Hi Coady sorry this could be a long one sorry, I only came across this thread late last night and I can see your have a problem with the Zappi well I have look at the pictures from kia456 above and the screens in mine are the same so his bottom picture of the Zappi app on a phone I think.
You will see the Charging mode it is set to Eco so in that mode the car should start charging from the grid at around 1.3 or 1.4 kw about 3/4 minutes after it’s plugged in could be more kws if you have solar or a wind generator, Doesn’t matter, you will see this on the app and on the screen in the Zappi.
Now go to the Zappi app and the blue bar will be under manual which is where it should be at this point so now tap on schedule as in the bottom picture again Zappi will still continue to charge in Eco at 1.3 kw and the blue bar will move to underneath schedule
So now just to do a test lets say it mid day 12:00 noon it doesn’t really matter what time it s but I will use 12:00 for now, the car is plugged into the Zappi and Charing now lower down in the app page is the Boost timer settings and a grid will pop up with days on the left and hours across the top, at the bottom on the right hand side there is a + inside a circle, tap on that and 2 timers will pop up one for start on the left and one for Duration on the Right see picture.
So on the start timer set that to 30 mins or on hour from what ever your time is now and then set the duration for 15 or 30 minutes up to you and click OK .
The red box on the RHS of the graph is the currant time with duration set in blue.
00:45 minutes
Now Zappi will continue to charge at 1.3 until the time you have set is reach then it will go into Boost mode and the charge rate will increase to 7.2 KW and will continue like that until the duration time you set 15 or 30 minutes you set has past.
Ok test over now select Eco + Zappi will not pull anything from the grid until your set time then go back back to the timers and set what times you want, 4 hours if on Octopus Go then set the the start timer to 00:30 and the duration timer to 04:00 and chose which days you want this to happen That will give you 4 hours at 7.2 kws and then go back to Eco +. Pulling nothing from the grid.
I could show this to you in 5 minutes but to write it down with a few edits takes a while longer if you need anymore help just ask
