Shelly Plus 0-10V

GPIO Pinout

Pin	Function
GPIO0	LED (Inverted)
GPIO4	Switch 1 input
GPIO18	Switch 2 input
GPIO25	Button (Inverted, Pull-up)
GPIO26	PWM (Inverted)
GPIO32	NTC

The Shelly Plus 0-10V is based on the ESP32-U4WDH (Single core, 160MHz, 4MB embedded flash).

The board is similar to the Shelly Plus 1 in pinout, but with an extra switch input and the PWM output instead of the relay.

Please Note: this device is a 0-10V SINKING controller for lightning (to be attached to a transformer, for example): don't expect to read 0-10V on the PWM output.

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