HOWTO: temporarily disable heartbeat after login


echo ‘none’ | sudo tee /sys/class/leds/user_led1/trigger

This disables the heartbeat led until the next system reboot. This is useful if you have separate indicator LEDs (eg the sensors mezzanine) or if you don’t like/need this led. You can reenable the heartbeat function using,

echo ‘heartbeat’ | sudo tee /sys/class/leds/user_led1/trigger


Thanks for the tip! : )
