When we first got our Zoe they installed the wrong breaker for the charger so it would trip after a while. I would reset the breaker and it would work again.

Several times the breaker would trip in the evening but I wouldn't reset it until the morning, hours later, but it would start charging again without problem. How did it do this?
My breaker does the same but only when it’s cold outside. What did you replace it with @philhimsworth?

Type D, I should imagine.

The Chargemaster guy had only installed a 20A breaker for a 32A charger; I presume those are what they use for 16A chargers so I guess the guy just pulled the wrong one out of his van.

It was swapped for a 40A type C I think. It has worked fine since then, anyway...

40A type C works for many people, by all accounts. Changing it to 40A type D works for others.

I get the feeling that people generally refer to the "planner" on this forum. I would bet that the "start at" function doesn't require any connected services. I have no way of testing though. What we need is somebody with no connected services to test it out for us...
Never used the scheduler but almost always use the “start at” function. Occasionally I get up in the morning to find no charge has taken place. Usually I can manually start a charge from ZE Services but again, occasionally even that fails. It happened a couple of days ago and I got the text message:-

Charge of vehicle couldn't start.
Vehicle out of reach or already in charge.
The Renault Team

This suggests to me that the “start at” function does indeed need a connected services signal either at the time of initiation and/or at charge start time. Any thoughts anyone?

Incidentally I have “limited” Z.E. Services functionality as I can’t initiate a manual charge from my phone app but can from the website on my laptop. I used a workaround in a thread on here somewhere to keep at least some functionality without renewing my subscription :whistle: which only lasted 1 year . Very miserly of Renault IMO.

That's curious, since they both use the same API and talk to Renault's servers in exactly the same way... can you from the website via your phone, I wonder? (That's practically the same experience as the app, only without the irritating splash screen...)

I just use the website on my phone rather than the app as it's quicker to start up!

It does have the bizarre difference that you don't need to confirm anything, stuff just happens anyway; if you say yes it just complains that you've already done it...

Website via phone also works. Never bothered to try before as expected to have to login with password which I can’t remember whereas on laptop I have a saved favourite that goes straight in with one click. Now I know I can do the same via the phone as well so thanks. :)

Connection to Renault server is required for both Calendar and Begin charging at options. When our TMS was faulty, charged timing didn’t work.

Check you are connected. For both our Zoe’s I’ve needed to perform a TMS reset via Fuse F34, so it reconnects to Z.E. Servers.

No need to pay for extra years access to Z.E. Services for continued times charging either. Once the services run out, log back into Z.E. services on the app or website and switch Driving Mode back on (in the section where the VIN is). It can take 24 hours to re-connect to the car, but it all carries on working from then. Our first Zoe worked for over a year after our subscription ran out.

That's interesting... even when our TMS has crashed or whatever it does so the app doesn't update and it won't send text messages about charging, the "start at" timer has still worked for us! It seemed to be only when there was a server problem or something that it stopped working.

I’ve never had a text saying the car is charging or it’s stopped charging but did get about 5 one evening telling me the car had low charge.

(Is plugged it in and scheduled it to start at 1am)

On my previous Zoe R240 when the services expired the timed charging still worked in car but the calendar charging was not selectable in car.
Connection to the server was still required for timed charge.

I went to our local electrical factors to ask about them; when I mentioned type D the guy was gobsmacked that anyone would ever use one outside of industrial equipment...
I know, you're right. It's a somewhat contentious issue relating to the Zoe's fussiness. A Type D breaker is the workaround officially adopted by charging point manufacturers such as Rolec, whose charging points are rather unique in that they have a breaker built in (which is routinely switched from Type B to D, for installs for Zoes).

Re: the My ZE app. Has anyone got any experience of this app?! I had a Leaf before my Zoe, and used the Nissan charging app to remotely check the battery status, and charging % whilst charging and when it wasn’t charging, but having used the Renault equivalent, I’m a very frustrated; it has to be plugged in to be able to check the battery level with the app, and I can only check it every 20 mins, it’s very frustrating!
Does anyone know of a better app?!

I had a Rolec switchable charge point installed when I had a Leaf 30. Should I have the breaker switched?

It does not have to be plugged in to see battery % or estimated miles, but yeah only ~ every 20 mins and sometimes much longer especially if your phone or Zoe are in poor signal areas.

The limitation is not the app/website (although it is pretty poor); the limitation is with the Atos/Worldline system that Renault are using for their connected-car solution.

The car's TCU is responsible for periodically updating Renault's server with its current state (state of charge, range estimate, charging cable state, probably a bunch more things that don't get exposed to us like location). By default this is configured to be every 900 seconds while the TCU is awake, or when the state of charge changes by more than 5%. (I could be wrong on those exact values, it's from memory.)

The TCU will eventually switch into a low-power state when the car is off (and not charging), at which point it won't "phone home" until it gets woken up, so the server won't receive updates.

Server-side, the only(?) way of communicating with the car is by sending it a text message (no, really), and the system places limits on the frequency that messages get sent out, hence the somewhat arbitrary "you can only request an update every 20 minutes". Note that if the car is charging, it'll periodically send updates to the server anyway, but there's no way in the app to say "get me the latest update from the server" as opposed to "get the server to tell the car by SMS to send an update back to the server".

In addition to what @jamesremuscat said: The car basically sends periodically when it is awake, which in a practical sense means it pushes messages while driving, while charging, and when opening the door. I am pretty sure it also drops a message at the end of charge . It is actually a pretty efficient method because if the car is asleep it is not driving and not charging so the status is static.

Problems arise when the car can't reach the infrastructure, or the SMS isn't received, which does happen as the TCU seems to be a bit weak. The back end can't determine if the car went to sleep or is out of reach.

The SMS method might seem archaic but there is nothing wrong with it. The alternative is to keep the connection always on which is very inefficient as it uses TCP keepalive packets that are not aligned with the cleverly designed power saving modes of the GSM network. I am led to believe the SMS coaxes the TCU to set up a VPN not just to drop the battery message, but enables the techs to get in and do some diagnostics.

Now if the goal was to get to the car in real time at any random moment, it is obviously the wrong approach, but I dare to say that was never the design requirement. I can't think of a reason why t would be.

The "get the latest update from the server" is actually what it does when you start / restart the app. In the message is the timestamp that last data was received from the car. I pick that up every 15 minutes in my Node-RED automation and sure enough when the car is asleep the last received time can be hours or even days in the past.
