Configuration#
General#
In order to toggle different features and modes, please have a look
at the list of #define constants at the top of the sketch.
Weight scale#
Adjust SCALE_DOUT_PIN_X, SCALE_SCK_PIN_X, Taragewicht_X and Skalierung_X.
To find out about appropriate values for Taragewicht_X and Skalierung_X,
please use a weight scale adjustment sketch like
https://github.com/hiveeyes/arduino/tree/main/openhive/scale-adjust/HX711.
Temperature sensors#
Adjust DS18B20_PIN and the device addresses SensorX.
WiFi#
To configure WiFi SSID and credentials, please use the captive portal available on X.X.X.X when the device starts in AP mode.
GSM#
To configure GSM/GPRS connectivity, please adjust the
apn[], user[], pass[] and simPIN[] variables.
MQTT#
To configure MQTT telemetry, adjust the MQTT_BROKER, MQTT_PORT,
MQTT_USERNAME, MQTT_PASSWORD and MQTT_TOPIC variables.
Weather Underground#
To enable Weather Underground for getting nearby temperature and humidity
information, adjust WUG_API_KEY and WUG_STATION_ID.
