Onewire temperature sensor

  • Connect the sensor to the Onewire GPIO pin.
    • The following OneWire sensors are supported and are connected to the same GPIO (Note: please only use a data PIN resistor once. A DHT11 module already has one termination):
      • DS18B20

        DS18B20

      • DHT11
  • The pin can be set with the command
  • --onewire gpio 99  to set. 99...GPIO Pin #
    • All ESP32 and RAK modules are supported
      • Onewire Data-PIN with 4k7 resistor against 3.3V high voltage.
    • The sensor is connected to
      • --onewire on activated.
      • --onewire off deactivated.
    • The data can be transferred via serial console or APP with
      • --weather or
      • --wx
      • can be queried.
  • --wxdebug on provides additional information via serial console as an installation aid
  • DHT11
