# VERSIONS:
# v2.1 2026-02-25 Updated yaml to zorruno layout V1.1
# v2.0 2025-06-05 YAML Tidyups
# v1.0 2025-05-31 Initial Version
#:########################################################################################:#
# HARDWARE:
# - Zemismart KS-811 Triple push button (ESP8266)
# - Pinout/Schematic: https://community.home-assistant.io/t/zemismart-ks-811-working-with-esphome/
#:########################################################################################:#
# OPERATION NOTES:
# - Office 3-gang KS-811 (Triple) wall switch.
# - Button 1 toggles Relay 1 (Nighttime Lights) - only relay actually wired to a load.
# - Button 2 toggles Relay 2 (Daytime Lights) - virtual only (no physical load connected).
# - Button 3 toggles Relay 3 (Spare) - virtual only (no physical load connected).
# - GPIO16 does not support interrupts; polling is used for Button 1.
#:########################################################################################:#
# OFFLINE NOTES:
# a) Home Assistant OFFLINE, WiFi OK
# - Physical buttons still control relays locally.
# - MQTT is optional; device operates as a normal switch without HA.
#
# b) MQTT OFFLINE (or broker unreachable)
# - Physical buttons still control relays locally.
# - HA/API control (if available) still works, but no MQTT command/status.
#
# c) Entire WiFi/Network OFFLINE
# - Physical buttons still control relays locally.
# - Accurate time is NOT needed (SNTP not needed).
