7200w motor

Sense found what it calls ‘motor1’; registers over 7000 W. My pool and spa pumps register far less. I don’t have any other large motors. Any ideas?

How long does the spike last ? How often does it come on ? Assuming this is the view from the Device Power Meter ?

Sense just Identified this the other day. I just popped up on the meter. Duration about one minute.

Well pump ? Sump pump ? Bladder pressure tank ? 7200W is a 1 HP motor starting up (or maybe a smaller one that is stuck).

Only have pool pump/ + spa pumps - all previously identified (they are 1-2 HP and each draw less than 3000 w).

The wave form doesn’t really look like a pump motor to me. I was just curious if anyone recognized the form. I will continue to monitor and try to ID.

I would look closely at how long it is on again… It has to be substantially less than 1 minute or we would see the minute marks on one or both sides at the bottom. Looks like 5-6 seconds or less unless your UI is having problems…

Yep. Took closer look - you are right - it was 5 seconds.
I will need to monitor and see when it comes on again.

You should also correlate the activity with the “actual” Mains waveforms shown in the Mains Power Meter. The Device meter is sometimes misleading.

The mains meter could indicate a 3kW-ish usage plateau (i.e. pump on) along with the startup spike. Seems like the device meter (which is the Sense native device recognition waveform) is missing the plateau … it’s just registering the startup spike.

Good luck !
I generally trust the physics-based calls of Sense. Very likely a motor. You might want to set an alert for that device when it turns on…That way you’ll get the alert coincident with the device having its short burst.
