# REPO:
# https://home.fox.co.nz/gitea/zorruno/zorruno-homeassistant/src/branch/master/esphome/esp-laundrylights.yaml
#:########################################################################################:#
# VERSIONS:
# V3.7 2026-04-24 Reviewed MQTT timer control, corrected notes, added local MQTT status publishing
# V3.6 2026-03-11 Updated yaml to zorruno layout V1.1
# V3.5 2025-07-24 YAML tidyups
# V3.0 2025-06-05 YAML tidyups
# V2.0 2025-06-01 Was initially a 3 button switch, now 2
# V1.0 2025-05-30 Initial Version
#:########################################################################################:#
# 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:
# - Button 1 toggles Relay 1 for the laundry lights
# - Button 2 single click toggles Relay 2 locally
# - Relay 2 is turned ON at boot
# - MQTT command topic supports external control of Relay 1, such as from an occupancy sensor
# - MQTT payload On turns Relay 1 ON and cancels any active timer
# - MQTT payload Off turns Relay 1 OFF and cancels any active timer
# - MQTT numeric payloads from 1 to 3600 turn Relay 1 ON for that many seconds
# - Any MQTT payload outside 1 to 3600 seconds is ignored
# - Relay 1 status is published to the local MQTT status topic as On or Off
# - This switch is used for:
# - Laundry Lights (1)
# - Laundry Power Enable (2)
#:########################################################################################:#
# MQTT COMMANDS:
# - Local command topic:
# - ${mqtt_local_command1_topic}
# - Accepted command payloads:
# - On
# - Off
# - 1 to 3600 seconds
# - Local status topic:
# - ${mqtt_local_status_topic}
# - Published status payloads:
# - On
# - Off
#:########################################################################################:#
# OFFLINE NOTES:
# a) Home Assistant offline (network and MQTT online):
# - Local buttons and local relays continue to work
# - MQTT control and MQTT timer commands continue to work if the MQTT broker is online
#
# b) MQTT offline (or HA/MQTT offline):
# - Local buttons and local relays continue to work
# - MQTT control, MQTT timer commands, and MQTT status publishing are unavailable
#
# c) Entire WiFi/Network offline:
# - Local buttons and local relays continue to work
# - MQTT control, MQTT timer commands, and MQTT status publishing are unavailable
# - Accurate time is not needed; SNTP is not required for operation
