How to correctly set Class and conditions for ping?

Question

Python

I welcome everyone!
Tell me how, if the "else" condition is met, send a message to the user once, and not spam? And in case of reappearance of ping - send the message "Connection restored" to the user and return back to the beginning of the cycle.

Thanks in advance!

hostname = "*****" 
channel = '*****'
bot = telebot.TeleBot(<TOKEN>)


class RepeatTimer(Timer):
    def run(self):
        while not self.finished.wait(self.interval):
            self.function(*self.args, **self.kwargs)

def select():
    response = os.system('ping ' + hostname)
    if response == 0:
        print(hostname + ' пингуется')
        bot.send_message(channel , hostname + ' интернет есть')
    else:
        print(hostname + ' не пингуется')
        bot.send_message(channel , hostname + ' интернета нет')



if  __name__=='__main__':
    RepeatTimer(30, select).start()
    bot.polling(none_stop=True)

I tried with the help of Class
But there is not enough knowledge and experience for the correct setting.
Therefore I get an error:

type object 'stat' has no attribute 'status'

class stat():
    def contrl_stat(self):
        self.status = True

def check_ip_two(): 
    hostname = Config.ip
    if check_ip():
        if not stat.status:
            stat.status = True
            bot.send_message(channel, hostname + ' интернет есть')
    else:
        if (stat.status):
            stat.status = False
            bot.send_message(channel, hostname + ' интернет есть')
            
def check_ip():
    hostname = Config.ip
    response = os.system('ping ' + hostname)
    if response == 0:
        return True 
    else:
        return False
