# TITLE: LOUNGE SOUTH LEFT LIGHTSWITCH
# zorruno.com layout v1.1 2026
#:########################################################################################:#
# REPO:
# https://home.fox.co.nz/gitea/zorruno/zorruno-homeassistant/src/branch/master/esphome/esp-loungesouthleftswitch.yaml
#:########################################################################################:#
# VERSIONS:
# V4.1 2026-03-11 Updated yaml to zorruno layout V1.1
# V4.0 2025-10-04 Copied from other device
#:########################################################################################:#
# HARDWARE:
# - Zemismart KS-811 Double push button
# - ESP8266 based
# - pinout/schematic:
#   https://community.home-assistant.io/t/zemismart-ks-811-working-with-esphome/
# - Relay 1 output on GPIO13
# - Relay 2 output on GPIO12
# - Button 1 input on GPIO16
# - Button 2 input on GPIO5
# - Status LED on GPIO2
#:########################################################################################:#
# OPERATION NOTES:
# - Lounge South Left switch with 2 outputs:
#   1) Wall Washer Left
#   2) Outside Light 1
# - Button 1 toggles Relay_1 locally
# - Button 2 toggles Relay_2 locally
# - Relay_2 is synchronised with a remote MQTT device:
#   - Remote device name: garage-corridor-lights
#   - Remote ON/OFF commands are mirrored locally
#   - Local Relay_2 ON/OFF changes are published back to the remote topic
# - A guard flag is used to prevent MQTT feedback loops when Relay_2 state changes originate remotely
#:########################################################################################:#
# MQTT COMMANDS:
# - Remote command topic:
#   - ${mqtt_remote_command_topic}
# - Remote status topic:
#   - ${mqtt_remote_status_topic}
# - Payloads used:
#   - ON
#   - OFF
#:########################################################################################:#
# OFFLINE NOTES:
# a) Home Assistant offline (network and MQTT online):
#    - Local button control continues to operate both relays
#    - Relay_2 MQTT sync with the remote device continues if MQTT broker is online
#
# b) MQTT offline (or HA/MQTT offline):
#    - Local button control continues to operate both relays
#    - Relay_2 sync to the remote MQTT device is unavailable
#
# c) Entire WiFi/Network offline:
#    - Local button control continues to operate both relays
#    - Relay_2 sync to the remote MQTT device is unavailable
#    - Accurate time is not needed; SNTP is not required for operation
