I installed the module on my 2016 Leaf with success, but I sometimes have the following issue when charging from my Wallbox at home:
Basically I connect the car, unlock the charger to start and after a few seconds the charge stops for no reason. By looking at OVMS logs, the session is stopped by the car with the message "Charge Stopped; Timer On". Useless to say, the timer is disabled in the car ( I even tried pressing the override button...).
I can't really confirm it, but it seems to happen only when it's cold outside (but not super cold, let's say around 1/0 C). If I bring the car to a charger on the road the charge starts without problems and goes on.
I've been banging my head about this for months... I cannot understand what the issue is. I even asked the Wallbox people but all they say it's that the session is stopped by the car, so they can't do anything.
