Has anyone tried charging the Ion with a "smart" charger?

I've recently got a ohme cable but the Ion doesn't like it much unless you set it to charge immediately.

Ideally I want to charge during Octopus cheap rate windows.

Not sure what you mean by “doesn’t like it”. If you plug an Ion into an EVSE that is unpowered then turn the power on to the EVSE later it will start charging automatically.

That should be enough for it to work properly with any EVSE with a built in timer.

I regularly charge my 2017 Ion with an Ohme 3-pin smart charger (three times a week on average) - which has been largely reliable for me, only minor issue is that the mileage requested in the app isn't very well calibrated - I decide on the mileage that I want and divide by 1.7 and then enter that number in the app and usually then get close to the mileage I want.
I'm on the Octopus Go tariff and the timing function for the cheap rate works fine for me (setting the charge schedule to finish by 4.30am).

I have tried the Ohme once on a 2012 C-Zero - and that had some issues - the app stated it charged overnight, but the car did not have any range added! Not sure if it was a connection problem between the Ohme and the cloud or not. I will try it again in the next week or two and see if it repeats. Is that a similar problem that you encountered?

When you plug it in the charger does a bit of charging and adds a couple of miles, then it powers down and waits for the scheduled time.

But it won't restart charging after that, says there is a problem charging.

If I go into the app and choose the max charging override in the first 30 seconds or so after first plugging in then all is fine.

Which profile are you using, there are a few imiev / Ion and model year profiles to choose from?

I need a full charge to get to Sheffield and back so always have it to add 100%

That also limits the time for fiddling because a failure means I can't get to work!!

Based on above advice, probably best to use s dumb granny cable and a 13A wall plug timer. Obviously not ideal but it will work.

I think that S Mandrake is suggestion the use of a wallmountef EVSE and running a timer to power the protocol controller on and off. That's only a small control current rather than the full 13A.

Hopefully I'm not too far off the mark????
