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
