Yeah, I used to not believe this but now after having the battery monitor and seeing how huge a change there is in sleeping behavior I just have to eliminate them. I liked Stats, but there is no ability to configure this behavior, and flogging the contactors constantly is not good for them even if they are rated for a million cycles. I feel like it got worse recently too. It seems the new algorithm is to wake up the car once an hour to make sure nothing is missed! Seems pretty crazy to me. Pretty sure there is a way to query the car without waking it up, but that is the way it goes.
It is not even enough to log out of the app! (AFAIK). You have to change the password as far as I can tell - Stats server is querying too I guess.

Below: Stats disabled - nearly 48 hours between ~2-hour wake up events! From November 9th at 2PM to Nov 13th at 8PM, I had 4 hours of idle time, and consumed about 4 rated miles (so one rated mile, 234Wh, per day).
So that tells me that idle uses about 230W (very approximate, would need longer interval and more data to know with more precision), assuming when idle it is charging the 12V (not always the case, but it is with these long intervals - it is the only reason the car wakes up in fact!!!).
The trigger threshold for wake-up is about 12.8V.
Now all I need is a current loop on the 12V cable and everything can be determined...but if the 12V charging current is 10A, then that would imply 240Wh per ~45h, or about 5.2W sleep power (quite high relative to an ICE, but consistent with what I have seen others quote). Need more info on the energy added during the 12V charging event to know for sure, though. The exact sleep mode current basically depends on how much energy in idle mode is going into the 12V, and how much of it is overhead (these estimates would imply about 100W of overhead, and 130W 12V charging energy).
