The factory default is to enable the automatic management feature for environmental sensors and actuators. Therefore, when the total number of managed sensors and actuators has not reached 32 yet, the PXE automatically brings newly-connected environmental sensors and actuators under management after detecting the connection of these sensors and actuators.
When this feature is disabled, the PXE no longer automatically manages any newly detected environmental sensors and actuators, and therefore neither ID numbers are assigned nor sensor readings or states are available for newly-added sensors and actuators.
Note: The PDU folder is named "my PX" by default. The name can be customized. See Naming the PDU.
