  • Patent number: 10778461
    Abstract: In an appliance control system, a receiver receives, from a terminal device used by a first user, an instruction for remotely controlling an appliance installed in a home. A determiner determines whether a second user is present in a location in which an appliance-to-be-instructed is installed. When it is determined that the second user is not present in a location in which the appliance-to-be-instructed is installed, an appliance controller controls the appliance on the basis of the instruction. On the other hand, when it is determined that the second user is present in the location in which the appliance-to-be-instructed is installed, the appliance controller does not control the appliance.
