You need a Queue and something listening on the queue

import queue
import threading
import requests
from bs4 import BeautifulSoup

def checkClient(q):
    while True:
        page = requests.get('http://192.168.1.25/8080')
        soup = BeautifulSoup(page.text, 'html.parser')
        value = soup.find('div', class_='valueDecibel')
        q.put(value)

q = queue.Queue()
t1 = threading.Thread(target=checkClient, name=checkClient, args=(q,))
t1.start()

while True:
    value = q.get()
    print(value)

The Queue is thread safe and allows to pass values back and forth. In your case they are only being sent from the thread to a receiver.
