I've already tried that command, but the lib vcgencmd seems not available.

Code: Select all

vcgencmd: command not found


I'm using the distro provided by OpenMediaVault


Perhaps you should be seeking advice from whoever builds/maintains/distributes that third-party Operating System?

Just issue led.on() immediately after led.blink() concludes?

Or implement your own version of led.blink() that works to your own preference. The source code for the released version is here: https://gpiozero.readthedocs.io/en/stab ... s.html#LED
