This weekend we went away for 2 days camping - so car was parked with autopi connected. This morning the car doors could be unlocked manually only and the dash was dead. Couldn’t start the car.
I had to call the recovery service who briefly charged the 12v battery and the car came back to life.
Now I’m home I can take a look at the logs. The dash does show low aux voltage -
Which first I thought strange … but then looking at the logs I think this was recorded between autopi start and shutdown for critical level.
Is there a way to tell if the autopi caused the battery drain ?
