A method for controlling an apparatus, comprising: receiving from a home control device a notification message comprising an information item comprising address information on the home control device; receiving (202, 401) target object quality data from a home apparatus configured to process a target object, wherein the target object quality data is obtained by performing a quality measurement on the target object by the home apparatus, and the home apparatus comprises a home apparatus bound to the home control device, or a home apparatus located in a specified region where the home control device is; sending apparatus control prompt information to the home control device according to the address information on the home control device when determining that the target object quality data is less than a threshold, wherein the apparatus control prompt information is configured to prompt a user of the home control device to start the home apparatus belonging to the user for processing the target object; wherein the home apparatus for processing the target object is an air purifier for purifying air, or a water purifier for purifying water, wherein the information item of the notification message further comprises geographical location information on a house of the user of the home control device, and an apparatus type of a home apparatus in the house; wherein determining that the target object quality data is less than the threshold comprises: acquiring a plurality of target object quality data, in which the apparatus types of the home apparatuses corresponding to the plurality of target object quality data are identical, and the geographical location information on the houses corresponding to the home apparatuses indicates the houses are in a specified region; obtaining region quality data corresponding to the specified region according to the plurality of target object quality data; and determining that the region quality data is less than the threshold; wherein when determining that the target object quality data is less than the threshold, the method further comprises: sending an apparatus control instruction to the home apparatus, such that the home apparatus is controlled according to the apparatus control instruction; and sending a water quality reminder message to users in the region when the cloud server finds that the water quality is poor. receiving from a home control device a notification message comprising an information item comprising address information on the home control device;
