I haven't been following all the renovation stuff, but how are you insulating those masonry exterior walls?

Have you heard about this device that attach to the inside of an electrical panel and can show you on a mobile device exactly how much power each and every item in your house is using? It works by detecting every device's unique electrical signature, so when you turn on the oven for example, a big circle will pop up on the mobile monitoring app that shows you much power that oven is using. It's a pretty neat looking device, and works on an amazingly simple principle.
