I've had at least one incident of a fail to charge event on a previous firmware revision and various other issues with lots of random resets and another instance where it was counting down to the wrong charging time. They had suggested I try using the cars charging timer, a terrible idea but ok. The problems remained I complained more and I have someone coming out on Friday to change the SD card. I hope this solves the problem, but I'm not counting on it.
At least I didn't pay $2,000 for this thing!
