Native integration with ESP Home will come once I figure out how to do it (or someone from here wants to help and create a PR) 
First I had to get a fully functional solution. Second, gauge the interest - if only 3 people end up using this, then there isn’t any reason to develop it further. I have no way of really gauging how many people own these door openers, and then of that group, how many want local control.
If the interest is there, I’ll keep developing it!
And regarding the rolling code & encryption - I reverse engineered it and in doing so discovered a major design flaw in the whole scheme that allows me to use a special set of static commands to control the door opener.
