# TITLE: LAUNDRY DRYER MACHINE POWER
# zorruno.com layout v1.1 2026
#:########################################################################################:#
# REPO:
# https://home.fox.co.nz/gitea/zorruno/zorruno-homeassistant/src/branch/master/esphome/esp-laundrydrypow.yaml
#:########################################################################################:#
# VERSIONS:
# V1.2 2026-07-12 Added cumulative Load Energy integration sensor
# Added seven-day maximum power sensor
# Maximum power resets after 168 powered hours
# V1.1 2026-03-11 Updated yaml to zorruno layout V1.1
# V1.0 2025-05-28 Initial Version
#:########################################################################################:#
# HARDWARE:
# - Sonoff POW R1
# - ESP8266 based
# - HLW8012 power monitoring
# - Single relay output
# - Blue status LED on GPIO15
# - Local push button on GPIO0
# - Relay output on GPIO12
# - Reference: https://devices.esphome.io/devices/Sonoff-POW-R1
#:########################################################################################:#
# OPERATION NOTES:
# - Monitors dryer load current, voltage, power, and cumulative energy
# - Load Energy integrates measured power over time and reports kWh
# - Load Energy resets to zero if the ESPHome device reboots
# - Home Assistant handles the reset because the sensor uses total_increasing
# - Load Maximum Power 7 Days records the highest measured power
# - Maximum power resets after 168 powered hours
# - The maximum power value and elapsed-hour counter are retained across reboots
# - The elapsed-hour counter is saved every six hours to reduce flash writes
# - An unexpected power loss may extend the reset period by up to approximately six hours
# - No accurate clock or SNTP connection is required for the seven-day reset
# - Provides a virtual relay switch that controls the physical relay and LED together
# - Local button toggles the virtual relay switch
# - On boot, the virtual relay is turned ON
# - "Load Running" turns ON when measured power is above 4 W
# - "Load Running" uses delayed_off: 15s to avoid rapid state changes
#:########################################################################################:#
# OFFLINE NOTES:
# a) Home Assistant offline (network and MQTT online):
# - Device continues running normally
# - Local button still works
# - Power, energy, running state, and maximum power continue operating locally
# - MQTT remains available if the common MQTT package is enabled and broker is reachable
#
# b) MQTT offline (or HA/MQTT offline):
# - Device continues running locally
# - Local button, relay control, LED control, and power monitoring still work
# - Energy integration and maximum power monitoring continue locally
#
# c) Entire WiFi/Network offline:
# - Device continues running locally
# - Local button, relay control, LED control, and power monitoring still work
# - Energy integration and maximum power monitoring continue locally
# - Accurate time is not needed; SNTP is not required for operation
