Fast is the dumb charger mode which is what your after. Plug in and charge. Eco and eco+ are for solar use. Once the car is full it should release the cable.
The car has to release the plug and should do if the charging is stopped on the zappi / zappi app/ Car or car app. I assume it can be stopped by the car or the cars app.?
If you do get a tou tariff then Fast and using the cars timer will work.

 

Isn’t the eco+ mode also required if you use the timers on the Zappi?

 

You should see on the front of the Zappi if it putting power into the car as a kW figure and how much has been added.

 

I leave mine in eco+ with a timer set on the myenergi app for a 4 hr charge at night. No timers set in the car. Works perfectly, just plug in and leave.

 

Davel82 - Oh so I could just leave the Zappi in Eco+ and setup a timer for 4 hours? I guess this is instead of just plugging it in to charge to 100% all the time? Is it not good to keep charging to full then?

 

There are a few reasons to use timers, one could be so that you can use solar charging through the day and also get full speed charging during a cheaper off-peak period over night. The other might be due to your supply capacity - if you have a limited incoming supply you might want to charge over night when there is less load.

I use the Octopus Go tariff, so stay in Eco+ mode and use Zappi timers to “boost” from 00:30-04:30 every night.

 

Daft question of the day. Presumably, even though you set the timers for 4 hours, the car will still obey the maximum charge level set in the car? i.e. 80%
