1-Wire Temperature Sensors

Temperature sensors such as the DS18B20 use the 1-Wire protocol. SolarThing can be configured to monitor these sensors.

Configuring your Raspberry Pi

The tutorial here: https://newbiely.com/tutorials/raspberry-pi/raspberry-pi-temperature-sensor provides a great walkthrough of the necessary steps to wire the sensor correctly and to enable the necessary drivers.

echo w1-gpio >> /etc/modules
echo w1-therm >> /etc/modules
# Note: if you don't have an external pull up resistor, you may replace w1-gpio with w1-gpio-pullup (not recommended)
# If /boot/firmware/confix.txt exists, run this
echo "dtoverlay=w1-gpio,gpiopin=4" | sudo tee -a /boot/firmware/config.txt
# If /boot/config.txt exists, run this instead
echo "dtoverlay=w1-gpio,gpiopin=4" | sudo tee -a /boot/config.txt
reboot

Editing base.json

You just have to add this json to your base.json:

{
  //...
  "request": [
    {
      "type": "w1-temperature",
      "directory": "/sys/bus/w1/devices/28-000006470bec",
      "data_id": 1
    }
  ]
}

You will have to change the 28-000006470bec to something else.

Restarts your application, and you should see that CPU Temperature packets are being uploaded.
