OHME Red lights error

[NewtoEV]

Has anyone experienced an error on their OHME charger where the side strips turn red and the screen says error? It gives no indication what the "error" is.
This has been happening for several evenings. There is no car plugged in and nothing charging. It just happens. I've tried to find out what it means but there's no simple OHME guide to error messages apparently.
Can anyone shed any light on this and what I should do about it? I've tried rebooting but it come back on the same.
Many thanks!

(I've blanked out personal details)

Does the charger eventually return to normal operation without intervention?

If so it could be the PEN fault protection being triggered by out of spec supply...if you have a voltmeter you could measure the supply.

Yes, it seems to return to normal. This just happens randomly at night (and it’s not been in use).
I’ll look into the supply, thanks.

It does sound like it could be excessive supply - as the load on the grid drops during off peak the voltage tends to rise, unfortunately that's when you want the charger to work.

I have this problem but on a Wallbox Pulsar Max charger. The house is in a rural area located right next to the transformer and I'm measuring typically 252V line input, the way to fix it is to contact the DNO (UK Power Networks in my case) and report the issue, they then connect a data logger to record the supply voltage over a period of time and if they determine it's out of spec will drop the voltage.

I haven't done that yet since I have a support ticket open with Wallbox for the issue - they diagnosed it as a faulty ribbon cable, they've sent a replacement and I'm now waiting for their installation engineer to fit. I still believe it's excessive line input but I wonder whether he'll 'tweak' anything else in the charger.

Do you have an app or web app for the OHME?

Similar happened to my Easee charger a few months ago, but you can see the voltage in the app. The DNO came out tout suite when I reported it was over 253V. It turned out there was a broken local substation and another near one had been mis-configured to cover the additional area. It was fixed the same day.

Edit: or maybe you could measure the voltage some other way, with a meter or smart plug, or get an electrician to bring a logger. I had a meter too.

This has happened to my ohme / octopus charger , I opened a file with them and it came back as over voltage supply , you will need to turn it off at the consumer unit, wait 10 mins and switch back on , should no ok then

I'd raise a support ticket with OHME they might be able to provide more info from the device telemetry it probably sends them.
