BG SyncEV Rebooting Constantly

[M450NC]

I have a BG SyncEV charger. I have set up the OCPP server URL on the charger and I am able to briefly control the charger via home assistant however the charger seems to be constantly reconnecting/rebooting and everything goes unavailable and then comes back.

I enabled debug logging and here are some of the latest logs in home-assistant.log:

The above exception was the direct cause of the following exception:

Thanks in advance for any assistance, I'm fairly new to this so please let me know if you require anything else.

[drc38]

The charger is not ocpp compliant, as it does not report back any SupportedFeatureProfiles

Thank you for the quick reply.
That's a shame. Is there work around possible for this or no chance with controlling this charger with home assistant?

[drc38]

Look through #899 for various hacks that can be used on non-compliant units

[ganterd]

I have the same charger, and had the same issue. I had to modify the code a bit to extend a timeout, and ignore the SupportedFeatures issue.

I'm not able to post a diff at the moment, but when I get a chance I'll do it.

Oddly I've been charging with a BG SyncEV and this addon quite happily for a few months now. I've reboots a few times a day in the logs but they never seem to have caused an actual problem getting my 12:30am - 4:30am charge every day. However today something's gone wrong after updating HA and I had to edit the config to remove a hertz field which has apparently disappeared. It's late here and I'm basically confused and not sure if anything is working on not, but I just wanted to say until today I've been charging quite happily for a few months without any serious issues. The reboot notifications were annoying but that's about it. I'll check in again once I've worked out what (if anything) is going on.

Hi, i have a A-Tronix wallbox and ocpp 0.5.1. works but Updates greater 0.5.1 are rebooting too. Sorry for my incredible english.

[kerdridge76]

downgrade smaller 0.5.2 are not available at HACS

[hermanhobnob]

Just l came back to say I'm running version 0.5.2 and my car charged fine last night so I don't seem to have a problem apart from reboot notifications every few hours which I've set up a automation to ignore. I am however now reluctant to upgrade 😁

[Siumba]

I have the same issue on 0.5.2 or higher. Every few hours the charger seems to reboot. I downgraded to 0.5.1 (downloaded a release and copied the files over manually in the custom_components folder, and on 0.5.1 I haven't seen one reboot yet. Something seems to be off in the higher versions.

EDIT: after using 0.5.1 for a while I still get regular reboots every few hours.

Hi, I'm still trying to deal with this issue, if you can, please post specifically which files you modified and what parameters you changed? I've been trying for a couple of weeks to solve this. It seems like it is a timeout issue here as well, ocpp will talk to my charger properly for around 1 min, then disconnect, and then around 30 seconds later it will reconnect, reporting that the charger rebooted.

[ArtjomE]

Hi,
I have a Vestel EVC04 Charger. Overall, it works well, but I receive the same error message "Ocpp integration: Charger 7000262321000253 rebooted" every minute while charging. When it's in the "not connected" state, the message appears sporadically every few hours.

OCCP Version v0.5.8
Vestel EVC04 Firmware: v3.150.0-1.0.144.0-v7.0.14

[Crown3r]

Same here! Does somebody have found a workaround or something?
