Integration messed up the ./storage/core.config_entries file somehow

[cryptedx]

Hi,

Describe the bug
I had the issue that I could not edit, remove and add integrations. See also issue I created this: home-assistant/core#123949

The root cause was, that the meross integration messed up the ./storage/core.config_entries file somehow.

I have just run into the same issue. I had several integrations unrelated to Meross that would require re-authentication every time I restarted HA. After about a week of troubleshooting I stumbled upon this thread:

https://community.home-assistant.io/t/changes-on-integrations-are-reset-after-reboot/782085/8

That tipped me off to check the Meross config_entries file and I found that this part of the Meross entry:

"mqtt_domain":["mqtt-eu-4.meross.com"]

...looked like this:

"mqtt_domain":[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[["mqtt-eu-4.meross.com"]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]]

I removed all the unnecessary [ ] and restarted, and all the integrations that were failing worked again. However, when I went back to check the Meross config_entries line, it now looked like:

"mqtt_domain":[["mqtt-eu-4.meross.com"]]

I tried rebooting again, and it looked like:

"mqtt_domain":[[["mqtt-eu-4.meross.com"]]]

So it appears that every restart causes another [ ] pair to be added for some reason. Strangely, the failed integrations still work, so it seems that at some point Home Assistant can't cope with all the brackets and weird stuff starts to happen.

Afraid that's as far as I've got, but hopefully will be of some use...

You are right. It's starting again:

mqtt_domain":[[[[[[[[[[[[[[[[[[[[[[[[[[[["mqtt-eu-4.meross.com"]]]]]]]]]]]]]]]]]]]]]]]]]]]]

ugh
