Question ac remote

[remynajm]

Hello, I have a small business that is kind of automated to be functioning without employees. I need my airconditions to be on everyday from 7 am to 10pm so what I am doing in this case is using the smart app of my air condition to schedule the on and off of the ac but the problem is these apps are not so reliable dues to the internet outages here in my country. Is there any product that kind of works as a timer but doesn't require wifi. All i need is like a smart remote that has a clock in it that know when to send a signal to the ac to turn on and when to turn off. Any help would be appreciated...
