I did not write the Reactor Add-on installation method/package for Home Assistant and I do not support it. I have no idea how it works, and I don't have a setup to debug/troubleshoot with. Perhaps another user of the Reactor Add-on can chime in.
There was a related question/post in late December, here, and other recent posts. Check those out. They may provide some insight.
The user who originally provided that add-on is no longer providing updates, apparently. Perhaps someone else who uses this configuration would want to pick it up?
