EVCC Keeps freezing and crashing

[djfanatix]

Describe the bug

EVCC UI Freezes and crashes

Steps to reproduce

I cannot find anything relevant in the logs
It seems it starts fine and then it freezes.
The UI is also frozen, it does not change.
It initially fetches the values from modbus and homewizard, but then nothing (freeze) and a reboot after a while

I tried to remove circuit, no effect.

But I added a log anyhow.
EVCC 0.126.6
HA Addon

Configuration details

What type of operating system are you running?

Version

0.126.6

Please see #8009 for diagnosis.

I deleted the addon and reinstalled, and then I disable the circuits and now it works again.
If I enable the circuits EVCC hangs after startup.
Is something changed for the circuits since 0.126.4 or 0.126.5?

[andig]

Are you saying going back to 0.126.4 works again? You'll need to share the config that leads to this.

[djfanatix]

Ok I did do a lot of trials and now I got a backup working again.
So if I disable the 'circuit:main' in the Loadpoints, it works again.

I also tried with parent circuits in the Loadpoints, but this doesn't work

You MUST NOT add the same circuit twice, so not doing this on the loadpoint is correct. I think we should validate that a higher-level (site) circuit cannot be reused on a lower level (loadpoint).

Correct. Should never be used twice in the circuit tree.

[andig]

Not sure I follow. What should not be used twice in the tree? Question here is if a root circuit can have loadpoints assigned I think? I'm not entirely sure what we should expect.

Closing as config issue. #14244 will prevent this kind of mistake.
