The poller eventually realised the car wasn't charging at 05:50 this 
morning, after it was informed of an interruption to pilot signal.

Subsequently it seems to have followed changes of car state in a timely 
manner:

For the Leaf,
0 = Off
1 = On
2 = Drive
3 = Charging

So it might be that the only state transition it struggles with is the 
one where charging is terminated by OVMS itself.
