Reading of temperature from MAX31850K

Hardware

Hello,

How to read temperature from MAX31850K? Reading method does not work for MAX31850K the same as DS18b20. Thank you.

I used Appdaemon and python script:

mport appdaemon.plugins.hass.hassapi as hass
import os
import re
from glob import glob
import time
import datetime
from datetime import timedelta

class TEMPMAX31850K(hass.Hass):

    def initialize(self):
        interval_of_reading = 30
        start_time = self.datetime() + datetime.timedelta(seconds = 1)
        self.handle = self.run_every(self.read_and_set_temp, start_time, interval_of_reading)

    def read_and_set_temp(self, kwargs): 
        fireplace_first_floor_temperature = self.read_temp("3b-4cc80984ea83")
        fireplace_second_floor_temperature = self.read_temp("3b-2cc80984fc57")

        states_fireplace_first_floor = self.get_state("sensor.fireplace_first_floor", attribute='all')
        attributes_fireplace_first_floor = states_fireplace_first_floor['attributes']
        self.set_state("sensor.fireplace_first_floor", state = fireplace_first_floor_temperature, attributes = attributes_fireplace_first_floor)
        
        states_fireplace_second_floor = self.get_state("sensor.fireplace_second_floor", attribute='all')
        attributes_fireplace_second_floor = states_fireplace_second_floor['attributes']
        self.set_state("sensor.fireplace_second_floor",  state = fireplace_second_floor_temperature, attributes = attributes_fireplace_second_floor)

    # Function that reads and returns the raw content of 'w1_slave' file
    def read_temp_raw(self, deviceCode):
        w1DeviceFolder = '/sys/bus/w1/devices'
        f = open(w1DeviceFolder + '/' + deviceCode + '/w1_slave' , 'r')
        lines = f.readlines()
        f.close()
        return lines

    # Function that reads the temperature from raw file content
    def read_temp(self, deviceCode):
        # Read the raw temperature data
        lines = self.read_temp_raw(deviceCode)
        # Wait until the data is valid - end of the first line reads 'YES'
        while lines[0].strip()[-3:] != 'YES':
            time.sleep(0.2)
            lines = self.read_temp_raw(deviceCode)
        # Read the temperature, that is on the second line
        equals_pos = lines[1].find('t=')
        if equals_pos != -1:
            temp_string = lines[1][equals_pos+2:]
            # Convert the temperature number to Celsius
            temp_c = float(temp_string) / 1000.0
            # Return formatted sensor data, round to 1 decimal number
            return  round(temp_c, 1)
