I’m in the same boat honestly. I just wanted to turn off my bedroom light without getting up, and now I’m deep in research mode over something I thought would be simple. I ended up just sticking with the app for now and it works fine for my one bulb, so I’d say don’t stress about the hub unless you start wanting more lights.
Took me a solid week before I stopped noticing the shape, but after that it just felt normal. My shoulder pain didn’t fully go away but it got a lot better than before.
