This is the first alpha release that might be useful. Feel free to have a play, but don't assume it's finished.

Be aware that this will require some technical knowledge, as it doesn't take the "I'll take you by the hand" approach you're used from the Harmony software.

supported functions:

* only the harmony 900.
* remote backup and backup restore.
* reading and importing config from the remote, writing new config back to the remote
* adding / removing devices
* adding / removing / learning IR commands (IR protocol and "raw" mode). most common protocols are supported.
* manually creating and editing IR commands (IR protocol and "raw" mode).
* assigning device and activity buttons to the IR commands
* editing device control (input / power state machines)
* non-supported config items >>>should<<< just be copied trough and continue to work as before.
* does some basic consistency checks, and refuses edit/delete when this would break the config. not guaranteed to be complete.

not yet implemented

* editing activity control (power, inputs)
* without that, adding activities is mostly pointless (but possible)
* TV channel touch icons

not supported

* No access to the Logitech device lib.



general:  
as this is a reverse-engineering project, some parts are not fully understood and might break. do a backup of your remotes config first, in case something doesn't work out.  
I did some testing, but assume that there will be bugs :-)

install:

* download here: [https://github.com/martin-wagner/harmony900tools/releases](https://github.com/martin-wagner/harmony900tools/releases)
* linux:
   * follow [https://github.com/martin-wagner/harmony900tools/blob/main/tools/linux-plug-setup/install.md](https://github.com/martin-wagner/harmony900tools/blob/main/tools/linux-plug-setup/install.md) . The remote must be reachable under IP 169.254.1.1.
   * download the appimage, set executable and start.
   * or download and install the debian package (debian 13).
* windows
   * install the harmony remote software 7.8.1. this package will install the driver for the remote. With that, the remote must be reachable under IP 169.254.1.1.
   * download and run the installer or the zip.

use:

* connect your remote
* click on "connect"
* click on "connection -> create remote backup". keep this file in case something goes wrong.
* import your settings by clicking "connection -> read config from remote". This will create a new project. save this to your PC.
* do your edits
* click on "write config to remote"
* save your project. You should not re-import from the remote but continue to use the file.

If something goes wrong, create an issue on the github project page. attach your project and the displayed log. Be aware that the project file contains your name and a logitech ID.
