Retrieves a electrical power sensor for a given identifier. The identifier can be specified using several formats:
-
FunctionLogicalName
-
ModuleSerialNumber.FunctionIdentifier
-
ModuleSerialNumber.FunctionLogicalName
-
ModuleLogicalName.FunctionIdentifier
-
ModuleLogicalName.FunctionLogicalName
This function does not require that the electrical power sensor is online at the time it is invoked. The returned object is nevertheless valid. Use the method YPower.isOnline() to test if the electrical power sensor is indeed online at a given time. In case of ambiguity when looking for a electrical power sensor by logical name, no error is notified: the first instance found is returned. The search is performed first by hardware name, then by logical name.
If a call to this object's is_online() method returns FALSE although you are certain that the matching device is plugged, make sure that you did call registerHub() at application initialization time.
- Parameters
-
func | : a string that uniquely characterizes the electrical power sensor |
- Returns
- a YPower object allowing you to drive the electrical power sensor.

Starts the enumeration of electrical power sensors currently accessible. Use the method YPower.nextPower() to iterate on next electrical power sensors.
- Returns
- a pointer to a YPower object, corresponding to the first electrical power sensor currently online, or a NULL pointer if there are none.
