My model 3 long range is sitting in my garage. I charged it to 80% on Thursday night and unplugged it on Friday morning. It’s just been sitting since that time unplugged but undriven. It’s down to 51% on Tuesday morning. Down 30% in 4 days seems kind of bad. Sentry mode is on despite me having it set to not be on at home. Still seems like a lot of energy usage for a couple of low resolution cameras. Anyone else noticed this substantial energy usage when not in use?
Permanently “a few hundred watts” (or something around 300 W according to your calculation) sounds excessive for a passive surveillance system. That’s what a gaming PC uses while playing a somewhat demanding game, or a cyclist going uphill.
It’s not the surveillance system taking 300w to run.
To keep the car powered on enough that the system is working is going to take up most of that power anyway.
You’d have a similar problem with camp mode which keeps the car on, even with the AC and Sentry off.
In a perfect world if they could design the car so sentry gets powered separately that’d be cool, but sentry was an afterthought, and doing something like that with planning might still be completely impractical
