Looking to gather more Harmony dumps

As part of my work on the offline config generator, I need .ezhex config dumps from other Harmony models to evaluate how similar they are to the 900 and what it will take to support them.

​If you have one of the Concordance-supported models below, please dump your configuration and send it to me.

Supported Models:

  • 6xx series
  • 36x, 51x, 52x, 55x
  • 700, 720, 745, 748, 768, 785
  • 88x, 890, 895
  • 900, 1000, 1000i, 1100
  • 200, 300
  • One, Link, Xbox, AV-100, TC30

Instructions:

  1. Plug the awake remote into your PC via USB.
  2. Download Concordance:
  1. Open the install folder in Command Prompt/Terminal and run: concordance -w -c backup.ezhex
  2. DM me the .ezhex file along with a brief list of the devices your remote is configured to communicate with.

Thanks!

Progress update on reverse-engineering the Logitech Harmony 900 configuration files

Hello there! Quick update on the Harmony 900 reverse-engineering project I posted about a while back asking people to send .ezhex dumps.

The reverse-engineering side is basically done. I can now build a config from scratch - no Logitech servers involved - flash it to my own Harmony 900 over USB, and have it work exactly like it worked before.

With the file format solved, the next phase is an actual GUI so you don't have to use a script to make a config. Plan is a wizard-style flow: pick your devices, assign buttons, build activities, export a ready-to-flash `.ezhex` - basically what the old software did, minus the dependency on Logitech's servers.

Alongside that, I'll be setting up a GitHub repo where people can contribute and pull device configs, so instead of everyone reverse-engineering their own gear from scratch, we build a shared library of TVs, receivers, cable boxes, yada yada, that the wizard can just pull from.

Once the tool is further along I'll post again with something people can actually try. If anybody, drop a comment and I'll follow up when there's a build.

I've attached images of the actual device working with one of my handmade configs

Thanks!

Edit: if you have any Logitech remote that's supported by concordance, find my previous post on the subreddit and dump the config, then send it over. If the remote is similar in configuration to the 900 it will get support too easily, but without a dump I wouldn't be able to know for sure. Theoretically the 1000 and similar are supported but Im not totally sure
