Timed out error Hass

[NiMa08]

After restarting, subsequently I'm getting these errors:

WARNING (MainThread) [homeassistant.components.cover] Setup of cover platform mysmartblinds is taking over 10 seconds.

Logger: pygatt.backends.gatttool.gatttool
Source: /usr/local/lib/python3.8/site-packages/pygatt/backends/gatttool/gatttool.py:387
ERROR (SyncWorker_3) [pygatt.backends.gatttool.gatttool] Timed out connecting to F4:6D:E5:54:1B:8D after 5.0 seconds.

Is this message because my keys are wrong? Or is it something else. I used an android phone to get them. I also have Ian Levasque Mysmartblinds Bridge client installed, but don't know how to get the keys with that?

(I also had to change the folder naming a little bit to install it. In custom components, I now have a folder named mysmartblinds and renamed the file mysmartblinds.py to cover.py. Also changed CoverDevice to CoverEntity since that was deprecated.)

I'm still trying to get this to work, if you could take a look at the keys I retrieved and tell me what I need, then I can narrow down the problem. This is all I'm getting out of the snoop log:
