Home-Assistant freeze/pause during startup/initialisation

grewhit25 commented 4 years ago

The problem

Home-Assistant (core) will freeze/pause during startup/initialisation under certain conditions.

I raised #30759 to investigate because I was of the opinion the issue was related to my TPLink smartplug being powered off during HA startup but the dev there believe that the underlying issue is not caused by TPLink integration..

The issue manifests itself, in my case, if a previously online TPLink smartplug is then powered off followed by stopping, removing and restarting the docker container running HA.

During the frozen state, one option is to do a docker restart of the ha-container which causes HA to not freeze at the same point. However, in my case that broke SmartThings integration #30760

I have since discovered that while HA is in the frozen state you can simply power-up the smartplug; once it's back online HA continue its initialisation automatically.

An unusual situation to be in I know. The background is; during the xmas period one smartplug was used to manage some extra lights. Once that was all over the offending smartplug was powered off and left powered off.

I am on HA's Dev channel with auto updates through docker watchtower so this issue was a daily occurrence at one point.

The problem is still evident as of release 106.0 and can easily be recreated using the steps above.
