Addon can't be removed


I’m trying to remove an addon that I am working on, however the UI doesn’t let me. When I click “Uninstall” I get the following Supervisor log:

18-02-20 20:06:14 ERROR (MainThread) [aiohttp.server] Error handling request

I installed it by adding GitHub repo and it’s version doesn’t follow anything close to SemVer versioning. Is there any way for me to access the installed files over SSH and remove them by hand?

I am having a similar experience with a local add-on. Something went wrong during some experiments and now I have an add-on with a green jigsaw icon and only a start button, no stop or uninstall.

The log file mentions on one hand that the add-on is already installed and also refers to an older config.json entry that is no longer present.

Does somebody know if there is some cache to clear?

I would login on SSH and remove the docker container manually

Thanks for the tip. That is exactly what I’ve done using the following commands using the hassio cli

hassio ad list
hassio ad -name <name_of_addon_to_remove> stop
hassio ad -name <name_of_addon_to_remove> uninstall

Hopefully this will help somebody else in the future. I’ll get back at trying to recreate the custom addons in the mean time.


The command changed but still in my case it can’t find the slug, while the UI still shows it and marks it as used.
