Hardware

Connect the DS18B20 to the raspberry pi Raspi - DS18B20 3V3 -> VIN GND -> GND GPIO 4 -> DATA

Rember to add a 4K7ohm pull-up resistor between VIN and DATA on the sensor!

Installation

Enable i2c in raspi-config

Copy the files (as root!) report_temperature.service/report_temperature.timer from ./etc/systemd/system to your system /etc/systemd/system

Now tell systemd that you have added new files:
'systemctl daemon-reload'

save temperature_reporter.py to /home/pi/tempsense/.

Enable and start the timer:
'systemctl enable report_temperature.timer --now'

Store script at a differet location.

If you want the script to be stores elsewhere (not in /home/pi/tempsense/.) then you have to edit the file (as root!) /etc/systemd/system/report_temperature.service

Just change the line: ExecStart=/home/pi/tempsense/temperature_reporter.py

Configure the script before running.

in temperature_reporter.py

comfigure: ' INFLUX_IP = "" INFLUX_PORT = 8086 INFLUX_DB = "" INFLUX_USER = "" INFLUX_PASS = "" '

You can give the sensors costum names to be reoported by configuring the in the device names: device_names = {"28-000000000000":"Sensor_Name"}
