GPIO Pinout

Pin	Function
GPIO3	Button Input
GPIO4	BL0937 Ennergy Meter CF
GPIO5	HLW8012 Power Sensor CF1
GPIO12	HLW8012 Power Sensor SEL (Inverted)
GPIO13	Status LED (Inverted)
GPIO14	Relay

Configuration Notes

• This includes basic overcurrent protection in the form of an automation
• Voltage divider is configured as I found mine, but you will need to verify your own voltage/current/power calibration
