CvH I'm wondering, Is it possible to use the remote control supplied with the tt-4600 for example with libreelec?
I've created a keymap for the S2-4600 about two years ago, but not used it (and never tested with LE9). Use ir-keytable -c -w <file> to load.
There are some issues: all keys are using two different key codes (handled by the keymap) and there is a fast autorepeat than cannot be configured.
