Turn BOINC on or off depending on how warm the room is

README.md

Written by ChatGPT and me.

I also had to enable temperhum as a non-root user and set up a cron job to call this script every once in a while.

boinc_temperature_control.py

#!/usr/bin/env python3

import subprocess
import re
import datetime
import os

# Set the temperature threshold (in Celsius)
TEMP_THRESHOLD = 25

# Set the path to the BOINC data directory containing the gui_rpc_auth.cfg file
boinc_data_dir = "/var/lib/boinc-client"

# Get the current temperature from TemperHum
temperhum_output = subprocess.check_output("temper-poll -c", shell=True).decode("utf-8")
current_temperature = float(temperhum_output.strip())

# Set the absolute path to the log file
log_file = "/home/endolith/temperature/boinc_temperature_control.log"

# Change the working directory to the BOINC data directory
os.chdir(boinc_data_dir)

# Get project status
project_status_output = subprocess.check_output("boinccmd --get_project_status", shell=True).decode("utf-8")

# Extract project URLs and their "don't request more work" status
projects = re.findall(r'master URL: (.+?)\n.*?don\'t request more work: (\w+)', project_status_output, re.DOTALL)

# Check if the temperature is above the threshold
if current_temperature > TEMP_THRESHOLD:
    # Disable new tasks for all projects only if they are not already suspended
    for project_url, no_more_work in projects:
        if no_more_work == "no":
            subprocess.run(f"boinccmd --project {project_url} nomorework", shell=True)
            with open(log_file, "a") as log:
                log.write(f"{datetime.datetime.now()} - Temperature: {current_temperature}°C - BOINC tasks suspended for project {project_url}\n")
else:
    # Enable new tasks for all projects only if they are not already running

        if no_more_work == "yes":
            subprocess.run(f"boinccmd --project {project_url} allowmorework", shell=True)
