Concordance

This software allows you to program your Logitech Harmony remote using a configuration object retrieved from the harmony website

The website is required. The website is required in Logitech's software as well, it's just that their software wraps the website. Their website has all the logic on what codes work with what remotes and what hardware, etc. The software just takes the binary blobs that the website makes and writes it to the remote control. This is true for both Logitech's software and this software.

However, this software has some extra functionality such as being able to dump (backup) your existing config, being cross-platform, and giving you extra visibility into what's actually happening with your remote.

NOTE: the Logitech web server now is setting a header 'X-Frame-Options: DENY' which prevents the update process from working correctly with Concordance. In order to work around this, you will have to use a web browser that ignores this header. For Firefox, the 'Ignore X-Frame-Options Header' Add-on has been used successfully. For other browsers, there may be similar add-ons available.

Installing

Concordance is packaged in a wide variety of Linux distributions and other OS package repositories. The easiest path is to use such a package if it's available for your OS/distro.

If it's not packaged for your OS/distro, then refer to the appropriate INSTALL file in this repository for your OS.

Usage

NOTE TO MAC USERS: You need to use 'sudo' since you don't have udev.

NOTE TO LINUX USERS: This assumes you have proper udev support setup (see the INSTALL.Linux file in the libconcord source). If not, you'll need to use sudo or be root.

0. I got a file from the website, do something useful with it.

   concordance <filename>

   This will attempt to figure out what to do, and do it. Note that the update process sends TWO files: a connectivity test and the update. You will need to do both.

1. Backup the config

   concordance --dump-config=/tmp/config.EZHex

   This will read the config off of your remote and write it to /tmp/config.EZHex. It's a good tool for development as well as backing up your config. This can however be created from the members.harmonyremote.com/EasyZapper website. The equals is needed if you pass in a filename since the filename is optional. If you don't specify, concordance will use 'config.EZHex' in the current directory.

2. Connectivity test

   Go to members.harmonyremote.com/EasyZapper, and when you're ready, choose "Update My Remote." Before Logitech provides an actual config, they will first attempt to do a connectivity test. Downloaded the Connectivity.EZHex file, and then run the test:

   concordance Connectivity.EZHex

   If that doesn't work, you can tell concordance what it is manually:

   concordance --connectivity-test Connectivity.EZHex

3. Write a config

   Once the connectivity test is successfully completed, the site will prompt you to download the actual config in a file called Update.EZHex. Save it and then you can use it with:

   concordance Update.EZHex

   Again, concordance should do the right thing here, but in case of problems you can explicitly tell concordance what to do with:

   concordance --write-config Update.EZHex

4. Backup the firmware

   Sometimes the site will want to update your firmware. Concordance allows you to backup your old firmware so you may later revert if you prefer. You can do this with:

   concordance --dump-firmware

   This will read the firmware off of your remote and write it to fimrware.EZHex. See "1. Backup the config" for more information.

5. Write firmware

   NOTE: This feature is only implemented for certain models. Please see supported models

   However for models we support this on, it works like this:

   concordance Firmware.EZHex

   Again, if you have a problem, you can tell concordance what to do explicitly:

   concordance --write-firmware Firmware.EZHex

There are other options - check out the --help one!
