Vero 4k vcgencmd missing

Help and Support Vero 4K / Vero 4K +
#1

Hi, I was trying to solve an overheating issue and found that:

osmc@osmc:~$ vcgencmd measure_temp
bash: vcgencmd: command not found

also:

osmc@osmc:~$ ls -lah /opt/vc/bin/
ls: cannot access ‘/opt/vc/bin/’: No such file or directory

vsgencmd is nowhere to be found
Can somebody, please, advise how to get it? And why it is missing?

#2

vcgencmd is a command only for the raspberry pi, it’s not available for the Vero devices.

Try this on Vero.

watch cat /sys/class/thermal/thermal_zone0/temp

#3

Thank you!
Could you, by any chance, advise how this could be implemented in a python script?

#4

The above is a shell command. You don’t need Python for this.

#5

Yes, i know. Wanted to use a python script to mail me in case of overheating.
I found this script, but it uses vcgencmd and would be nice if it can be adapted for vero 4k.

#6

Plug the following line into the python script, replacing the vcgencmd command.

#7

Keep in mind that the temperatures in that script will want adjusting.
The Vero will also already shut itself down if the temperature is too high.

#8

Yes, I thought high 75 degrees and critical over 95.
The unit was doing over 95 until I registered it and removed the screensaver.
Now it is idling at 52 degrees.
I just wanted to add an additional layer of security so I don’t start a fire inadvertently.
Unfortunately I am a stranger to python and cannot figure out how to adapt this script for vero.
A helping hand would be appreciated.

As @sam_nazarko wrote that safety is already build in. The device will reduce clock above 100c and shutdown at 120c

Thanks dillthedog! Seems to work, as I tried it with the first part of the script in a command prompt:
# coding=utf-8
import os
import smtplib
from email.mime.text import MIMEText

    critical = False
    high = 70
    too_high = 89

    # At First we have to get the current CPU-Temperature with this defined function
    def getCPUtemperature():
        res = os.popen('cat /sys/class/thermal/thermal_zone0/temp').readline()
        return(res.replace("temp=","").replace("'C\n",""))

    # Now we convert our value into a float number
    temp = float(getCPUtemperature())

print temp/1000

It spits out the temperature.
Now I have to debug the sendmail part as it doesn’t work for some reason.

Ok, thanks everybody for the help!

I have adapted the script and below is the working version if someone would like to use it.

# coding=utf-8
import os
import smtplib
from email.mime.text import MIMEText

critical = False
high = 70
too_high = 89

# At First we have to get the current CPU-Temperature with this defined function
def getCPUtemperature():
   res = os.popen('cat /sys/class/thermal/thermal_zone0/temp').readline()
   return(res.replace("temp=","").replace("'C\n",""))

# Now we convert our value into a float number
temp = float(getCPUtemperature())/1000

# Check if the temperature is above 70°C
if (temp > high):
   if temp > too_high:
       critical = True
       subject = "Critical warning! The temperature is: {,} shutting down!!".format(temp)
       body = "Critical warning! The actual temperature is: {} \n\n Shutting down the pi!".format(temp)
   else:
       subject = "Warning! The temperature is: {} ".format(temp)
       body = "Warning! The actual temperature is: {} ".format(temp)

   # Enter your smtp Server-Connection
   server = smtplib.SMTP('smtp.gmail.com', 25) # if your using gmail: smtp.gmail.com
   server.ehlo()
   server.starttls()
   server.ehlo
   # Login
   server.login("yourmail@gmail.com", "yourpass")
   
 
   msg = MIMEText(body)
    msg['Subject'] = subject
    msg['From'] = "Root@whateva.com"
    msg['To'] = "receivingmail@gmail.com"

    # Finally send the mail
    server.sendmail("receivingmail@gmail.com", "receivingmail@gmail.com", msg.as_string())
    server.quit()
    
    # Critical, shut down the pi
    if critical:
        os.popen('sudo halt')

# Don't print anything otherwise. 
# Cron will send you an email for any command that returns "any" output (so you would get another  email)
# else:
#   print "Everything is working fine!"

Now, I have no python knowledge, so I suppose inefficient techniques and useless parts might be present, but the script works, measures temperature and sends mails / stops the unit above the given thresholds.

A cron job to run it each N minutes is a way to use it once in place.
