A system can include a first electrical device having a first controller that includes a first transceiver, where the first transceiver sends a first signal using a first communication protocol. The system can also include a second electrical device that includes a second controller having a second transceiver, where the second transceiver receives the first signal, measures a first strength of the first signal, generates a first table that includes the first strength and a first ID of the first electrical device, and sends a second signal using a second communication protocol. The user system can also include a gateway that receives the second signal, where the second signal includes the first strength and the first ID of the first electrical device. The gateway can also determine a first location of the first electrical device using the first strength and the first ID of the first electrical device.
