PoE is running at around 50-ish Volt, so even less current through the wires.

Nice weather enables opening and inspection of the boxes of the setup.
Visual signs of shortcircuit in the circuitry of the capacitive fork, probably due to intrusion of water/condensation:
at location where those effects first could be expected ....
That is probable cause of the earth-short mentioned in earlier messages, kicking out the related 230V-group,
because now the power supply etc. restarts without problem.

Have 'raised' the DS18B20-array and presently rebuilding for 'underground'-configuration with 5*DS18B20 and 4*PWM-sensor.
