Please fix the charts. Bring back the half-hour charts. When the 30 minutes safety limit is reached, sometimes it does not reset when it should. It skips 30 minutes window, and then resets. I have to manually disable the API, re-enable it, and now it starts to pay again until it breaks.
Edit: I don't know how the safety limits work behind the scenes, but maybe some timer is broken or there is conflict with the old way you did the limits before the change.
