Great update!

Fantastic update! The app previously was marginally informative, but this update allows the user to access a great, great deal more data. The interface is both intuitive and efficient. Great job!

Very cool! One suggestion...

I think this app is so cool as an everyday energy nerd and day job campus energy manager who’s interested in system demand. One functionality I’d like to see is a graph where you can see today’s demand & net demand compared to this day last year, or the past week’s average, or both, or some other similar historical comparison. I like the “yesterdays renewables report” but it would be nice to have that data available more than just one day (ie through what I mentioned before).

Very useful app

I find the app very useful to alert me of flex alerts and other power issues. Glad I have it on my devices!
