Hello Derek O, I have a MG4 Trophy, Long Range and use a dumb charger that was fitted yonks ago. I have had the same issues as all mentioned above. Last night I plugged in to start charging at 00.30hrs until 04.30 hrs. with OctopusGo tariff. Before I walk away from the car, I give it a minute or two for everything to click and clunk and watch the dashboard, it says 'scheduled charging' until it goes to sleep, LED's showing blue, all OK...nope as soon as I stepped away from the car it started charging! LED's turned to green. I unlocked the car using the remote and then locked it again and that seemed to reset the schedule charging as the LED's turned back to blue and this morning it had charged to expected 70 odd %. I've seen me set the time in the car only to find that the next time it has defaulted to 22.00 and 06.00 hrs. I also observed if you switch off schedule charging to charge away from base, either by the app or on the infotainment screen, that it defaults to the above and you have to reset your times. I used to have a Kona EV and you could switch off/on schedule charging and the times stayed set...although on occasions it would go rogue and start charging on its own!
Similar here, we have a ZS EV LR Gen2 and charge from an older type dumb wall box almost exclusively.
I have the head unit in the car set to match our off peak rates.
Before plugging in the car, the wall box displays a green standby light on the front cover.
Open the car with the fob and insert the type2 cable, then lock the car with the fob.
As soon as this happens, the wall box thuds.
Blue standby light switches from blue to green, suggesting that the car is pulling a charge.
In fact it is just conducting a hand shake with the car.
After a very short time, it has discovered that a delayed charge has been set.
Therefore the wall box thuds again and it has now returned to its standby state, displaying the blue light on the front cover once again.
Quick check through the drivers window and the info unit displays a graphic showing a charging cable is attached and states a delayed charge has been requested.
At the preset times I have set in the car, it will trigger the wall box to commence charging, when the requested start time has been reached.
I have also noticed the strange situation, that if you turn off scheduled charging in the head unit, when turned back on, it reverts to a factory default time and NOT my personally chosen delayed charging times.
I did get caught out by this once, I was playing around in the settings and turned off the delayed charging feature in error.
I then turned it back on, but failed to notice that it had reset back to the factory default times as a result.
By pure luck, I was passing my home energy meter at about 23.15 and noticed that the consumption light was RED !.
Indicating there was a large demand being consumed.
When I checked the wall box, it was charging the car - WHY ???.
My day rate is about four times more expensive than my off peak rate, so no charging gets done in this expensive time frame.
A quick check in the settings in the car the following morning, revealed the problem.
It’s an odd one aright and you do have to be aware of this issue, if you are regularly turning off he delayed charge function, as the default times may not match your personal off peak tariffs.
Also I have spotted a slide control in the head unit, that if selected, allows the car to continue charging IF the required SOC level has NOT been reached when the end delayed time has been reached.
I never use this function due to the higher cost implications.
