When you sign up you can decide to receive one or two forms of communication to let you know when the systems are doing their thing. One form is a daily summary and the other is each time the system provides balancing services.  After the system does a distance session you will receive a confirmation email indicating what was done and how many minutes each step took. Reports from some QAS members is that many can actually feel when the system is doing an energy balance and clearing...Seeing the emails allows you to correlate what you are seeing and the results specifically for you.
