Well, I just saw a priming event around 7:50 am running at 1400 RPM. So, the 4:45 pm thing was a red herring.
Not that I've uncovered. The Android app and website are limited to really basic features. None of it is documented, and they never seem to update it. I still haven't figured out how to enable freeze protection after two years. It seems unlikely to me that the voltage is just dropping out and it's not trivial to capture an event like that.Does the pump have any type of diagnostics logs to show errors that have happened?
Maybe monitor the voltage and current to see if either is dropping out.
