A system can include a first electrical device having a first sensor device, where the first sensor device is configured to measure a first parameter used in operating the first electrical device, where the first sensor device is further configured to detect a first condition that is unrelated to operating the first electrical device, where the first condition is created by a trigger device controlled by a user, where the first sensor device, upon detecting the first condition, broadcasts a first communication that includes a first identification of the first sensor device. The system can also include a gateway communicably coupled to the first electrical device, where the gateway receives the first communication from the first electrical device, where the gateway assigns the first electrical device to a first group based on the first identification of the first sensor device.
