Hi all,
I still have problem with a custom component that wrote for me, it use to work until the the 0.87 version, with the grat migration done, but from the 0.88 it doesn’t work anymore, I wrote here:
How to "package" custom_components
Is anyone able to help me to have it working?
If you need to spend time on it, I can sponsor it.
Let me know
Thank you
