Sensor ‐ ds18x Temperature Sensor - mkachline/guarduino GitHub Wiki
Guarduino supports reading multiple "ds18x" temperature sensors via the 1-Wire "DallasTemperature" protocol. These temperatures are then presented to HomeAssistant as "temperature" entities.

- Temperatures are reported in degrees Faranheight
- (2023 Nov) Testing is indicating only up to four ds18x sensors are supported.
- All temperatures are sent to MQTT with each Arduino "idle timeout" interval.
` #define ONE_WIRE_GPIO 8 // If you're using Dallas 1-wire "ds18x", define that pin here.
baseSensor allSensors[] = {
{reserved, ONE_WIRE_GPIO, -1}, // Pin 8
} `
