   My name is Adrian S. and I have very small feedback linked to this tutorial.
   50-raspberry-pi-linux-commands-and-utilities-youll-actually-use/

   A correction:
   dpkg –get-selections | grep XXX
   dpkg –get-selections

   A feedback:
   My CPU temperature is: temp=53.0’C
   My memory split between the CPU and GPU:
   arm=992M
   gpu=16M

   Thank you Terje!

   Hello Terje ,

   i have build my own version of yor temperature logger:
   https://www.circuits.dk/temperature-logger-running-on-raspberry-pi/
   works great so far with 1 to 4 sensors (snum=1 to snum=4)
   Now my problem is, i want to add sensor no 5, and ive edited the .py-script at line 21 to match that 5 sensor setup (snum=5), and ive edited line 92 to add the datapoint for the sensor

   from
   “fields”: {“temperature 1″:temp[0],”temperature 2″:temp[1],”temperature 3″:temp[2],”temperature 4”:temp[3]}

   to
   “fields”: {“temperature 1″:temp[0],”temperature 2″:temp[1],”temperature 3″:temp[2],”temperature 4″:temp[3],”temperature 5”:temp[4]}

   but it is not working, the output is:

   root@raspberrypi:/home/pi# python templogger.py -db=temp_logger_db -sn=test1
   (‘Session: ‘, ‘test1’)
   (‘Run No: ‘, ‘202004261449’)
   (‘DB name: ‘, ‘temp_logger_db’)

   (‘/sys/bus/w1/devices/28-00000bdeeb72/w1_slave’, 2, 33.5)
   (‘/sys/bus/w1/devices/28-00000be15ef1/w1_slave’, 3, 26.5)
   Traceback (most recent call last):
   File “templogger.py”, line 110, in
   datapoints=get_data_points()
   File “templogger.py”, line 81, in get_data_points
   temp[sensors] = read_temp(device_file)
   IndexError: list assignment index out of range

   the sensors are found:
   root@raspberrypi:/home/pi# ls /sys/bus/w1/devices
   28-00000bded388 28-00000bdeeb72 28-00000bdf14a5 28-00000be12694 28-00000be15ef1 w1_bus_master1

   can you help me, what am i missing to get the script and database working correctly?

   Thanks and greetings from germany

   can anyone explain the pyhton code part7. Temperature logger python code .It seems that there are no relevant explanations of the code..Ex:
   And the setup for influx database are not up to date??
   EX: from code??

   # add more sensor variables here based on your setup

   temp = [‘sensor code’, ‘tttttttttt’, ‘ddddddddddd’, ‘ssssssssss’]
   base_dir = ‘/ sys / bus / w1 / devices /’

   device_folders = glob.glob (base_dir + ’28 * ‘)

   snum = 4 #Number of connected temperature sensors

   # Set required InfluxDB parameters.
   # (this could be added to the program args instead of being hard coded …)
   host = “localhost” #Could also use local ip address like “192.168.1.136”
   port = 8086
   user = “root”
   password = “root”
