Abstract: Technologies for monitoring the performance of one or more electrical devices at one or more sites include a compute device. The compute device is to obtain data indicative of characteristics of resource usage by a monitored device. The data is usable to identify the monitored device and an operation of the monitored device. The compute device is further to determine, as a function of the identity of monitored device and the operation of the monitored device, an inference indicative of a condition of the monitored device, and send, to another compute device, a notification as a function of the determined inference. Other embodiments are also described and claimed.
