Mystery spikes

I am noticing a regular spike of about 500-600w happening one minute apart for hours at a time, on a daily basis. Have tried flipping breakers on major appliances but could not pin down what’s causing it. Any guesses? I’ve attached a couple of screenshots. I would think it’s my hvac but when I flipped the breaker, the spikes kept happening in the live view (unless the view is on a delay?). Any help would be appreciated!

These seem to end up being Keurig or other coffee makers a lot of the time since they keep some water hot and ready.

Here’s a view of devices in the community device library between 500 and 600W

You might also want to look at ranges just above and below.

Do you have a coffee maker? Some of those pulse all day, even when “off”. Of my three Keurigs, one did this so we’ve stopped using it.

I just checked…you nailed it. in my case it’s not water heating, it’s a cup warming plate built into the machine. turned it on and saw the signature right away

interesting, another reply here mentioned the same thing, but I noted that it happens even when the delonghi espresso machine is off. how could it draw 600w when it’s not on? i’ll unplug and test.

Like so many modern l appliances, “off” doesn’t mean that portions of the device aren’t still drawing power. In the case of Keurig, they leave some heaters on all the time, kind of a standby mode.

One interesting thing about power monitoring is that you get to see how many of your devices have such parasitic draws…there are lots of them that do…electronics in particular.
