3 Day Blinds Smart Hub and Motion Blinds integration

I understand that the Motion Blinds integration is reported to work with 3 Day Blinds. I have several, related questions for anyone with experience or knowledge on the topic.

Does anyone have experience with this combination?
Did you use the 3 Day Blinds Smart Hub or some other Hub to connect to the Motion Blinds integration? If using the 3 Day Blinds Smart Hub, how was the API key retrieve?
Any limitations or quirks to be aware of?

Thanks for any help on this.

Have you successfully set this up? Looking at 3DayBlinds for our remodel. Any issues?
