Hi All, I have just had a bit of a painful experience with my 12V being drained (twice). I'm guessing it's related to OVMS, but also something seems to have happened as it was running file for a week! For some reason, the 12V battery graphs aren't working in the (android) App.. which means I'm not quite sure of the timelines, however it was most likely overnight. This morning my 12V was severely depleted (like 6v!). (Oh, it could be because I don't have the app running in the background). I'm assuming it's likely not to be the direct drain of the device itself, but maybe something it is querying on the CAN busses or something that is then causing a consequential power drain? I got road-side assist out and they got me going, but then 20mins later it was flat again! (I did see an alert in the APP and so was quick to go out, but was unsuccessful in getting the car going before it died!). I'm going to unplug it and see if that stops the card from dying. Also, I might leave the car on for a bit longer.. but still I have concerns! Also I haven't started using 'write' commands yet. Any ideas? //.ichael
