Mine is never that choppy. I don’t have any devices that cause it.
Compress your timescale to match, 2hrs/screen or more. Of course it will depend upon what you are running but I don’t think your second graph will “smooth out” if you scale that way. Mine is super-choppy at that scale.
Here is 2 hours. You will see the last hour looks somewhat choppy but that’s actually the Kerrigan secondary 245 heater
I can’t replicate that choppiness at any scale
When you said you “just discovered these spikes”, did you mean:
- They have been happening for a (long) while and the new alert just pointed you to them.
Or - They are a new phenomenon ?
All large AC motors spike when their coils energize but your spikes look very large relative to my 4 ton basic AC unit (a 2000W spike associated with the On transition of 2700W steady state. Your spikes also seem to be associated a motor spinning down (power usage dips). Not sure why that would occurs but AC motors also generate power spikes like that if the loading on a motor suddenly increases.
Thank you Ryan, that info was very thorough and helpful. I’ll try to keep this thread updated as I learn more. Hopefully my experience will help others with similar questions.
I have 2, 3 ton AC units that work well but are quite old as far as ACs go. When these ACs power on I get a spike of about 5k per AC, which drops down to around 3600 watts while running. These recent spikes were much much higher and not something I had seen before. I’ll usually check Sense every few days to spot any patterns and see how my electrical load is for the day. On any given day my electricity will generally hit up to around 15k at peak and that’s at night with 2 ACs, 2 pool pumps, TV, and the dryer running. These spikes up to 20k are far from normal and they stuck out like a sore thumb. The strange thing is that they only happened over a period of ~ an hour and a half. These spikes have not returned since. It has also been much cooler here so I keep monitoring. I do appreciate everyone’s assistance and will keep updating as I learn or see more.
So it’s safe to assume that 15,000 watt spikes indicate a problem? 
Do you have Sense Labs activated?
In your case that could well reveal an issue and lead you to a fix.
