# MASTER BATHROOM HEATED TOWEL RAIL
# Controlled by a Sonoff Basic
#
# V1.0 2025-02-14 Initial Version
# 
# INSTRUCTIONS
# - It allows a heated towel rail device to work in a standalone operation
# - On startup, it will turn on for 2 hours then go into timer mode (this allows you to just turn it on to get some heat immediately)
# - The timer has a morning and evening time (but no weekday/weekend setting)
# - Default values are 5am-7am and 9pm-Midnight (as this suits our use case)
# - It uses SNTP for time setting (but obviously only if wifi & networking are working)
# - It will default to an internal timer if no wifi. To reset internal timer, reboot the device at 12pm (noon)
# - If on a network and there is a MQTT server, you can set the 4 on/off times via MQTT (See below commands)
# - You can set 4 modes ON/OFF/TIMER/STARTUP via MQTT
# - Any new timer times set via MQTT will be remembered though a reboot
# - On a reboot, the device will always turn on for the Startup Duration (STARTUP mode, default 2 hours)
# - TIMER mode will always be switched on after startup mode is complete
# - If you need it ON continuously with no MQTT, toggle power ON/OFF 4 times within 20 seconds (with ~2 secs in between to allow it to boot)
#
# MQTT Commands 
#     Values will be set in place on the update_interval time, not immediately
#     Use 00:00 in 24hr format for time setting.  Note there is no weekday/weekend setting
# mqtt_timer_topic/morning-on/06:00   : Time towel rail will go on
# mqtt_timer_topic/morning-off/08:00  : Time towel rail will go off
# mqtt_timer_topic/evening-on/09:00   : Time towel rail will go on
# mqtt_timer_topic/evening-off/00:00  : Time towel rail will go off
# mqtt_timer_topic/operation/ON       : Towel rail permanently on
# mqtt_timer_topic/operation/OFF      : Towel rail permanently off
# mqtt_timer_topic/operation/TIMER    : Towel rail will obey timer settings
# mqtt_timer_topic/operation/STARTUP  : Turn on for 2 hours then TIMER (also on startup)
