Ohme epod stopped communicating with car

[C-J]

Approximately 2 weeks ago the Ohme set-up seems to have stopped communicating with the car (2022 Renault Zoe) - the Ohme App isn't showing the battery % and range.

Instead there is an 'estimate' of the %charge - no idea what informs this estimate, especially as it is nowhere near what the car/Renault App show - with a field to input the current % charge manually.

From there I can schedule a charge as normal - however as it doesn't seem to know the actual charge during the charging process, how close it gets to this is random. 7% under to 15% over.

Anyone else had this comms issue.

I have tried signing out of the Ohme App, installing on another device, unpairing the car (although that seems to have left things hanging as now no pair OR unpaired option), registering a 2nd identical car in the App - it still doesn't see the current status.

Renault App and everything else seems OK.

An API change by Renault or Ohme perhaps?

Any had this? Or know what to try?

Thanks for sharing.

Good that the Skoda is close enough - and has a cut-off control.

From memory I don't think that the Zoe has setting car-side to stop at x% - happy to be corrected though.

Trying a few different search terms I found this

From 1 week ago, apparently Ohme found an issue with Renault API so turned off for now - hopefully not forever.

So I guess now just wait, hope and keep trying?

I thought the general advice with Ohme chargers is not to even try and integrate it with the car - vehicle manufacturers API's are just too flakey.

Good point
My Skoda is not actually paired.
If it s not paired, you just manually enter current battery level and target charge, and the charger calculates how much energy to add based on that.
So it s working correctly in my case

Aha - new news to me.
Maybe I've just been lucky that it has largely worked until now.
There are a lot more rules to this 'just get an electric car and simply plug it in' than I initially realised!

So 1 month on - and Ohme still requires the actual start % to be entered manually.
And then whilst it charges ok, it doesn't seem to be able to read the car's actual % during charging - as it stops at +/- 5% of whatever target I set.

Not the end of the world - but not how it used to work!

Just wondered in anyone else was seeing this change for Ohme / Renault (Zoe) interface?

Note: At plug-in, Ohme does 'estimate/'/propose what the current % might be - however I have no idea what that is based on. As it can vary by +/- 5% to 50% of reality!

Same behaviour as my Skoda now.
The battery level is usually wrong when I plug in, I correct that.
But it charges ok!

i never even look at my app, i dont even change which car we have plugged in, the cars are set to stop charging at 90% and not had a problem yet

Mine does the same with my Tesla. Weirdly the wife's id3 works fine. I can't register my new Tesla and just go by the battery percentage.

When I need 100% charge I can sometimes wake up with 85% with the app saying it has adjusted my target as it won't reach it in time. I see that it's charging at 3.68kwh so no wonder..I put it on max charge but still get the 3.68 charge rate!

It resets itself I think as I can plug in at 4pm and wake up with this scenario and it will say that I plugged in at 11.54pm for example.

Update: Renault App and Ohme App still not on speaking terms - so need to input current % manually.
Not a big problem. However...

Fri night: Set charge via Ohme App from 80% to 85%. Checked schedule breakdown - all ok.
Woke up to car at 80% (i.e. not increased).
Checking activity breakdown it had started as per plan at 4am, then stopped.

Sat night: Set charge via Ohme App from 20% to 80%. Checked schedule breakdown- all ok.
Woke up to car at 91% (i.e. 11% over target).
Checking activity breakdown it appears to have stopped because of the 6am cheap rate time stop (i.e. completely ignored the 80% max request)
Correct car parameters still saved in App (52kW battery etc)

Sit-rep: Ohme cannot read Renault %, but more concerningly Ohme doesn't adhere to the targets input into Ohme - and sometimes doesn't stop!

Did re-install Ohme App back in June when comms issue started. Nothing changed since then.

Any thoughts welcomed.
