Housing Heater Plugin

Hello, can someone program me a plugin?
I built a heated printer housing. The temperature is measured via a DHT22 sensor, if it is too low it is heated for 30 seconds with a cooling-down period of 120 seconds, otherwise my holder will become soft. At the moment I am doing this with a Python script, here the source code:

import Adafruit_DHT
import time
import RPi.GPIO as GPIO
import sys

sensor = Adafruit_DHT.DHT22
GPIO.setmode(GPIO.BOARD)
GPIO.setup(40, GPIO.OUT)
ein=30
aus=120
aktiv="   "
last=0
tmp=int(sys.argv[1])
pin = 5
try:
  while True:
    humidity, temperature = Adafruit_DHT.read_retry(sensor, pin)
#    print(humidity, temperature)
    try:
      float(temperature)
    except TypeError:
#      print("JA")
      humidity=100
      temperature=100
    if (aktiv=="   "):
      if (last<time.time()-aus):
        if (temperature<tmp-2):
          GPIO.output(40, GPIO.HIGH)
          aktiv="EIN"
          last=time.time()
    else:
      if (temperature>tmp-2):
        GPIO.output(40, GPIO.LOW)
        aktiv="   "
        last=time.time()
      if (last<time.time()-ein):
        GPIO.output(40, GPIO.LOW)
        aktiv="   "
        last=time.time()
    print(aktiv, tmp, round(temperature,1), round(humidity,1))
    time.sleep(5)
except KeyboardInterrupt:
  GPIO.output(40, GPIO.LOW)

Hello @haschy!

You may have a look at this plugin: OctoPrint-Enclosure

Thanks for the tip.
Nice plugin, unfortunately it does not support my cool down phase, but by changing my python script a bit, it works fine.
Many thanks
