# FLY SPRAYER – Sinilink XY-WFUSB (ESP8266/ESP8285) – ESPHome
#
# V1.0 2025-05-30 Initial Version
#
# Device: Sinilink XY-WFUSB module https://www.aliexpress.com/item/1005005815472269.html
# GPIO: Tasmota template: Button=GPIO4, Relay=GPIO5, Led_i=GPIO14, LedLink=GPIO16
#
# Purpose:
# - Pulse a MOSFET/relay with 5 V to trigger a fly spray can at selectable intervals.
# - Sprayer has its own timers, but it fires whenever it is started up, which we utilise here.
# - Enforce a cooldown so it never double-fires too quickly (Sprayer has some memory)
# - Operation window select: Night only / Day only / 24 Hours / On / Off.
# - Randomize each interval by ± a percentage to avoid a perfectly regular pattern.
# - Red LED (GPIO14, inverted) pulses slowly when idle; goes solid ON during spray.
# - Green LED (GPIO16) as standard ESPHome status LED.
# - Has a resettable total spray count, and a daily spray count
# - has a countdown until next spray
