Example of why someone would want to control it remotely: not infrequently, people pay less for energy used between x and y hours that are allocated to them specifically as a customer, or, also not uncommonly, people pay less for energy post-midnight prior to dawn when demand is lower, ergo, they can save a significant amount of money by doing their laundry at 3am. The above doesn't apply to me specifically, but I would like notifications when my washing is done and thus when I can put another load in. This can be done with energy metering or sensors that attach to washing machines or tumble dryers, but not done it yet myself, but would very much like to.
