Running with -ct option results in 'Illegal sensor' and no temp readings

[brokkr]

Version: 0.6.2 OS: Ubuntu 16.04 Installed using pip

Using the -ct option to bypass a virtual device reading, I get no temperature readings and a note in the debug log saying the sensor is 'Illegal'.

Here's my sensors output:

acpitz-virtual-0
Adapter: Virtual device
temp1:        +27.8°C  (crit = +110.0°C)
temp2:        +29.8°C  (crit = +110.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +54.0°C  (high = +105.0°C, crit = +105.0°C)
Core 0:        +54.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:        +54.0°C  (high = +105.0°C, crit = +105.0°C)

s-tui defaults to the acpitaz-virtual-0 device. Seeing as this is always a steady 27.8 I figured it was not an actual reflection of the cpu temperature. Going on the --help instructions, I run s-tui in the following way.

 s-tui -ct coretemp,0

I have also tried coretemp-isa and coretemp,1 and coretemp,2. In the program I get 'Temperature N/A'. In the log (running with debug on), I get the following:

Explicitly setting the -ct option to acpitz result in the same thing just with acpitz in the log instead of coretemp.

Thank you for the detailed bug report. This is quite strange, coretemp should be the default.
To test the source of this, could you please run a python shell and the following code and give the result:

import psutil
psutil.sensors_temperatures()

[brokkr]

I ran it in both Python 2 and 3 as root. The result is the same:

>>> psutil.sensors_temperatures()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'sensors_temperatures'

>>> psutil.__version__
'3.4.2'

[amanusk]

Thanks. The problem is your psutil version. Temperature sensors were only added in a later version. Upgrading it should solve the problem

sudo pip install psutil --upgrade

I'll see how I can force a newer psutil version during the installation

Upgrading to 5.3.1 solved it, thanks :-)
