A control method for a smart home system, and the smart home system, to solve the problem that existing smart home systems cannot match clothing and recommend a washing and care procedure. The control method includes: acquiring, by a household device, a current clothing image; sending the current clothing image to a server; acquiring, by the server, an ID account number of the household device which sends the current clothing image; determining, by the server, an identity of the household device which sends the current clothing image, according to the ID account number; determining a target requirement according to the identity; and selectively recommending a washing and care procedure or a clothing matching scheme on the basis of the target requirement and according to the current clothing image. Thus, a desired washing and care procedure can be recommended, and a reasonable clothing matching scheme can also be recommended.
