ESP-Now device for warning of the approach of Santa! This device has a Master which detects with PIR or a wire break to set a pin low--it is monitored when a TPL 5111 wakes the unit up. The solar charger keeps the device charged with a battery mounted on the roof. The receiver device (Slave) constantly monitors for the ESP-Now communication from the master and announces the arrival of St. Nick with a bright cascade of Led's.
