I am planning a cost effective automation for our remodeled home. I want to be able to control my refrigerator,smoke alarm,security cameras,door locks,lights,garage doors and air conditioner but the problem is each of them has a different app and recently we got this Go-Clair Premium Air Purifiers with e2f technology. which doesn't have app control. Since we have one for the air conditioner I felt it would be nice to have one for our room air purifier as well. Is there any way to control parameters of devices like this which don't have inherent automation perhaps by connecting it to a switch device?Also is there any universal android app which can integrate all the app controls in one particular place? I don't want to spend a lot on an expensive hub.
