My heat pump has a timer setting. I can tell it when to start heating water or when to start AC. If your weekly schedule doesn’t vary widely it should be enough. I have it set up to heat the water during the nigh and heat up my apartment a little bit right before I get out of bed. I never needed anything more.
Getting up to turn on or off the aircon doesn’t allow for turning it on to make the house the right temperature by the time you get home
