Hi,
i use Libreelec 9.0.1 and the Xonfluence Skin. In Settings / Power saving / Shutdown function i have set up 'shutdown'. But when i press the button there is the shutdown menu where i can choose Exit or Power off System and others. I use this IR-Receiver (index.php). The cable that normally connects the Button with the Pinon the Mainboard to Power off the device goes to the IR-Receiver and from there an extra cable to the Pin. This worked since years. I only use the IR-Receiver to Power the device on not to control Kodi when its running. For that i have an other IR-Receiver (MCE Remote). Power on with the Remote and with the On/Off Button works. Power off with the remote works also but first the shutdown menu opens and then the device goes down. So i think there is the same problem but the shutdown works because the remote sends an additional shutdown command to the MCE receiver.
Any idea why it isn't working with the on/Off Button?
