I think your timeline might be off.
Hubitat has only been around since the Spring of 2018.
And Bryan’s Send IP2IR app (linked thread in a post above) was released in October of that year.
The discussion thread, and his code, are still available.
But this may also be relevant for you:
That disclaimer was added to all of the dev’s threads a couple years ago.
@buckchucko if you have questions about a community developer’s work, I suggest you post in the release thread for that driver/app now that you’ve been pointed in the right direction.
If you’re looking for a new solution to control devices with IR remotes, there are a few options to discuss in a new thread like this one. All of them have some downsides though.
