# REPO:
# https://home.fox.co.nz/gitea/zorruno/zorruno-homeassistant/src/branch/master/esphome/esp-laundrylights.yaml
#:########################################################################################:#
# VERSIONS:
# 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 supports two actions:
#   - Single click toggles Relay 2 locally
#   - Hold for 2 seconds or more sends MQTT ON/OFF to the remote device
# - Relay 2 is turned ON at boot
# - Remote MQTT status is subscribed to and normalised to ON/OFF/TRUE/FALSE/1/0
# - If the remote state is unknown, a hold on Button 2 defaults to sending ON
# - This switch is used for:
#   - Laundry Lights (1)
#   - Laundry Power Enable (2)
#:########################################################################################:#
# MQTT COMMANDS:
# - Remote device command topic:
#   - ${mqtt_remote1_command_topic}
# - Remote device status topic:
#   - ${mqtt_remote1_status_topic}
# - Hold Button 2:
#   - Sends OFF if remote state is known and currently ON
#   - Sends ON otherwise
#:########################################################################################:#
# OFFLINE NOTES:
# a) Home Assistant offline (network and MQTT online):
#    - Local buttons and local relays continue to work
#    - Remote MQTT control/status for Button 2 hold still works if the MQTT broker is online
#
# b) MQTT offline (or HA/MQTT offline):
#    - Local buttons and local relays continue to work
#    - Button 2 single click still toggles Relay 2 locally
#    - Button 2 hold cannot control the remote MQTT device
#
# c) Entire WiFi/Network offline:
#    - Local buttons and local relays continue to work
#    - Remote MQTT control/status is unavailable
#    - Accurate time is not needed; SNTP is not required for operation
