Hmm, sounds very similar to REM sleep. Perhaps the Model S is dreaming of electric sheep?Definite pattern of ~9 hours of sleep followed by ~3 hours awake on a very regular basis .

Would a simpler voltage display that plugs into the "cigarette lighter" tell me the same thing?
But you could probably wire a data logger to a plug and get info without having to crack the frunk.It would if you stay by it and take a reading every so often. There's no recording function on those.
I have a 60 kWh and still have vampire losses.Basically, he only lost 20% of the charge in 27 days. Pretty good especially in the cold environment.
Yes, even with v5.8.7, my 60's vampire drain hasn't gotten much better. Still losing 7-8 miles at night when not plugged in at all. Temps are in the low 50s in my insulated garage.
That's unfortunate. Thought TM had sorted out the issue with the S60s. It appears they have made sleep mode more aggressive with the various iterations of 5.8 in terms of the sleep timer. Mine usually enters sleep immediately upon charge completion and doesn't take too long if I walk away from it during the day. I lose < 2 miles per 12 hours. Not sure what the issue is with the 60s.
@gg - Do you have the original gray 12 V? I don't remember when they switched over to the red one.
My 60 kWh Model S, on firmware v5.8.7 (1.49.84), still loses 7-8 miles of range when sitting idle overnight (for about 12-13 hours) when not plugged in at all. This is in an insulated garage where temperatures are in the 50s.
My car was produced in January 2013 and I'm concerned that this drain is because of the older (Exide?) 12V battery that may require more periodic topping off?! The car may be waking up more often than it needs to do as a result?!
I've read on the forums that many owners whose cars were produced in that timeframe had their original batteries replaced by Tesla to newer (C&D?) 12V batteries. Do I need a similar replacement?
Can you please let me know? I was at the Burlingame service center last week and this was not flagged at that time while several other service bulletins were applied...
Got an email reply from service at corp and then a call from the Burlingame service center. They pulled logs from the car and are fairly certain that it's indeed the 12V battery. Got an appointment next week to get it replaced.
Have to say, Tesla service has really stepped up to another level of late. Now, it's just a matter of having enough loaners.
I'm thinking mine sleeps while plugged in based on the amount of time it takes the dash and console to awaken when I open the door. The i-app also normally says that it is "Waking the car" most of the time it tries to connect. Just tried and it took over a minute and a half to wake up and another 15 sec to finish connecting. I'm losing less than 1 rated mile per day following a 12V replacement last Nov, so the S can now go several days before topping off.Wouldn't "sleep" only apply to an unplugged vehicle?

@mknox - Just curious as to what your rated mile loss per day is? Mine ranges between 3-5 rated miles/24 hours. I'm not exactly sure what that corresponds to in kWh/day, but my guess is between 0.9-1.5 kWh which is significantly lower than what you are seeing. I suppose if you take into account charging efficiency my numbers could go as high as 1.8 kWh or so.

I'll check my data logger this evening to see what I'm actually using from the wall since I have some historical data to compare it to.That's fantastic. I wonder why there is so much variability in sleep mode. I have a Sig just like you and lose significantly more than that in 24 hours. Service replaced my 12 V last month.
