# TITLE: GARAGE DB CONTROLS
# zorruno.com layout v1.1 2026
#:########################################################################################:#
# REPO:
# https://home.fox.co.nz/gitea/zorruno/zorruno-homeassistant/src/branch/master/esphome/esp-garagedbcontrols.yaml
#:########################################################################################:#
# VERSIONS:
# v1.2 2026-03-03 EV monitoring updated to match Device A:
# - Rolling average EV power (default 5 min @ 10s)
# - EV charging binary sensor (threshold configurable)
# - EV totals and energy summaries (today/yesterday/month/year)
# v1.1 2026-02-25 Updated yaml to zorruno layout V1.1
# v1.0 2025-10-23 Initial Version
#:########################################################################################:#
# HARDWARE:
# - Sonoff 4CH R2 (ESP8266 / ESP8285)
# - Reference YAML: https://github.com/jvyoralek/homeassistant-config/blob/master/esphome/sonoff-4ch.yaml
# - Relays (4CH R2): GPIO12, GPIO5, GPIO4, GPIO15
# - Buttons (4CH R2): GPIO0, GPIO9, GPIO10, GPIO14
# - Status LED: GPIO13 (active-low)
# - Extras (as used here):
# - EV pulse input: GPIO2 (must be HIGH at boot; INPUT_PULLUP used)
# - DHT sensor: GPIO3 (note: UART RX pin on ESP8266; ensure logger baud_rate=0)
#:########################################################################################:#
# OPERATION NOTES:
# - Provides 4 relay outputs with matching local buttons.
# - Relay restore modes are set per-output (some default ON, some default OFF).
# - EV charger monitoring (2 Wh per pulse on GPIO2):
# - Lifetime total energy (kWh) from persisted absolute pulse total.
# - Rolling average power (default 5 min) to reduce spiky readings at low load.
# - Charging binary sensor based on averaged power threshold.
# - Energy summaries: today, yesterday, this month, last month, this year, last year.
#:########################################################################################:#
# OFFLINE NOTES:
# a) Home Assistant OFFLINE, WiFi OK
# - Device continues relay/button operation and continues pulse counting locally.
# - API/MQTT publishing will fail until HA (and/or broker) is back.
# b) MQTT OFFLINE (or broker unreachable)
# - Relays/buttons still operate locally and via HA API (if HA is available).
# - MQTT state publishing depends on broker.
# c) Entire WiFi/Network OFFLINE
# - Accurate time IS needed for daily/monthly/year rollovers (SNTP required for correct period boundaries).
# - Loss of network will drift the timeclocks; time of day can be reset by powering off then on again at 12pm (midday)
