@patman15 Hi Patrick, could you please look into this issue?

This is an issue with batmon. Sorry, but I cannot help here, as I don't maintain it.

This is NOT an issue with batmon. This is an issue with something in home assistant, likely a dependency like docker. I bet you it's docker. It worked fine till I moved to a new server and had to reinstall HA that is now too new of a version.

Still I don't see the connection to me and how I can help. It's outside my area of knowledge, i.e. the aiobmsble library that is used by batmon.
Also the error "An unknown error occurred while trying to build the image for app 2af0a32d_batmon" is not very descriptive...

[patman15]

@humzalam I think joagonca provided the fix that you are looking for ...

[hamster66]

@patman15 Please explain why the pull request from joagonca still isn't merging? This very useful app hasn't worked for three days now... :( I mean the standard installation in HA

[patman15]

Dear @hamster66 I won't explain, because I can't, I'm not the maintainer of this repo. I just checked if there is an issue with the library of me that fl4p is using from me. There is not. Please talk to fl4p.
