For Devs: Mirror of the Logitech Harmony IR Database
I've posted in a few spots as comments and DM'd a few Devs directly but it seems there are multiple people publicly and stealthily developing Apps for those who's remotes have stopped working and those of us who's remotes will likely soon stop working.
This weekends outage of Logitechs servers finally convinced me I should make a dedicated post so this is easier for people to find.
I believe I have a complete mirror of Logitechs IR Database including protocols for how to decode the IR codes, timings, etc. as of 2026-10-05.

Now that I've posted this, the risk of DMCA is higher so I'd recommend mirroring a copy if you intend to use it with your app.
My hope is this will help app developers get their apps out quicker and save them the time consuming process of figuring out how to archive the codes and eliminate the need for their apps to talk to Logitech at all.

Before you ask, no I will not share my code or method. I'd like to be able to refresh it if Logitech adds anything new. Sorry.
