thanks for the replies.
Right now I’m using my tried and true hacked dry-contacts-soldered-across-the-button-of-a-remote solution for both brands (I have one of each). And both doors have their stand-alone position sensors as well.
The ratgdo sounds good but I was wondering if the benefits I would gain are worth the extra cost since what I have now has been working for years.
It might give a bit more functionality for Chamberlain (that I likely wouldn’t use tho) but it sounds like for Genie there isn’t much advantage.
With the schematics offered above I may just try to DIY my own Ratgdo for the Chamberlain at some point. The biggest downside with my current solution (if you can call it that) is needing to change the remote batteries every few months. Not really a major thing but it means I have to get a ladder out to pull the remote out of its hidey-hole. A powered solution would solve that.
