I wish. (viewing 12V battery voltage)

I wonder if you could bind it, hack it to MG S5 Australian?

The app whether android or IOS is generic. It's when you bind the car to the device using the scanned QR code on the infotainment screen as pointed out by @Ian Key, that the identity of the model is picked up and the features it has. It's looks Australia has a version that uses more of the data uploaded by the car to MG, whereas the UK and Norway only seem to display 4 parameters.

I think the details of the model of the car is preloaded into the head unit, when you scan the QR code, it brings over the info to the Ismart App on your phone.
When we upgraded from the ZS EV to the S5 the sales advisor unbound my phone from the ZS EV first, then reset the head unit to the factory settings, ready for the new owner.
Then he turned to my I phone ready to bind to the S5.
I asked him if I should delete the App on my phone, ready for the S5.
He said - No, when I scan the QR code on the S5 it will automatically pull the info over from the car, which it did successfully.
The image for the ZS EV had gone and the image of the S5 was on the front screen of the IPhone now !.
Of course the front page looked completely different to the previous front screen of the ZS EV.
So, the initial bind pulls the info into your phone.
For reasons only best know to MG, it appears that the number of health checks you can perform on the App for the S5 are different to the number of checks for the Australian market cars.
This is nothing new really, in Thailand they had the ability to turn on the heated seats on the ZS EV on the higher spec model, from the App, plus other features.
But not here in the U.K. .
Will these extra health check items be added If and when the Ismart App is updated ?.
Well it’s possible I suppose, but I would not advise holding your breath while waiting tbh.
Maybe just adding the feature to the App, is not be enough, without the software in the car being updated as well .
E.G. - If they added a feature into the App to now integrate / reveal say the 12V battery status, will the car recognise a request that has not been programmed to send to the App .

Interesting.

@Lovemyev, yes it's all making a bit more sense now how it works. Remains to be seen if it's an app update or car update that would bring more items into the vehicle status check, I suspect it'll be a software upgrade to the car that does it

Yes I agree, its not the end of the world but could be useful. What would be really useful would be a text alert if the 12 volt state of health starts to fall into a poor zone. Giving you a chance to get it sorted.

 

[EvTek23]

Would be a nice touch, but theoretically the 12V battery should never get into a low state. The intelligent charging of the 12V battery should take over. Maybe it should send an alarm on iSmart to say the intelligent charging mode has started. The proviso that this operates is that the HV is in a good SOC (50% is the figure talked about, but can't actually find it written anywhere)
Details of intelligent charging extract below on oage 24 of the manual

If you sit in the car with the power off, after about ten minutes it says it's switching off the infotainment to protect the 12v battery.

I couldn't understand that, as I assumed that the big battery would top it up.

Now I understand it less, as you say that that is exactly what happens...

Nice one, thanks.

I believe you did on the ZS EV models !.
It behaved in the same manner, if you had the car in standby mode, it would only allow the info unit ( listening to the radio while parked ) to continue for about 10 minutes.
Then the car would just suddenly shut down the 12 volt supply to the info / radio when the modules shut down completely.
I think the theory here is simply this, when the car is in standby mode, the 12 volt battery is receiving NO charge from the traction battery.
So to try and avoid you being left with a 12 volt flat battery it will automatically shut down the car down after about 10 mins.
I don’t believe the S5 is any different, with regards to this.
If am I sitting waiting to collect the grand children from school, I just leave the car in the ready mode.
Here the 12 volt battery WILL continue to receive a slow tricker charge and of course the modules stay fully active.

Seems the same on my S5. Thanks.

As you've found out it appears to only top up the 12V battery when the car is locked or in ready mode and apart from perhaps its different modules not speaking to each other I don't know why.

Maybe its to do with GDPR?
I cant remember how i paired my app and car..
