Having issues with my Heater randomly not turning on when the water temperature drops below the set pool temperature. It will sometimes function as what I would consider normal but overnight, more times than not, it turns off and does not turn on until mid morning when the temperature has dropped by 4 or 5 degrees.

I have updated the firmware to the latest 4.4.0 but not sure what else I can do.

There are a couple things that you can check:
1) Is there a schedule set in the app for the heater?
2) Is the main pump a variable speed pump that is on a schedule to be at low RPM during the night?
