We have a new MG4 Trophy and perhaps unwisely went for the EO Mini Pro 3 charger as it compatible with Hive and we have loads of gadgets on Hive.
Having no end of charging issues.
The charger keeps going into fault after charging.
The car won’t accept a charge unless we tell it to on the MG4 app.

So:
How do we get the MG4 to accept a charge once the charger is ready and all cables are connected?

Has anyone else got the EO Mini Pro 3?
I’m about to start formal complaints with Hive around the fact it is so temperamental.
Had the charger since Thursday (so day 4) and it has gone into fault status on every day so far.

I'm afraid I can't help but would be interested in hearing how you get on and welcome to the wacky world of MG 🤓
 
Have you got schedules set on the car and the charge point? Apparently it has to be only one to work or it ends up with a conflict and won't.
 
If you have a powerline adaptor fitted, they can cause problems. I have an eo mini 2 but have not got hive (a step too far for me) it works well. I have the time set in the eo app and not in the car.

Thank you for replying. I’m not sure what a power line adaptor is? A quick google shows they’re 3 pin plug adaptors to extend your wifi? Our EO mini is hardwired directly into the meter with its own mini fuse board.
I wonder if I can connect my hive EO mini pro 3 to the EO app? It is branded with Hive on the front of the box…

Thank you for replying. No schedules on each that I know of.
A good tip to maybe only try and schedule using the car when we get that far. Just trying to get the charger to not fault is my first goal 🤣🤦‍♂️

Hi there. Are you able to tell me if you managed to solve this issue? Same as yourself, I have the Hive EO Mini Pro & a newly delivered MG4 Trophy. I am having exactly the same issues as yourself but am yet to even have a successful charge. I've tried setting a schedule on the car, just plugging it in in the hope it will just start charging, but I keep having 'connection issues'. I've managed to charge to car with no issues at my local charge point, and it works as you'd expect - so the issue is definatly with the home charger 😖😡
 
Have you had any progress here? I have similar/same issue(s). We have the eo mini pro 3 and mg 4se. Generally the blue (ready) light is on the charger. But if I check the app it will often say can't reach server. I've been reliably (?) informed by hive customer service it's definitely not a problem at their end. But I live in what I consider to be a good reception area so don't think it's connectivity as such. When I plug in the cable generally one of two things will happen:

1) car and charger don't see each other, cable doesn't lock in the charger, further supporting idea that the charger isn't actually awake. Light stays on blue. Still can't reach server on app. Hard reset (flipping fuse) will usually then bring it back online (yellow light) and it will generally then charge on the Freecharge schedule overnight.

2) the blue light will change to yellow light and it may or may not then connect to server on the app and charge overnight, but still can't guarantee.

Hive have made it very clear it's got to be my charger, my connectivity and thus my problem (and my fault for not checking, although how you can check something you don't own I don't know, and I believe we're in a reasonably good reception area).

In short, I wonder if it's actually a faulty charger, which (worryingly) doesn't seem that uncommon.

And don't get me started on the freecharge system itself (doesn't seem to be registering any of the charges as freecharge, despite them all being freecharge, so currently disputing the refunds.
 
We’ve managed to resolve our issues.

Our problem was the voltage coming into our house was / is too high.

The error for our EOminiPro was ‘ground error’ which means too many volts.

The electricity network tried monitored it for a week and agreed it was too high but said it is unlikely to be fixed

We’ve had to instal a voltage optimiser to reduce our voltage.

Since then it has been working well. Just make sure the car does not have scheduling turned on for charging as I must be honest often we need to use the app or the car to start the charging.
Occasionally the Hive app says the charger is offline but it has not gone into error over the past two months.

If Hive are saying it’s the charger they should be replacing it under warranty. Ask to be put through to that team who will organise it.
I found them to be very helpful as they sent screenshots of when it was connected and charging the records of voltages etc.

We can have the issue of the car not seeing the cable but the charger does go green

We installed before free charge unfortunately 😞 I asked to be put in it due to their issues but that was ignored!!!
 
How did you know the error was to do with voltage? And hive aren't saying it's the charger (yet) -they're saying if it's the gprs then that's my fault for not checking beforehand
 
As I said in the post the error was ‘ground failure’ and that means high voltage.
The Hive EV warranty team can look at the status of the charger and tell you the error message.
When I got that error message I also asked EO themselves what that error was.
Not sure how you can check if the hive will be able to connect to a mobile network when we don’t know what mobile network they are using. That’s a pretty poor excuse.

My bolding. You need to challenge your DNO about this!

In my early days with my home EVSE (Rolec) I several times experienced it going off-line and shutting down. After several return visits, my installer was able to verify that over-voltage was causing the issue.

Each DNO is mandated to supply your electricity within the range of 216 to 253 volts. Mine was measured as high as 259 volts, thus triggering the EVSE shutdown. The installer contacted the DNO who came and tested the supply (they installed a logger which monitored our incoming voltage for 7 days; it was their monitor which measured the 259 volts, or higher.) They therefore agreed that they (the DNO) must reduce this. They did so by making adjustments at the local electricity sub-station and I have not experienced these EVSE failures since.

Thankfully, all the above occurred before my car arrived so home charging has, for me, never presented any problems, unless caused by human (read: my) error.

The fact that you have had to install a voltage optimiser is, in my opinion, outrageous when it is the responsibility of your DNO to not exceed their legal supply voltage range.
