What do you think this is?


Heat 1, the suggestions are:
Oven 63%
Stove 32%
Dryer 1% (Already discovered)
Water heater 1% (Already discovered)
I tried the oven and the stove and got not response from heat 1.



Is that endlessly turning on every minute?



Any chance at 6:08pm, someone was trying to boil a pot of water? The activity resembles a stove top attempting to keep up the heat. Once the pot is boiling the on/off intervals lengthen in time.

Could be your water heaters second element. The top element is
used more but the bottom element is the same wattage and also
is used sometimes. They never come on at the same time as it
would overload the circuit.
I think it’s one of the elements, probably bottom.
Is your detected water heater 3800, 4500 or 5500?

My money is on 4500 or close to that!



Can you grab a power meter screencap? My first instinct is stovetop, but @samwooly1 might be onto something too.



a stovetop burner is unlikely to run at 4500. most ovens don’t
run that high because it would overload the circuit. The design
has to be setup so that if you turn the oven and all burners on
at the same time, it will not overload.
ovens are usually on a 50 amp breaker and that amounts to
40 useable amps (they are required to have 20% fore spikes).
That translates 2 9600 watts so I can’t see one element of the
range being 4500 with 4 to 5 additional elements to account for.



Where are you getting 4500 from? Looks to be drawing 1400W (or likely less if you account for assumed Always On/Other categories). In any case, some more screenshots would be helpful, especially power meter. The times in the initial screencap don’t match up (Heat 1 @ 6:08) and the power meter showing 6:11.



I don’t know Ryan@Sense. I had a brain shutdown.
sorry about that, can I delete my posts?
how embarrassing but thank you for pointing out my
mistake, I jus realized how I got mixed up. Was reading
a topic about a water heater before this one.
I’m getting old!
Ryan you are probably correct and its a stovetop burner

Is the cyclical on/off that 17W bump ?



What is the actual wattage consumption of the device in question? Look back at its history and see what it shows. It’ll help us narrow it down.



Since it was found on January 26 this is it’s pattern:

Jan 26
10:01pm found

Jan 28
12:10pm was on 4 times
12.17pm was on 2 times
12:20pm was on for 5 seconds
6:05pm was on 14 times
6:09pm was on 4 times
6:11pm was on 2 times

Jan 30
5:45pm was on 13 times
5:48pm was on for 3 seconds
5:49pm turned on
5:49pm turned off
5:50pm was on for 3 seconds
5:52pm was on for 5 seconds
6:08pm was on 15 times

Here is a screenshot of the last one (under device/heat1/power meter last 24h), it peaks at 1,503w:

This is my hot water heater, it’s pretty consistence with water being used and keeping the tank hot:

If I go to live feed and turn on one large burner on the stove it jumps on the graph by 1320w and by 752w for the small burner and they stay constant till I turn them off (5s later).

Let me know if there are more screenshots you would like



This is me turning the oven on and off

It looks like the water heater turned off at the sametime I turned the oven off



If this is my stove or oven how come it does not come on when I turn the device on? Is it possible that it’s just detecting the oven/stove maintaining temperature and not the startup/shut down?



Here’s my oven in action. Starts with longer preheat cycles, then shortens the duty cycle, plus modulates power as well. Each spike is about 5 seconds and each is about 1 minute apart.

I’ll try turning it on and see what happens. If I turn on my oven should heat 1 pop up right away? Or will it take a bit to recognize it?



It depends on what Sense recognized in the first place. It might only be picking up some part of the total signature, which can happen. If that’s the case, it should improve in time. I had similar confusion with my stove/oven and just left all the devices marked as a ‘guess’ for a while until things improved.



Could the 1500 watts actually be 3,000?
Your water heater appears to be picking up only one leg
as water heaters are 3800, 4500 or 5500 watts. If you
are sure the pic shown is your water heater then you
have a 4500 watt (the most common) and you can easily
verify by the label on the tank.
it just seems like, if your 240 water heater is only showing one
leg then maybe you have a 240 instead of 120 device that
is the culprit.



I think sense is confusing some of the oven signature with the hot water tank. I can’t be sure that the hot water is not actually on when the oven comes on or when the oven turns off. I guess a test would be turning the breaker off for the hot water tank then starting the oven. Below is a screenshot of lunch when I had the oven on:

This is the screenshot of the hot water tank over the same time as above:

This is me turning the oven on and screenshotting the live feed:

Thanks for your guys inputs I really appreciate it.



So does the bubble pop on and off with each bump? Or does the bubble come on and stay on?



Bubble goes on and off in sync with consumption.
