Managed vs Unmanaged Sensors/Actuators

To manually manage or unmanage/release a sensor or actuator, see
 Managed sensors/actuators:

Legrand PDU communicates with managed sensors/actuators and retrieves their data.

Managed sensors/actuators are always listed on the Peripheral Devices page no matter they are
physically connected or not.

They have an ID number as illustrated below.

They show one of the managed states. See

For managed 'numeric' sensors, their readings are retrieved and displayed. If any numeric sensor is
disconnected or its reading cannot be retrieved, it shows "unavailable" for its reading.
 Unmanaged sensors/actuators:

Legrand PDU does NOT communicate with unmanaged sensors/actuators so their data is not retrieved.

Unmanaged sensors/actuators are listed only when they are physically connected to Legrand PDU.
They disappear when they are no longer connected.

They do not have an ID number.

They show the "unmanaged" state.
