Great post with lots of detail! I have had MyQ for years and hated it pretty much at first use. Back then, they were asking for a monthly fee for the "privilege" of integrating it with Google.
Since the MyQ integration for HA is now dead, I have ordered a Ratgdo and am patiently waiting for it to arrive. I tried the Anthom.tech opener, but that does not work with most Chamberlain/Lift master opener made after 2011.
I second Paperless NGX. I have been using it for a few years, and it has been working great!
