I have been unable to identify a “pump” that was detected several weeks ago.
The power meter for the past 24 hours shows it cycling on and off rapidly about 20 times (sorry but the system restricted me to only one image).
Here is the waveform:
I have determined this is not the sump pump, the condensate pump, the washing machine, or the (gas) hot water heater exhaust fan but I have been unable to figure it out. Notice that it runs only for a few seconds, so it is difficult to track it down after I receive the notification.
I will appreciate any ideas you may have on what this is or how I can better identify it.
