# TITLE: OFFICE DUAL LIGHT CONTROL
# zorruno.com layout v1.1 2026
#:########################################################################################:#
# REPO:
# https://home.fox.co.nz/gitea/zorruno/zorruno-homeassistant/src/branch/master/esphome/esp-officeduallights.yaml
#:########################################################################################:#
# VERSIONS:
# V2.7 2026-04-24 Updated MQTT local topics, retain false, and timed control using seconds
# V2.6 2026-04-23 Added independent MQTT timed ON control for relay1 and relay2
# V2.5 2026-03-11 Updated yaml to zorruno layout V1.1
# V2.4 2025-06-30 Tidied up MQTT direct relay control (esps can control each other via MQTT)
# V2.3 2025-06-18 Added MQTT direct relay control
#:########################################################################################:#
# HARDWARE:
# - Sonoff Dual R1
# - ESP8266 based
# - 2 x relay outputs
# - 2 x local push buttons
# - Relay control via UART serial commands
# - Status LED on GPIO13
#:########################################################################################:#
# OPERATION NOTES:
# - Controls 2 office light circuits:
# - Overhead cool white lights
# - Right hand warm bunker light
# - Local button 1 toggles relay/light 1 and cancels any active timer for relay 1
# - Local button 2 toggles relay/light 2 and cancels any active timer for relay 2
# - Relay state changes are sent out via MQTT status topics with retain false
# - MQTT can command each relay with:
# - On = turn on with no timer and cancel any active timer
# - Off = turn off immediately and cancel any active timer
# - 1 to 3600 = turn on for that many seconds, then turn off
# - If a new valid timed value is received while a timer is already active, the timer restarts from zero
# - Invalid MQTT timer values are ignored
# - Template binary lights drive the template relay switches
# - Sonoff Dual R1 requires UART serial packets to operate the physical relays
#
# MQTT COMMANDS:
# - Command relay 1:
# - ${mqtt_local_command1_topic} On, Off, or 1 to 3600 seconds
# - Command relay 2:
# - ${mqtt_local_command2_topic} On, Off, or 1 to 3600 seconds
# - Relay 1 status publishes to:
# - ${mqtt_local_status1_topic} On or Off
# - Relay 2 status publishes to:
# - ${mqtt_local_status2_topic} On or Off
#:########################################################################################:#
# OFFLINE NOTES:
# a) Home Assistant offline (network and MQTT still online):
# - Device continues to operate from local buttons
# - Device can still be controlled directly by MQTT
# - Relay status still publishes by MQTT if broker is available
#
# b) MQTT offline (or HA and MQTT both offline):
# - Device continues to operate from local buttons only
# - No direct inter-ESP MQTT control available
# - No MQTT state feedback available
#
# c) Entire WiFi / Network offline:
# - Device continues to operate from local buttons only
# - No HA control or MQTT control/status available
# - Accurate time is not needed; SNTP is not required for operation
