Error on running pihealth.py about pi-health-dashboard HOT 8 OPEN

When you run the command:

vcgencmd measure_temp

do you get a response?

from pi-health-dashboard.

VCHI initialization failed

from pi-health-dashboard.

Looks like other people have had this issue with vcgencmd in the past (e.g. https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=50262). You can try some of the solutions other people have found or you can simply comment out the python lines that are grabbing CPU temperature (lines 27-32).

sudo vcgencmd measure_temp gives the correct result. Permissions on /dev/vchiq are correct. I will look for another solution and send feedback.

Have you tried running the Python script with sudo?

sudo python pihealth.py

from pi-health-dashboard.

That’s what i do now and that works. It’s a system that is exposed to the
internet, so having a script running as root is not my preference, but
anyway, now it works.

Traceback (most recent call last): File "pihealth.py", line 80, in <module> main() File "pihealth.py", line 27, in main cpu_temperature = get_cpu_temperature() File "pihealth.py", line 21, in get_cpu_temperature return float(output[output.index('=') + 1:output.rindex("'")]) TypeError: Type str doesn't support the buffer API

Error i got when trying to run the pihealth.py file

from pi-health-dashboard.

vcgencmd measure_temp works OK.
As suggested by @jrbail01 above, the workaround is to comment out the CPU temp lines.
What's the proper fix for this, please, so I get CPU temp on I.S?

Here's a working, proper fix:

Line 21

#    return float(output[output.index('=') + 1:output.rindex("'")])
     return float(output[output.index(ord('=')) + 1:output.rindex(ord("'"))])
