Domoticz

With help of google I made a Python scrip for sending my server CPU temperature running PROXMOX VM to a virtual sensor
The temperature is updated in the file : /sys/class/thermal/thermal_zone0/temp
Only reading the first 2 digits on the first line.
Send this value to a virtual sensor in Domoticz every 5 minutes.

Note: This script has to run on the Proxmox server itself !! Not on the OS Domoticz runs on !!!!!

Normal Domoticz motherboard sensor gateway is not working in Proxmox environment?

Thats right. Domoticz runs on Ubuntu in a Proxmox VM.
Domoticz can't access the server sensors.
With this script running on the proxmox server itself it sends the CPU temperature to the IP address od Domoticz.
This way I'm able to monitor and get an alarm on Telegram when my CPU temperature is getting to high (summer time).

Hi.

Works fine!!
Do I need to create a crontab for this python file?
How can I check that this process is running and restart it if that would be necessary?

Kind regards.

Hi.

The script runs once and then it stops.. The delay for restarting the query is not working.

So I've altered the script and just remarked the timer and added "quit()". So that the script stops and the process is deleted.

I've added a crontab line so that the script runs every xx minutes (choice).
Crontab:
*/5 * * * * python3 /root/temp2domoticz.py

Script:
## start script ##
import os
import re
import requests
import time
import sys

while True:

file = open('/sys/class/thermal/thermal_zone1/temp', 'r')

first_line = file.readline(2).strip()

# Close the file
file.close()

domoticzserver = "10.10.3.2:9080"
idx_temp = "4856" # Put youre own IDX here of the virtual sensor

val_temp = first_line


res = requests.get(
"http://"
+ domoticzserver
+ "/json.htm?type=command&param=udevice&idx="
+ idx_temp
+ "&nvalue=0&svalue="
+ val_temp
)
#time.sleep(5) # wait 5 seconds
quit()
## end script ##

@sloeber my script keeps running I started the script ending with & like: python3 /home/domoticz/domoticzCPU.py &
Added this to contrab for auto startup.

Nice to see it works for you
