Hi,
Does anyone know if or how I can use GPIO4 (“SW” contact) on a shelly1 plus as a ADC.
The shelly1 plus uses a ESP32-U4WDH chipset. According to the datasheets for this chip, GPIO4 can be used as an “ADC” (ADC2_CH0 GPIO4), but when I try to compile it in ESPHOME, I get error “ESP32 doesn’t support ADC on this pin”
