If the car is unlocked, opening the barn door will not fire up the Pivi.
If the car is locked, you can open the barn door by pressing the boot button on the key (or activity key) again, this will not fire up the Pivi. Otherwise, just place a carabiner in the locking mechanism, double lock the vehicle and leave your barn door open.
Car will instantly go to sleep.
Opening any of the 4 side doors will fire up the Pivi for about 2 minutes each time.
Since my last post here, I disabled keyless entry which saves me from wrapping the key. Whether it be camping or at home, keyless entry was my biggest battery drain issue. Below are other settings that also help when camping beside or on the vehicle:
- disable interior lights
- disable Homelights (headlight delay)
- crack a side door open
- carabiner in barn door

I've left the car (double locked, no trickle charge) for two months and not had a low battery warning or any problem restarting the vehicle on return.

 

It's side doors that fire up PIVI.
Disable approach locking/unlocking too...

 

Thanks VillaDazzler and TeddyG, appreciate the insights.
( I just ordered the rear door factory latch 'd' ring to mate to printed plastic bases, likely will do the same for the rear pass. door's too. )

 

I've wondered why some computer program in Pivi doesn't just allow owners to activate a "save battery" mode, where the car won't hit the battery every time a door is opened. For example, why can't the car "wake" if the driver's door is opened, but not wake at all if another door is opened, or if you leave a door opened? Isn't it just a matter of writing a program to allow the owner to silo the "wake" mode to happen only if - for example - the driver door opens? IDK, but this seems like something an OTA update can hopefully fix.

 

So it begs the question - where is an appropriate place to contact/email to try to get a few of these suggestions in front of an empowered team at JLR's Defender coding/UX group?

Agree - re / above coding should be simple to offer 'drivers side only wake' state. I'm not sure this is currently possible via IID Gap Tool's preference file editing?

 

if you leave door opened it won't fire pivi after it goes to sleep. Just nudge it a little so it catches on latch.
I'm camping often, don't really have a big issue with battery draining. The key is opening gate doesn't fire up PIVI, leaving any door not fully locked also helps.
Do not use approach lock/unlock (it's useless anyway).

 

Does anybody know what is the CCF setting for disabling Homelights? (Follow me home lights)

 

Is the Pivi system in Defender able to tell you the current battery charge/remaining life? I found where I can check the tire pressure - great! Still looking for things like oil/coolant levels, and the charge on the battery? Those all seem like things Pivi knows and monitors, so can I see that stuff on Pivi and make sure Defender is ready for a long trip? Thanks.

 

None of those features are available in either the gauge cluster or the infotainment screen. The only telemetry JLR tells is the tire pressure, and some off-road telemetry like elevation, coordinates and slope angles.

 

there's a screen on the dash that has only a pic of the Defender, and another screen that has a clock. These seem like useless scroll visuals. You know that scroll area? ... I"m thinking JLR put those in to make space for planned upgrades - now they have the area already there, they just need to write a program to over-write the pic of a Defender that's now there. I get that JLR has lots of issues to go through, but at some point, one of the OTA updates may bring those features to my Defender. Given how critical the battery is, I have to imagine that one is high up on their "to do" list... I can hope!
