RPI mceusb configure power button to HDMI on/off

Hello,

I have RPI3 with libreelec running Kodi 18.

I have problem - I want to turn HDMI output on/off with remote button.

My plan:

1. when I press power key on mce remote, libreelec executes -

vcgencmd display_power 0

2. when I press power key again on mce remote libreelec executes:

vcgencmd display_power 1

I can run these commands trough SSH and screen is On/Off and system keeps running as is desired result to keep samba running

Please advise how to to do this.

I have no clue how to do it, just some google searches that have not resulted in final result.

I never tried it, but maybe you can map "System.Exec" to the power button. See here.

It looks like painful stuff.

Irexec might be solution but I don't know how to get it working

Is there someone who could give some decent advice to this?

Did you try the full path to vcgencmd?

what you mean by full path?

googling here an there, i found that there is no key id for mce remote power buttion.

Thing is that key editor and lirc treat mce remote as keyboard,e.g. KEY_RED is actually key id=251.

And mce power shuld be KEY_SUSPEND and there is no key id for that.

I tried to turn debuging on and all I saw was KEY_DOWN, KEY_UP, suspend or other didn't apear at all.

checking with ssh running irw all I can see is KEY_DOWN, KEY_GREEN etc without key id.

LibreELEC:~ # irw

6c 0 KEY_DOWN devinput

67 0 KEY_UP devinput

69 0 KEY_LEFT devinput

6a 0 KEY_RIGHT devinput

18f 0 KEY_GREEN devinput

190 0 KEY_YELLOW devinput

191 0 KEY_BLUE devinput

20b 0 KEY_NUMERIC_POUND devinput

20b 0 KEY_NUMERIC_POUND devinput

200 0 KEY_NUMERIC_0 devinput

8e 0 KEY_SLEEP devinput
