hello everyone, hope right place post question.
have rpi 3 model b i'm using openelec. tv has usb ports on it, used power rpi 1 b+, such when tv turned on, pi boot up. unfortunately, usb port doesn't supply enough power power rpi 3. directly plug wall, it'd running time. ideally, i'd turn on when tv turns on, , turn off when tv off.
i'm wondering if there relay of sorts usb power. example, i'd have pi plugged wall through relay, , when relay detects power tv's usb port, send power wall pi. exist? or have other creative solutions?
thanks!
