Temperature sensors
Both digital and analog sensors are supported, but only digital sensor input can support multiple sensors.
Use DS18B20 series digital temperature sensors. The GPIO pin for the sensor can be configured from the GPIO settings page. From v1.4, multiple sensors are supported and can be configured.
For more information on which sensors have been tested and how to correctly wire the sensors, see here:
If you are planning to connect more than one sensor, use Cat5 twisted pair for GND/DQ and run a separate wire for Vcc. To avoid frustrating problems with buggy sensors, you should use original sensors. More about original and couterfeit sensors here:
From v1.4, a single analog sensor is supported. GPIO pin is configured in the GPIO setting page. Currently, only TMP236 is supported.
