The page below shows how one might setup energy monotring but on my app it shows "Vacuums", not "Life" like they show in the faqs. So how does one really set this up? The app asked me this morning if I wanted to start monitoring energy usage but when I left the app to go calcuate the charge rate of my electric supplier that setup was gone with no way to access it again.
