I had thought about it too ... the tvbox is for a 3d printer for which I succeed in my intent but I also needed only a signal to drive on / off for a 3.3v SSR, in order to turn the whole system on and off from remote .... I used the command "gpioinfo" to search for active pins and convert them for other purposes, but I don't know how to change their status via cli ... in case it fails in my intent I will fall back on usb relay or on the sonoff system with mqtt ... how can I vary their status knowing the actual position on the board? the pin I need resides in / gpiochip1 / gpio19. the pin in question is used by the system to power the 5vs needed by the HDMI but since I don't need it, I can use it to drive the SSR

Hi! i installed armbian on my tvbox with SOC s905w 2gb and i would like to control a relay via linux .... is it possible? and how? thank you
