Well... TED recommended that I need an electrician to install the device on my circuit breaker. Once that was done, I had to figure out how to get the data to my laptop via Power Line Communication (PLC). As it turned out, it was harder than I thought since my router sat in the office - too noisy for the device to work. 50' of cabling later and almost 2 weeks later, I was able to see my energy usage in R/T. It was fun until I realized that I still didn't know which appliances were energy hogs... The TED connected to Google service so that I could monitor it at work. Again, I still don't know which appliances were on at a certain time.
Anyway, this HEM thing is for techno-geek. My wife wouldn't be able to use it. I think we need a lot more improvement for mass adoption. This could be something that UlluTek would investigate in the future.
