HVAC system power oscillations while warming car on shore power

So this morning was the first “cold ish” morning in Portland Oregon. So I had the car pre warm itself for me using the Tesla app to start it.

I have noticed this pattern before on my Sense monitor, but this one was such a clear graph that I figured I would post it.

It would seem that the Model 3 climate control is “seeking” some setpoint and oscillating as it keeps overshooting?

It feels like this is the kind of info some Engineer at Tesla might appreciate.

I saw this last night while plugged in with cooling required when I got into car to check USB cables. Input was 15 amps at 247 v. and it oscillated like your graph. Normal is about 5-6 amps at same temperature. Obviously a new bug.

FWIW, my car has done this ever since I got it July 3rd (as far as I know).
