concordance - for programming your Logitech Harmony remote control



concordance <file>
concordance <options>


This software supports programming Logitech Harmony remote controls. This software uses libconcord, which in turn uses libusb, which requires the RAWIO capability. That means you probably need root to use it.


Read the config from the remote and write it to a file. If no filename is specified, config.EZHex is used.
Read a config from <filename> and write it to the remote.
Read firmware from the remote and write it to a file. If no filename is specified firmware.EZUp is used.
Read firmware from <filename> and write it to the remote
Print this help message and exit.
Print information about the remote. Additional information will be printed if -v is also used.
Get time from the remote
Set the time on the remote
Learn IR commands from other remotes. Use <filename>. When you selected multiple commands to learn on the Logitech website, you can move through this command list and let the Harmony learn the IR code for each command.
Reset (power-cycle) the remote control
Read the safemode firmware from the remote and write it to a file. If no filename is specified, safe.bin is used.
Do a connectivity test using <filename>
Print the version and exit


When dumping a config or firmware, this specifies to dump only the binary portion. When use without a specific filename, the default filename's extension is changed to .bin. When writing a config or firmware, this specifies the filename passed in has just the binary blob, not the XML.
Force. This forces concordance to use the file the way you specified, even if it doesn't think that's the kind of file it is. This is necessary for files dumped by concordance.
For config or firmware updates, do not reboot the device when done. This is generally only for debugging.
Enable verbose output.
Do not attempt to talk to the website. This is useful for re-programming the remote from a saved file, or for debugging.


None known at time of release, but check the website.
