I’ve been using Logitech Harmony Remote for a long time to control my Home Theatre. They are (were) an amazing product and it’s such a shame that Logitech stopped manufacturing new remotes in 2021 and then discontinued the Logitech Harmony Remote Software in 2025 which cut support for a significant swath of owners out there.
I’m fortunate that I managed to get my hands on a Harmony Hub and Elite Remote when they were still being manufactured so these changes haven’t affected me yet. That being said, it’s only a matter of time right?
I started looking around to see what was out there for the inevitable day my Harmony stops working and there are multiple Open Source projects looking to keep Harmony alive since it’s doubtful Logitech will Open Source everything. On top of that there are plenty of remotes from other manufacturers you can use.
The one thing I noticed they were all missing? A massive database of IR codes. That database is what made Harmony great. Not that sitting down for an afternoon and capturing all the inputs from your remotes is a huge deal, but wouldn’t it be nice if you didn’t have to?
Now you don’t: https://github.com/pickysysadmin/logitech-harmony-ir-archive
AI Disclaimer: I heavily used AI in creating this archive.
The original data (Logitech’s IR Codes and Protocols) are all preserved as they were captured. I took the liberty of converting them all to Pronto, which seems to be the closest thing to a universal standard, and appended them to the archive to hopefully save time. If the conversion is wrong (cause hey, AI makes mistakes) the original data is there to fix it.
The archive contains ~276,236 unique devices, ~13,293,293 IR codes and ~684 protocols. Some devices were removed during final processing as they did not have IR codes associated with them (HID/Sonos/Roku).
I will attempt to keep the database up-to-date, if Logitech is still updating it, and they don’t block me. The last device I pulled was a TCL 75Q77K which might have been released around March 2025 which was 2 months before Logitech announced the discontinuation of Logitech Harmony Remote Software. Hopefully that is just a coincidence.
If there are errors in the conversion between Logitech’s format and Pronto let me know via an issue in the Github repository. I will do my best to correct it. I only have 4 devices that use IR and my Flipper Zero is still in the mail so I can’t really test anything.
