So do you see these 2,052 watt peaks every 50 min in your main waveform?
4 min at 2,052W 26 times per day = 3.6 kWh/day so worth tracking down!
In the 2,000W realm electric radiant floor heat is a good candidate this time of year. @kevin1 has done a nice capture in the Device Library … although the regularity of your “Stove Top” may lends itself to something else. Try and rule out all the things with thermostats.
