I have a few older RB411AH, that not shows voltage at /system helath print:
[admin@MikroTik] > system health print
[admin@MikroTik] >
Why? Other RB411AH - shows it without problem, but what is with these?
Is that any RouterBoard failure?
What ROS are you running?
It doesn’t work on mine running 3.30 but does work on 4.17.
