Help with this Heat device!

So, need some help with this Heat device. New to this, so bear with me! It comes on after midnight, and looks like this:


Then again around 2am:

Then, when it comes on at 2:30am…

It stays like this (pulling around 800 or so watts) until 6am.

Is this a Tesla charging? I have a Model 3 that charges at night. Is it something related to our refrigerator? Any advice appreciated!

A Tesla Model 3 would be way more than that, even charging at 120V, unless you had the current dialed way down. Does Sense give you a crowdsourced set of possible choices ?
