Short version: Anyone got accurate information on when the 12V outlet is on/off on a Roadster 2.5? Can it be forced to stay on using a service code or something?
Long version: I've been using a dash cam for a while (more than a year). It works fine and runs from the 12V ("cigarette lighter") outlet. It now keeps resetting and/or forgetting the time and config. I think this is to do with the 12V outlet powering down when the car is locked or closed, and the camera battery dies before the 12V comes back. But it's not quite so simple - sometimes the camera resets, but sometimes it doesn't. It has definitely reset while the car was plugged in but not charging. It almost never resets when parked outside (locked, not plugged in) at work. In a recent service visit the car was indoors and I assume unlocked the whole time, and the camera ran constantly - I know this because it filled the 32 GB memory card with 2 days of footage which is about right for this camera. In my own garage under similar conditions it seems to forget its settings and power down a lot more often. I am currently recording the conditions each time I leave the car and trying to see if there's a pattern, because I had a gut feeling it was related to the SOC.
If I can't come up with a clear set of rules my next experiment will be to use an automated text message (via an email-to-SMS gateway) to wake the car up via OVMS every hour, or 15 mins, or whatever.
Thanks in advance,
Ian
