I fixed two issues with my limited knowledge of Python and Home Assistant. You can find the modified files init.py and base.py in my GitHub repository https://github.com/wilbiev/UI/tree/main/custom_components/ui_lovelace_minimalist The solved issues are the hanging (problem in the reload of the integration) and the log messages 'Detected blocking call'

can you add these to the main repo?

I fixed two issues with my limited knowledge of Python and Home Assistant. You can find the modified files init.py and base.py in my GitHub repository https://github.com/wilbiev/UI/tree/main/custom_components/ui_lovelace_minimalist The solved issues are the hanging (problem in the reload of the integration) and the log messages 'Detected blocking call'

@wilbiev could you please create a PR just for those 2 files? It works for me also. I tried different fix: changing shutil for aioshutil (https://github.com/HuffYk/UI/releases/tag/v1.3.9-aioshutil ), but looks like it sometimes works, sometimes not. Your fix works so far (here I merged just those 2 files: https://github.com/HuffYk/UI/releases/tag/v1.3.9-wilbiev )

[wilbiev]

I try to find time to solve 3 remaining issues before creating a PR:

1. First time users still experience hanging issues after configuring the integration - cause: Minimalist does not save the initial configuration items correctly in the core.config_entries file. Workaround: adding the entries manually. When the entries exist they can be modified.
2. After configuring the integration 3 routines are run twice. This doesn't give side effects but is not very neat.
3. There are guidelines for submitting PR-requests. I was not able to setup a decent dev environment for the pre-commit testing. The provide template contains deprecated components and my knowledge is too limited.

[FG2300]

does this fix the hanging problem and if so how do i download this

[wilbiev]

I created a PR with the new code which should solved the hanging issue and the log messages 'Detected blocking call'. The code check fails while deprecated options are used for isort. Locally all tests were successfully passed. Let's wait for the review.

[wilbiev]

The code from the init.py and base.py files at https://github.com/wilbiev/UI/tree/main/custom_components/ui_lovelace_minimalist can be manually copy/paste to your local deployment. This should not be too difficult if you are able to write dashboards in code with UI Minimalist.

[lyneld]

Thanks a lot for sharing the fix @wilbiev but I still seem to have the hanging problem. I see you mentioned some issues with first time users (I'm a first timer here) - what steps should I follow? Here's what I did - installed UI Minimalist through HACS, installed all the pre-requisite cards, restarted HA, edited both init.py and base.py files (in custom_components/ui_lovelace_minimalist) with ones from your repo, and then proceeded with the integration configuration. This didn't seem to work and still hangs.

[karelkryda]

@lyneld I can confirm what you are saying. I'm currently trying to set up the UI with fixed files, but the integration configuration window causes my container and the entire HA to overload and crash.

So far, however, it seems that the UI is loading even without performing actions in the configuration window. So I'll try to do it this way for now.

[wilbiev]

@lyneld I have a few questions:

1. Did you select the GitHub-option when installing the UI Minimalist integration?
2. Did you restart HA after the installation steps and before configuring the integration?
3. Which version of HA are you using?
4. Are these options available in the config/.storage/core.config_entries file under domain "ui_lovelace_minimalist"?: "options": { "language": "English (GB)", "sidepanel_enabled": true, "sidepanel_title": "UI Lovelace Minimalist", "sidepanel_icon": "mdi:flower", "adaptive_ui_enabled": true, "adaptive_ui_title": "UI Lovelace Minimalist", "adaptive_ui_icon": "mdi:flower", "theme": "minimalist-desktop", "theme_path": "themes/", "include_other_cards": false, "community_cards_enabled": true, "community_cards": [] },

[karelkryda]

@wilbiev, let me answer your questions.

1. no, I didn't authorize Minimalist UI with Github
2. yes, tried multiple times
3. Core - 2024.6.4; Frontend - 20240610.1 in Docker via stable tag
4. no, my JSON looks like this:

   {
   "data": {
   "community_cards_enabled": false
   },
   "disabled_by": null,
   "domain": "ui_lovelace_minimalist",
   "entry_id": "8e0aa53862406d703587f0a49cc59907",
   "minor_version": 1,
   "options": {},
   "pref_disable_new_entities": false,
   "pref_disable_polling": false,
   "source": "user",
   "title": "",
   "unique_id": null,
   "version": 1
   },

[wilbiev]

@karelkryda replace '"options": {},' in config/.storage/core.config_entries under domain "ui_lovelace_minimalist" with:

"options": { "language": "English (GB)", "sidepanel_enabled": true, "sidepanel_title": "UI Lovelace Minimalist", "sidepanel_icon": "mdi:flower", "adaptive_ui_enabled": true, "adaptive_ui_title": "UI Lovelace Minimalist", "adaptive_ui_icon": "mdi:flower", "theme": "minimalist-desktop", "theme_path": "themes/", "include_other_cards": false, "community_cards_enabled": false, "community_cards": [] },

WARNING: editing the config/.storage/core.config_entries file is at own risk. A wrong config in this file can cause severe damage to your HA deployment!!!

[lyneld]

@wilbiev - similar to karelkryda, below is what I got:

1. No, I did not select the Gihub option while installing.
2. Yes, restarted multiple times.
3. Version I'm running is Core 2024.6.4, Supervisor 2024.06.2, Operating System12.4, Frontend 20240610.1.
4. My JSON looks pretty much like karelkryda:

     {
       "data": {
         "community_cards_enabled": false
       },
       "disabled_by": null,
       "domain": "ui_lovelace_minimalist",
       "entry_id": "01ea84bf542d55e3e240c324442a3f52",
       "minor_version": 1,
       "options": {},
       "pref_disable_new_entities": false,
       "pref_disable_polling": false,
       "source": "user",
       "title": "",
       "unique_id": null,
       "version": 1
     }

Will try your config changes and report back!

[karelkryda]

@wilbiev I've applied changes to the config. The changes were reflected in the UI, but after trying to use the configuration UI after the change, it caused the container to freeze again.

[lyneld]

Can report the same - I updated the config file. Restarted HA. Then went into integration, Minimalist UI and tried to configure but got the same "hang & crash" result. Interestingly though, my home-assistant.log.1 file has thousands (over 8000) lines of:

2024-07-02 00:09:11.202 ERROR (MainThread) [custom_components.ui_lovelace_minimalist.base] HACS Frontend repo "weather-radar-card" is not installed, See Integration Configuration.

Am I missing something? I installed all the required cards, including Simple Weather Card. Will try installing Weather Radar Card and see if that helps.

[karelkryda]

@lyneld The installation of 3 additional libraries is due to the adaptive template - see. Minimalist UI documentation. I personally installed these components, but it did not affect the result.

[warmfire540]

@lyneld 2024-07-02 00:09:11.202 ERROR (MainThread) [custom_components.ui_lovelace_minimalist.base] HACS Frontend repo "weather-radar-card" is not installed, See Integration Configuration.

these are 2 separate cards, you can see from the name of the card in the error

[lyneld]

Adding the weather-radar-card didn't seem to help. Its still stuck and crashing. I've also added the other resources recommended in the adaptive wiki (state-switch, layout-card). No luck though.

[wilbiev]

Issue can be closed. Solve by update v1.3.10.
