A system and method are described for accurately detecting a location of a wireless device. For example, one embodiment of a method comprises: collecting signal strength data indicating signal strength between a wireless device and a plurality of IoT devices and/or IoT hubs in a user's home; associating the signal strength data with locations in the user's home and storing the association in a location database; and determining a current location of the wireless device by comparing the signal strength data in the database with current signal strength data indicating current signal strength between the wireless device and the plurality of IoT devices and/or IoT hubs.
