
