GPIO Pinout

Pin	Function
GPIO0	Push Button (HIGH = off, LOW = on)
GPIO12	Relay and its status LED
GPIO13	Blue LED (HIGH = off, LOW = on)
GPIO1	RX pin (for serial programming)
GPIO3	TX pin (for serial programming)

Basic Configuration

As the only controllable LED is the Blue LED, it is configured here to use the status_led light component, which will take over the LED in the event of a error/warning state, such as when WiFi is disrupted.

# the CSE7766 voltage/current and power sensor is connected to the ESP via the ESP's UART (the
# ESP8266 has only one)
#  - this precludes logging via serial, so disable that
#  - the CSE7766 emits data more frequently than desired (which in turn would be passed on by
#    esphome); use a filter to slow down updates
