I on the other hand do want connected appliances because this will allow automation to run them when e.g. there is a lot of electricity from the sun or wind, which is the future of electricity grids. A dishwasher is perfect for this because it basically runs daily, but most of the time you don't really need it to run at a very precise time. As for expensive control boards for the old broken down machines, I found someone on eBay that repaired them and fixed my washing machine for 40. The control board is just a plastic box with cables running to it. Disconnect, take it out, mail it, and install it once you get it back. Fixed.
