Shelly Plus 1

GPIO Pinout

PinFunction
GPIO0LED (Inverted)
GPIO4Switch input
GPIO19Future external sensors?
GPIO25Button (Inverted, Pull-up)
GPIO26Relay
GPIO32NTC
GPIO33Relay supply voltage sensor

The Shelly Plus 1 is based on the ESP32-U4WDH (Single core, 160MHz, 4MB embedded flash)

Please calibrate the NTC, the value below is just a rough estimate!
