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).

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!

Alerts Broken

Want to be a good Californian but had to delete this app as the notification function is broken.

I received numerous maintenance alerts in the middle of the night (luckily I didn’t see them as I have “do not disturb” scheduled at night). I went to the app to turn off that function so that I only received flex alerts - but the badge number on the app didn’t go away, and the alerts kept coming. I force quit the app and restarted - still the same problem.

Developer Response ,

We are working on a fix for the erroneous multiple notifications tied to a single alert as well as how the alerts look after they’ve been viewed. While in the app, you can tap the “Alert” icon in the top right corner and go to the bottom of the page to “Alert settings” and turn off notifications for Alerts, warnings & emergencies, you will then only receive Flex Alert notifications. We apologize for the inconvenience, and hope you can use our app in the future. Thanks for notifying us.
