Hi all - I’m brand new to all of this and have a noob question… 
I have a tethered E7 unit. When it’s connected to my vehicle, does it do any sort of handshaking that passes, or is capable of passing, vehicle identification information back to the unit?
I’m asking as I’m unsure if charging is essentially, for want of a better term, open slather?
If so, I understand the potential for this could be somewhat restricted through a charging schedule.
The other reason I’m asking is I have a few friends with EV’s and wouldn’t mind them charging while visiting. However, for mainly safety (I live across a bridge** with a low barrier) but also privacy reasons, not other people.
To this end I thought the ability to have/create a whitelist of vehicles at some point in the future might be handy.
** not under 
Hi Steve.
Unfortunately at this stage the connection to a car doing AC charging is incredibly basic and the only thing we can really do is tell the car how much current it is allowed to use. And it’s a one-way signal so the car can’t say anything back!
There is a new standard that some cars are beginning to support which will change all this, but it’s not very widely adopted yet - a very small number of cars are just starting to appear in New Zealand. We will eventually add support for it, but right now it’s not a very high priority for us since there are still plenty of capabilities we want to add which will benefit everyone!

Thanks for the feedback Tom.
I suspected as much as far as protocols were concerned. With there not being many cars supporting a standard for this it’s quite understandable it’s a low priority. Good to know it’s on your radar though
HI - It appears that the charger (E 2) new install 2 days ago doesnt recognise the BYD Att0 3 and will not start charging at the scheduled time even though I have not set the predefined charge time in the car, The car info says that predefined charge time only works with slow (1.5KwH) chargers. I have to go to the car (at 23:00 hrs) to trip the charge cycle - seems like the car charge session computer is not compatible with e E2 software? Any solutons
Hi Jon.
This is an issue we have observed with the BYD Atto 3 and we are currently trialling a workaround which will avoid the problem. Essentially what happens is that the car goes to sleep and doesn’t recognise that it has been offered to charge when the schedule begins (or solar export target has been reached). We hope to have updated firmware deployed within the next few weeks.
I suspect the ‘only works with slow chargers’ is meant to apply to AC chargers vs. DC chargers, with the latter always starting immediately and in many cases charging idle fees while not being used in order to discourage drivers from plugging into them for long periods.
Regards,
Tom
