Chris Sparks Sep 8, 2022
★★★★☆

Good app for viewing CAISO data and receiving push notifications for various alerts. However I have a somewhat often issue of the app failing to open. I'll click the icon and nothing happens, but in my app switcher I'll see a blank screen where the app should be. Closing the app doesn't fix the problem, but it will fix itself eventually if left alone and I'll be able to open the app again later.

This app is great! It shows a lot of interesting information about whats going on with current power consumption, max capacity, and estimated demand through out the day. The only this that can be annoying is during peak hours, probably when lots of people are using the app, the app seems unable to pull data and says to check your network connection. I assume the CA ISO API being used is being overwhelmed with connections.

Very informative!!! Especially if you're into data.

App bottom nav buttons covered by OS nav bar after upgrading to new phone...however...split screen mode allows access to the app nav buttons. Otherwise I enjoy the grid alerts and illustration of how energy source usage has changed over the years, particularly as battery storage has steadily increased.
