I came back from work today and attempted to charge my Leaf - nothing happened, the Blink screen showed "Not Charging".
I had no timers set up on the Blink.
I unplugged and plugged the Blink's charging cable into the Leaf a couple of times - no luck.
Even though I charge every day at that time, I turned off the timers on the Leaf - it did not help.
I tried "immediate" charging - it did not help.
Finally, tried resetting the breaker - at first nothing happened, after the Blink rebooted, I saw "Not Charging" like before. After a few minutes, all of a sudden I saw "Charging Pending", and 5 minutes later the charging started!
The only thing that has changed is that I see the Blink firmware was now upgraded to L2R.1.6A - I can't be 100% sure that this is what caused the charging headaches, but just thought I'd mention it here if anyone ran into the same problem.
