Hello again.

Thanks @sdetweil :)

I’m now using MMM-Universal-Pir from here: https://gitlab.com/khassel/MMM-Universal-Pir

This is my config to turn the screen (connected via HDMI) on/off :

module: "MMM-Universal-Pir",
                hiddenOnStartup: true,
                config: {
                        gpioCommand: "gpiomon -r -b gpiochip0 4",
                        onCommand: "vcgencmd display_power 1",
                        offCommand: "vcgencmd display_power 0",
                        deactivateDelay: 60 * 1000,
                }

regards
