# TITLE: BEDROOM 3 LIGHTSWITCH
# zorruno.com layout v1.1 2026
#:########################################################################################:#
# REPO:
# https://home.fox.co.nz/gitea/zorruno/zorruno-homeassistant/src/branch/master/esphome/esp-bedrm3lights.yaml
#:########################################################################################:#
# VERSIONS:
# V3.6 2026-03-05 Updated yaml to zorruno layout V1.1
# V3.5 2025-07-24 YAML tidyups
#:########################################################################################:#
# HARDWARE:
# - Zemismart KS-811 Double push button (KS-811-2)
# pinout/schematic: https://community.home-assistant.io/t/zemismart-ks-811-working-with-esphome/
#:########################################################################################:#
# OPERATION NOTES:
# - Virtual 2-button wall switch used to control Bedroom 3 ceiling fan light and to force "all off"
# - Button 1 toggles the iFan02 light (sends MQTT ON/OFF), using Relay 1 as the local state mirror
# - Button 2 forces "All Lights Off" (turns iFan02 light OFF and sets fan speed to 0), and turns Relay 2 OFF
# - Relay 1 and Relay 2 are used as local state indicators (no load connected)
# - A short cooldown is used on Button 1 to prevent repeated MQTT publishes
#:########################################################################################:#
# MQTT COMMANDS:
# Remote fan light command:
# ${mqtt_remote_device_command_topic1} -> ON,OFF
# Remote fan speed command (used by All Off):
# ${mqtt_remote_device_command_topic2} -> 0
#
# Remote fan light status (subscribed to keep Relay 1 in sync):
# ${mqtt_remote_status_topic1} -> ON,OFF
#:########################################################################################:#
# OFFLINE NOTES:
# a) Home Assistant OFFLINE, but Network and MQTT ONLINE
# - Buttons still publish MQTT commands directly to the remote iFan02 (light and all-off actions)
# - Relay 1 state mirror still updates from subscribed remote light status topic
# b) MQTT OFFLINE (but WiFi/Network and HA API ONLINE)
# - Buttons cannot control the remote iFan02 (control path is MQTT)
# - Relay 1 will not mirror the remote light status while MQTT is down
# c) Entire WiFi/Network OFFLINE
# - No MQTT publish/subscribe and no HA API connectivity
# - Buttons will not control the remote iFan02
# - Local indicator relays remain in their last state until connectivity returns (or reboot)
# - Accurate time is NOT needed (SNTP not required) for core operation
